1.1. Boomerangs can be dangerous if they are thrown carelessly.
1.2. Throw boomerangs only from a safe place where they have plenty of room to fly or bounce without danger of hitting anyone or anything.
1.3. If you see anyone in danger of being hit, warn him promptly and loudly.
1.4. Warn anyone on the field if your throw may endanger him. Make sure he is clear before you throw.
1.5. Do not enter another throwers circle without checking to see if it is safe and telling the thrower you are entering his circle.
1.6. Make sure that the area immediately around you, in all directions, is clear to a radius of approximately 30 meters.
2. Forward
This book describes the individual events conducted in USBA tournaments and sets standards for running them. Certain words have special meanings in these rules. These words are defined in the definitions section. An attempt was made to write these rules clearly and completely, and to cover most expected circumstances. If things happen that are not covered or not covered clearly, the intent is interpreted by the tournament officials. The intent is to make the rules as fair as possible to all contestants and to avoid creating an unfair advantage or unfair disadvantage to any person.
3. Definitions
Active Circle
Competition circle currently being set up or being used to run an event.
Advanced
The highest level/class of competition. Throwers considered the best or most competitive.
Board, USBA
Elected officials of the USBA. The board may act in place of the USBA President if the USBA President is not available.
Boomerang
Number of arms is unrestricted. To be a boomerang a stick must tend to return as result of gyroscopic precession caused by asymmetric lift. The lift is created as a result of a throw that gives the object rotation and linear motion. Other characteristics include:
- Materials – can be made from any non-metal material.Metal may be embedded or taped on but may not have exposed sharp edges.
- Other- No launching, propulsion, or catching aids may be incorporated in the boomerang.
Bull’s-Eye
Area inside the 2 meter circle from which throws are made. The marked line is outside the bull’s-eye. If a thrower touches the line during the throw – before the boomerang is released – no points are scored for the throw or catch. This area is designated 10 points in Australian Round and Accuracy.
Catch, Behind The Back
Legal catch during which
- the boomerang passes behind the competitors back or
- the catching hand is behind the competitors back and withdraws the boomerang (Catches on the other side are permitted if the catching hand crosses behind the throwers back and withdraws the boomerang from behind the back).
Catch, Broken
A legal catch of any part of a boomerang is considered a legal catch if all other boomerang requirements are met.
Catch, Eagle
One hand clean catch during which the hand approaches the boomerang from the (overhand) top of the boomerang.
Catch, Foot/Leg
A legal catch during which the boomerang is caught with the feet or lower legs. The boomerang may not touch any part of the competitors knees, or anywhere above his knees. The boomerang and both of the competitors feet must remain clear of the ground during the catch. The thrower may elect to make a stand up foot/leg catch in place of the foot/leg catch.
Catch, Hackey
A catch where the first contact of the boomerang must be made with the foot, defined as any part of the body below the ankle. Either or both feet may be used. The thrower attempts to kick or “hackey” the boomerang off the foot, and then catch the boomerang prior to contact with the ground. After the boomerang has been kicked, any legal catch may be made, including body traps.
Catch, Legal
Act of stopping and obtaining full control of a flying boomerang after a legal throw provided the boomerang has not touched the ground during the flight or catch and provided its range is sufficient. Full control must be obtained before the boomerang is allowed to touch the ground. The boomerang may be trapped against the thrower on any catch for which a clean catch is not specified. A boomerang may be “popped or bobbled” but must not be allowed to touch the ground. Anything that protrudes beyond the planes of the top or bottom surfaces of the boomerang may not be used to assist in catching. Holes – whether open or closed – may also not be used to assist in catching. No devices – mechanized or otherwise – may be used to aid in catching a boomerang.
Catch, One Hand Clean
Legal catch with the additional requirement that during the catch the boomerang may not touch the competitor except on the hand and forearm of the specified side (left or right). The boomerang may not touch the thrower’s elbow.
Catch, One Hand Behind The Back
One hand clean catch that satisfies requirements of behind the back catch. Exception: the boomerang may touch the back or buttocks or back of legs during the catch, but trapping the boomerang (either flat or on edge) against any part of the body to obtain control is not allowed. If the boomerang is withdrawn after control is obtained it may touch the body – even forcibly – as long as control is maintained. If control is lost, it must be regained by the catching hand without trapping.
Catch, One Hand Under The Leg
One hand clean catch that satisfies requirements of under-the-leg catch. Exception: the boomerang may touch the leg, body or buttocks during the catch, but trapping the boomerang (either flat or on edge) against the leg or body to obtain control is not allowed. When the boomerang is withdrawn after control is obtained it may touch the body – even forcibly – as long as control is maintained. If control is lost, it must be regained by the catching hand without trapping.
Catch, Stand Up Foot/Leg
Legal catch during which the boomerang satisfies all the requirements of a foot/leg catch except one or both feet may be in contact with the ground during the catch. The thrower may not touch the ground with any part of his body other than his feet or shoes. The boomerang may be trapped between or come to rest on the throwers feet and/or legs between the ground and his knees. The boomerang cannot touch the ground or his knees, however.
Catch, Tunnel
Under-the-leg catch where both feet remain on the ground while the boomerang is being caught. Either or both hands may be used for the catch. If, at the moment of catch, the thrower’s catching hand/arm is under a leg but the boomerang has not yet passed under the leg the boomerang must be withdrawn under the leg to complete the catch. Control by the catching hand(s) must be maintained until the catch/withdrawal is completed.
Catch, Two Hand Clean
Legal catch using both hands. The boomerang may not any part of the body except the hands/forearms. It may not touch the throwers elbows.
Catch, Under The Leg
Legal catch during which the boomerang passes under a leg. If, at the moment of catch, the thrower’s catching hand/arm is under a leg but the boomerang has not yet passed under the leg the boomerang must be withdrawn under the leg to complete the catch. Control by the catching hand must be maintained until the catch/withdrawal is completed.
Catch, Unofficial
Catch which does not meet all the requirements of a legal catch. Not counted as a catch.
Catching Aid
Any characteristic of a boomerang, hand, or other object that provides a catching advantage. Some examples are:
- Chemical or mechanical (Velcro) adhesives applied to the boomerang, the thrower or his clothing
- Any extension to the throwers hand, arm, leg, etc.
- Any item thrown to intercept a boomerang.
Center Point
Point at center of bulls-eye from which the radius of all accuracy and range circles are measured.
Circle Judge
See Judge.
Competition Field
Area specifically reserved for the boomerang competition and specifically authorized for use prior to the start of the event. Parking and spectator areas, adjacent in-use sports fields, streets, and any other areas designated as off limits, before the start of the competition, are not part of the competition field. Adjacent public or private land is not considered part of the competition field.
Feat
Best recognized performance in an event which does not meet the more stringent requirements of a record.
Glove
Any hand covering which may provide protection for hands but may not be made to aid catching or throwing.
Ground
Point where the earth or its covering is firm enough to noticeably affect the linear or rotational motion of a boomerang in flight or during a catch. If any part of the boomerang clearly touches the earth or its covering during an attempted catch the catch is not counted.
Head Judge / Head Line Judge
Person responsible for fair conduct of all events included in a tournament. This includes interpreting the rules, organizing other judges and stewards, and recording of scores. The head judge may be the tournament director.
Head Spotter
Person responsible for the determination of the furthest point of travel in the distance event. The head spotter triangulates the locations recorded by the range stewards to determine the point of furthest travel.
He, His
Reference to the male gender and for the purpose of this rulebook includes the female gender.
Immediately
As soon as possible – even if it is necessary to interrupt an official conversation.
Individual Event
An event in which one thrower competes and the score obtained by the thrower is applied to that thrower alone. The score recorded by that thrower may not be applied to any other individuals.
Interference
Situation in which the flight of a boomerang is altered by contact with another person’s boomerang in flight, a person, animal or pre-designated obstruction. Interference occurs if a boomerang is caught or deflected by someone other than its thrower. Interference can be called if a thrower is prevented from getting to his boomerang for a catch by a person or animal. Interference may not be called if the boomerang hits ground before the alleged interference. Re-throw policy is defined in each event’s rules.
Intermediate
The middle level/class of competition. Between novice and advanced.
International Scoring System
The system by which USBA tournaments are scored where placing position equals scoring points. The overall tournament placings are determined by adding scoring points from each event. Order of finish is from least amount of points (first) to most points (last).
Judge
Person responsible for fair conduct of an event included in a tournament. This includes interpreting the rules, organizing other officials and stewards, and recording of scores. The judge may be the head judge, or an event judge designated by The tournament Director or Head Judge. A judge may not be the active competitor.
Mandatory Event
- No event is mandatory.The Tournament Director may choose any set of events for the tournament. Tournament directors are free to experiment with tournament formats that meet their localities needs. All other rules within this rulebook apply. For example Contestants’ rights remain unchanged, rules for changing the events or order of events remains the same, and the rules for the events described in this rulebook remain the same. For example, a typical individual tournament consists of Accuracy, Fast Catch, Endurance, Trick Catch / Doubling 100, Australian Round, and MTA 100. Other events may be added or the listed events may be omitted or substituted at the discretion of the Tournament Director. All the events must be conducted per this rulebook.
- An event that is required in order to complete a tournament.All mandatory events must be declared prior to the start of the tournament. For example, an individual tournament may consist of Accuracy, Fast Catch, Endurance, Trick Catch / Doubling 100, Australian Round, and MTA 100. The required events are Accuracy, Fast Catch, Endurance, Trick Catch / Doubling, and Australian Round. MTA 100 is an optional event and will be contested only if time permits.
Meter Circles
Lines marked the specified distance from the center point on the field.
National Championship
Tournament(s) where all national event champions and national overall champion are determined. All events should be contested at a single tournament unless the venue is determined to be unacceptable for a particular event (i.e. field is too small to contest long distance) and as a result, the event is not contested at the tournament. If a venue is deemed unacceptable, the national championship for that event may be awarded to another tournament.
National Event Champion
The winner of the event at a predefined tournament (National Championship). Events where a national champion is determined include Accuracy, Trick Catch / Doubling 100, Australian Round, Fast Catch, Endurance, MTA 100, and Long Distance. Other events may be added at the discretion of the USBA Board.
National Overall Champion

Obstruction
Any moveable person or thing that could potentially interfere with a boomerang’s flight or movement of the thrower and is within 10m of outermost range steward. For example, a spectator standing at the 55m line during Australian Round may be considered an obstruction as the outermost range steward is at the 50m line. A spectator standing at 65m line during Australian Round may not be considered an obstruction.
Official
Tournament director, head judge or person designated by either of them to help officiate in an event. Officials may be competitors or non-competitors
Optional Event
An event that is not required in order to complete a tournament. Any event that is not declared as a mandatory event is automatically an optional event.

President, USBA
President of the USBA or person designated for the appropriate task by the president.
Range
Outermost meter circle over which the boomerang flies – between when it is thrown from and when it begins its return toward the thrower.
Range Challenge
Notification of event judge by any competitor or event official that a throw was suspected to be short. Any throw for which sufficient range stewards are not used to evaluate range of the throw may be challenged. Once a challenge is made the suspect boomerang must be handed to the event judge as soon as possible after completion of the thrower’s turn. The boomerang may not be handed back to the competitor until range testing begins. If the owner or thrower is observed to be altering the balance of the boomerang by adding or removing weight, or by twisting or bending it, the boomerang is assumed to be too short and the thrower’s turn is scored accordingly.
Range Test
Test procedure during which the thrower attempts to show event officials that his range challenged boomerang has adequate range. The test is conducted as follows: Thrower makes 5 throws from 2m circle. All throws are checked and must have at least 20m range. Throws must be the same style and in the same general direction relative to the wind – in the opinion of the head judge – as the throws used in competition at the time of the challenge. The throws are considered short if the thrower refuses to submit his boomerang to the judge as soon as possible after it is challenged.
Record
Best tournament performances as defined in “Records.”
Referee
Person(s) designated to help judges make decisions about protests and penalties.
Re-throw
Throw taken to obtain score in lieu of score lost due to interference on a throw during a previous turn. May also be ordered by judge if original throw could not be properly scored. Re-throws are conducted and scored to ensure that the thrower cannot improve upon the best score possible for the turn at the time of the interference. Valid scores obtained in spite of interference may become official scores if re-throw fails to improve upon it – unless interference caused improved score in the original turn.
Round
A sequence in an event in which each thrower (all throwers) has an opportunity to have a specified number of turns. Turns may be in rotation with other throwers, consecutively, or simultaneously per event rules.
Score
The sum of points accumulated by a thrower or team in a single event, the time recorded by a thrower or team in a single event.

Throw, Legal
Throw of a boomerang from inside the center most circle for the event that satisfies range requirements of the event.
Throw On Command
Boomerangs must be thrown upon verbal command of official announcing the event. Thrower has at least 5 second to throw after the throw command is given. The thrower loses his turn if 5 or more seconds has elapsed since the throw command was given, the thrower has not thrown, and the thrower has been informed that he has lost his turn.
Thrower
A competitor participating in a boomerang event.
Tournament Director
Person who organizes and is generally responsible for a tournament, or person designated by him to fulfill certain duties. The tournament director determines events, order of events, and assigns head judge responsibility.
Turn
Thrower’s opportunity to perform in an event. The sequence of turns for all competitors is set for all events and competition circles before the start of the tournament. A turn begins when the previous thrower’s turn has been scored or any time thereafter when the event judge indicates that officials are ready. The thrower must make his throw within 20 seconds (guideline – timing not required) of the start of his turn unless otherwise advertised or announced before the start of the tournament. Extensions may be allowed by judges if done fairly and consistently.
Un-Scored Round
Round in which an official score could not be recorded because of interference, or because the judge could not properly score the round. Requires a re-throw.
USBA Record
The best performance by a USBA member in a USBA tournament or a tournament in which rules of the event are at least as restrictive as USBA rules.

6.6. Warm-up throws or range checks are not allowed from or over an active circle – except as required or allowed by event rules.
6.7. Warm-up throws are permitted in designated areas at designated times. Unauthorized throws for practice, warm-up, tuning, testing, or for any other reason are not allowed. Contestants caught making such throws lose the next turn in the event for which they are preparing.
6.8. The owner of an obstruction that another competitor wants removed from the competition field must remove the item as requested as soon as possible. The obstruction may be up to 10m beyond the outermost range steward. Obstacles 10m beyond the outermost range spotters are not required to be moved. Officials may not be moved.
6.9. Intentional interference will not be tolerated. If a judge determines that intentional interference has occurred, the contestant responsible will be disqualified from the event. The victim will be given the opportunity (or be required) to make a re-throw if appropriate.
6.10. If a Range Challenge is made by or against a contestant, the boomerang being challenged must be submitted to the event judge immediately after the challenge has been received. The boomerang must not be altered in weight or shape.
6.11. If interference, or confusion occurs during a throwers round, the thrower should continue and complete the round as well as possible. A protest may be filed at the end of the turn or end of the round.
7. Contestant Rights
7.1. Competitors may replace a boomerang at any time between flights during an event. If a boomerang is replaced progress of the event must not be slowed by more than 15 seconds or the turn may be lost.
7.2. Any contestant may challenge the range of another thrower’s boomerang by reporting it immediately to the circle judge. If it is not reported before, at or immediately after the completion of the flight the challenge will not be registered, and a range test won’t be conducted.
7.3. Any thrower may request removal of an obstruction on the field prior to his throw. The obstruction may be moved up to 10m beyond the outermost range steward. Obstacles 10m beyond the outermost range spotters are not required to be moved. Officials may not be moved. A throw that hits an obstruction is not interference unless it moved to within 10m of the outermost range steward during the throw.
7.4. Legal gloves may be used in any event.
7.5. Any protest must be lodged with the event judge at the time of the alleged infraction. It will be dealt with at that time if feasible.
7.6. Any act, occurrence, or judgment which causes an advantage or disadvantage to any contestant or group of contestants may be protested. No protest may be made in any event after the next competitors turn has begun.

7.10. If a contestant believes that a protest was handled unfairly by the circle judge he may register a complaint with the tournament director, head judge, the USBA President, or any combination thereof. Complaints made to the tournament director and/or head judge must be registered no later than 5 minutes after the completion of the awards presentation. Complaints made to the USBA President must be sent within 3 days of the conclusion of the tournament and be received within 7 days of the conclusion of the tournament. Complaints received after the stated time limits will not be acknowledged unless the protest deals with a mathematical error.
7.11. Any competitor who desires to have a copy of the tournament results may request one from the tournament director at registration or at any time within 14 days after the completion of the tournament. Tournament directors are must provide a copy of the results within 30 days of the completion of the tournament.
8. Tournament Details
8.1. Tournaments will be held on schedule if at all possible regardless of weather.
8.2. Compliance with these rules must be certified for tournament results or records to be recognized.
8.3. At least 5 minutes general warm-up time is provided before the start of each event. Each thrower may use this time for practice, warm-up, boomerang selection, tuning, eating, etc. – as he desires.
8.4. Throwing order for all competition circles is established by random drawing after the starting number for each event is determined, but before the start of the first event.
8.5. Judges may use any means available to determine how an occurrence should be judged – including help from witnesses that had a better vantage point than the judge. Clear, obvious or suspected rules violations should be brought to the attention of the official required to make the call immediately by any official who sees the violation. The official required to make the call will then make the call. Example: a range judge sees an obvious foot fault. He tells the center judge. If the center judge did not notice the throwers feet on the throw in question, he (officially) calls foot fault. If he saw that there was no fault, he overrules the range steward and announces that the throw was legal.
8.6. Re-throws are conducted according to the rules of each event so they do not create an unfair opportunity for any thrower to improve upon the score he could have obtained in the turn for which a re-throw is awarded. If a valid score was obtained during the turn in which interference occurred and it is better than the score obtained during the re-throw, it may be recorded as the official score – if appropriate.
8.7. Throw-offs may be used to break ties for tournament purposes if the procedure is announced before the start of the first event. THROW-OFFS DO NOT AFFECT OFFICIAL SCORES OR PLACINGS, however – except as required by event rules.
8.8. Officials for all events include the event judge, and scorekeeper. Additional officials required in each event are specified in each event’s rules.
9. Intentional Interference
9.1. If interference appears to be intentional on the part of the thrower (like intentionally hitting a range steward) the thrower is disqualified in the event.
9.2. If a competitor other than the thrower intentionally touches a boomerang in flight he will be disqualified in the event involved. The thrower will then be required or allowed to make a re-throw as appropriate whether he caught the affected boomerang or not.
9.3. If the judge considers the offense to be unusually serious on the part of the thrower or another competitor, the offender may be disqualified in the succeeding events(s) or the tournament, as appropriate. These actions may be made only with the consent of the tournament director, head judge and referee, however.
10. Protests
10.1. Must be resolved as quickly and fairly as possible – without disrupting the contest(s) unnecessarily.
10.2. Are ruled upon by the committee comprised of the tournament director, judge, and referee.
10.3. Are resolved immediately if possible – before the next event begins in any case. If this is not possible, officials must tell the protester when to expect a decision and the reason for the delay.
11. Timing
11.1. Any timer must disqualify his time if he did not start or stop his stopwatch at the right moment on any turn.
11.2. All timers time (official timers and alternate timers) each turn.
11.3. Method of timing:
11.3.1. Three timers plus one or more alternate timer (preferred method of timing)
11.3.1.1. If using multiple alternate timers, the order of alternates must be designated. For example, first alternate, second alternate, etc.
11.3.1.2. If an official timer disqualifies himself, the (first) alternate timer will become an official timer.
11.3.1.3. If the time difference between the shortest time recorded by an official timer and the longest time recorded by the official timer is less than or equal to 0.75s and no official timer disqualifies himself, the median time recorded by an official timer is the official time.
11.3.1.4. If the time difference between the shortest time recorded by an official timer and the longest time recorded by the official timer is greater than 0.75s, the three closest times including the (first) alternate will be considered. If the time difference between the shortest time recorded by an official timer or alternate and the longest time recorded by an official timer or alternate is less than or equal to 0.75s, the median time recorded by an official timer or alternate is the official time. This step may be repeated using all available alternates until an official time is obtained or all alternates have been used.
11.3.1.5. If all alternates have been exhausted and the difference between the shortest time recorded by an official timer or alternate and the longest time recorded by an official time or alternate is still greater than 0.75s, proceed as if using two timers.
11.3.2. Three timers
11.3.2.1. If an official timer disqualifies himself, proceed as if using two timers.
11.3.2.2. If the time difference between the shortest time recorded by an official timer and the longest time recorded by the official timer is less than or equal to 0.75s and no official timer disqualifies himself, the median time recorded by an official timer is the official time.
11.3.2.3. If the time difference between the shortest time recorded by an official timer and the longest time recorded by the official timer is greater than 0.75, proceed as if using two timers using the two closest times.
11.3.3. Two Timers
11.3.3.1. If an official timer disqualifies himself, proceed as if using one timer.
11.3.3.2. If the time difference between the two times is less than or equal to 0.50s and no official timer disqualifies himself the thrower has the option to accept either time as his official time.
11.3.3.3. If the time difference between the two times is greater than 0.50s proceed as if using one timer.
11.3.4. One Timer
11.3.4.1. If an official timer disqualifies himself, the thrower is given a rethrow.
11.3.4.2. If the official timer does not disqualify himself, the thrower may accept an official time lesser or greater than the time recorded by the timer by any amount not exceeding 0.75s.
12. Scoring
12.1. Individual and Team Tournaments
12.1.1. Official tournament size is the number of contestants or teams registered at the end of the start of the second event or second round if only one event is being contested. Sanctioned Tournaments must have a minimum of 11 competitors.
12.1.2. Scoring at the tournament is done according to event rules on the official scoring sheets. Scores are ranked and placing points are awarded in each event.
12.1.3. Placing points for each event are determined by using the International Scoring System
12.1.3.1. Ascending placement system: Lower points are better.
12.1.3.2. Placing point same as score. For example, first place receives 1 point, second receives 2 points, etc.
12.1.3.3. Worst score equals the total number of throwers or teams in the event
12.1.3.4. Non-scores or failure to compete in a given event equals the total number of throwers or teams in the event.
12.1.3.5. No additional points are given for winning an event
12.1.3.6. In the case of ties, all placing points occupied by the tied throwers or teams are added and divided by the number of tied throwers or teams. For example, if 3 throwers are tied for first place, 1 + 2 + 3 = 6 / 3 = 2 points for each thrower. The next thrower receives 4 points
12.1.4. Placing points for all events are added to determine tournament overall placing.
12.1.4.1. Ascending placement system: Lowest total points is first, highest total points is last.
12.2. Head to Head (H2H) Tournaments
12.2.1. Each event is a separate tournament.
12.2.2. Two (or more) throwers compete at the same time on separate circles.
12.2.3. Scoring on each circle for each event is done according to event rules on the official scoring sheets. The best score moves on to the next round.
12.2.4. Rounds are repeated until only one thrower remains. The last thrower is the Head to Head Champion.
13. Records
13.1. USBA Records
13.1.1. The USBA President is responsible for keeping the USA records up to date.

- Time of the record.
- Weather conditions at the time (temperature, wind speed, etc.).
- Field conditions (pertinent on or off field objects that may have affected the result).
13.1.7. Records set using a rule book other than the approved USBA event rule book will be evaluated prior to acceptance as a new USBA record. If the rules used to set the record are deemed to be equivalent or more stringent, the record will be accepted.
13.1.8. Individual records may be set either in individual competition or in team competition where individual scores are recorded. If claiming an individual record in a team event, the team on which the record was set must be a USBA Team or International Team.
13.1.9. Team records may be set in team events only. Teams claiming a USBA Team Record must be a USBA team.

Required for score:
– 20m range flight.
– Legal throw from inside the 2m circle.
– Legal catch(es) of types required in turn.
Tandem Throwing (Optional):
– Two (2) throwers throw in the same turn from the same 2m circle. The 2 throwers run alternately to save time. One (1) thrower throws from the 2m circle at a time. While 1 thrower competes, the other prepare to throw. The thrower not competing must be ready to throw 15 seconds after the other thrower in his circle has caught, has not caught, or gives up. As soon as the flight of the boomerang has ended and the score recorded, the 15 seconds begins.
– Throwing order is to be determined by throwers but must be maintained throughout the event.
– In the event of an odd number of throwers, circle judge will assign a non-scoring second thrower to the last thrower.
Tandem Throwing Interference:
– If a boomerang hits the thrower, the score recorded is 0. If a boomerang hits the tandem partner, the tandem partner receives a score of 0 for that throw, and the thrower must take a mandatory tandem re-throw.
Scoring:
– Throwers attempt 10 trick catches with a boomerang thrown singly. Then attempt 10 additional trick catches with boomerangs thrown simultaneously as doublers.
– Official score is the total of 15 (or more) throws.
– If a thrower scores a perfect score of 100 points, he will continue to throw the same 15 throws until he drops. During doubling, if he drops the first boomerang he attempts to catch, no points for a catch of the second boomerang of the doubling throw are given. His total score may accordingly be more than 100 points.
– The catches must be performed in the following order, and are worth the indicated number of points:
Single Boomerang Sequence
- Left Hand Clean2 points
- Right Hand Clean2 points
- Behind The Back3 points
- Under The Leg3 points
- Eagle Catch4 points
- Hackey Catch6 points
- Tunnel Catch6 points
- One Hand Behind The Back7 points
- One Hand Under The Leg7 points
- Foot Catch10 points
Single Boomerang Subtotal: 50 points
Doubling Sequence:
- Behind The Back and Under The Leg3 + 3 = 6 points
- Hackey catch and Left Hand Clean6 + 2 = 8 points
- Tunnel Catch and Right Hand Clean6 + 2 = 8 points
- One Hand Behind The Back and One Hand UnderThe Leg 7 + 7 = 14 points
- Foot Catch and Eagle Catch10 + 4 = 14 points
Doubling Subtotal 50 points
Total: 100 points
Round:
– The event includes 1 round of 15 (or more) throws for each thrower. Throwers may pass on throws. A passed throw will be score 0.
– If 2 throwers are throwing in rotation with each other, after the turn of the first thrower has been completed, the second thrower will be given a signal indicating the start of his turn. After the second thrower has completed his turn, the first thrower will be given a signal indicating the start of his turn. This process will be repeated until all the round is complete. Both throwers will be given enough time not to interfere with each other.
– In Doubling:
– The 2 required catches for each throw may be made in either order.
– If 1 boomerang is short, both boomerangs are considered short.
– The thrower must retain control of the first boomerang until after the second catch is completed. If the first boomerang is caught, then dropped prior to or during the second catch, the first boomerang does not count.
– The thrower may attempt a catch a second time in 1 doubling throw if the first attempt was not caught.
Warm Up
– No practice throws once the warm up is over.
– Each thrower, or group of throwers, has a 2 minute warm up in the 2m circle prior to the start of the round. The timed warm up starts as soon as the circle judge signals that the circle is clear. The thrower(s) may start their round prior to the completion of the 2 minute warm up if desired.
Re-throws
– Re-throws are made at the end of the round.
Officials per circle:
– May be competitors.
– 1 circle judge.
– At least 3 range stewards.
Notes:
– Due to weather or other conditions, the tournament director may decide to drop the doubling sequence which would result in Trick Catch 50. If a thrower scores a perfect score of 50 points he will continue to throw the same 10 throws until he drops. His total score may accordingly be more than 50 points.
14.5. Fast Catch
Timed Event
Best: Shortest Time
Circles:
– Contested on circles of 20m radius (which also contains 2m radius circle). See Figure 3.

– Time limit is 1 minute. If 5 legal catches are not made before the time limit has elapsed, the number of legal catches is the score. If the boomerang is in the air at 1 minute and then caught, the catch counts. If the catch is the 5th catch, the time is given as the score.
Scoring:
– Time from the release of the 1st throw to the moment when the thrower makes the 5th catch inside the 2m circle or touches the 2m circle if the 5th catch was made outside the 2m circle.
– Official score is the shorter time of the 2 rounds. If a time is not obtained, the official score is the higher number of catches made of the 2 rounds.
Round:
– The event includes 1 round of 2 turns for each thrower.
– At the signal of the circle judge, it becomes the next thrower’s turn. He has 15 seconds to make the first throw.
Warm Up
– No practice throws once the warm up is over.
– Each thrower has a 1 minute warm up in the 2m circle prior to the start of the round. The timed warm up starts as soon as the circle judge signals that the circle is clear. The thrower(s) may start their round prior to the completion of the 1 minute warm up if desired.
Re-throws
– Re-throws are made at the end of the round for the thrower’s group. If a re-throw is required on the first round the re-throw must take place prior to the second round.
Officials per circle:
– May be competitors.
– 1 circle judge.
– At least 3 range stewards.
– 3 official timers (may be center judge or range stewards). More timers may be used but are alternates and official only in the event of a timing error by one of the 3 official timers.

– Each thrower has a 1 minute warm up in the 2m circle prior to the start of the round. The timed warm up starts as soon as the circle judge signals that the circle is clear. The thrower(s) may start their round prior to the completion of the 1 minute warm up if desired.
Re-throws
– No re-throws unless it is impossible to obtain a fair score of the original round, or unless interference results in a delay during the round of the thrower involved as indicated below.
– The problem in the original round must be serious enough to stop the round. Simple interference, such as hitting a range steward, is not sufficient grounds for a re-throw.
– If interference occurs, the turn and the round must be continued as well as possible. A protest may be filed after the 5 minute round has been completed.
Officials per circle:
– May be competitors.
– 1 circle judge.
– At least 3 range stewards.
– 2 official timers (may be center judge or range stewards). One timer is a backup.
Notes:
– If an injury occurs, the circle judge stops the round when he recognizes that the injury is serious. The timers stop the stopwatch with the STOP function and the circle judge announces that the round has been suspended due to injury. When throwing resumes, the timers restart the stopwatch as the thrower goes to recover his boomerang from where it was when time was stopped and resumes his round.

14.12. Long Distance
Distance Measured Event
Best: Farthest Distance
Circles:
– 2m circle. See Figure 6.
– 40m baseline centered in 2m circle. The baseline is a movable straight line (rope, chain, etc.) that has its middle on the center point. The 2m circle is cut in half by the baseline. The end of the baseline is marked on each end with a post. The baseline should be approximately perpendicular to the wind. The baseline may be adjusted at the request of the thrower prior to each throw. The baseline must remain straight at all times during the throw.
Required for score:
– 50m flight range.
– Legal throw at least one foot touching or within the 2m circle at point of release.
– Thrower may not cross the baseline at any time while the boomerang is in the air unless permitted to do so by the head line judge.
– Boomerang must cross the baseline upon return either directly or indirectly (from behind) without being touched or hitting anyone or anything.
– No catch required.
Scoring:
– Official score is the thrower’s longest scoring throw.
– Distance is measured in integer meters only (no centimeters) from the center of the 2m circle to the point in its flight farthest from the center point.
– Distance may be measured with either a steel measuring tape or laser range finder. If using laser range finders, one or two may be used. If using 1 laser range finder, it is to be operated by the head line judge. If using 2 laser range finders, one laser range finder will be with the head line judge and the other with the head spotter. If the distances measured are within 1 meter of each other, the distance scored is the distance measured by the head line judge. If the distances measured differ by 2 meters, the average of the 2 measurements will be recorded. If the distances measured differ by more than 2 meters, the distance will be remeasured until they are within 2 meters of one another or remeasured using a steel measuring tape.
Round:
– The event includes 1 round of up to 5 throws by each thrower.
– Throwers may adjust the orientation of the 40 meter baseline and spotters in the field once immediately prior to each of their throws (excluding warm up). The baseline may not be adjusted while the boomerang is in flight. The baseline orientation should be approximately perpendicular to the wind direction and should normally not exceed 45 degrees off wind as judged by the head line judge unless approved by a majority of competitors.
– When the thrower and head line judge are satisfied with the orientation of the 40 meter baseline, and the position of all other officials and spectators (for safety), the head line judge will declare the circle clear and it becomes the next thrower’s turn. The thrower must throw within a predetermined time limit (not less than 15 seconds) set prior to tournament or forfeit their throw.
– Each turn is completed by all throwers in the group in rotation before the next turn is started.
– Throwers in each group make 1 throw per turn – in rotation with other throwers in the group – until all throwers in the group have completed their round. The next group begins its round.
– Multiple rounds may be contested.
Warm Up
– General warm up may take place prior to each round. No time limit.
– Up to 3 practice throws may be made immediately prior to each group’s round.
– No practice throws for a thrower after their group’s round has begun.
Re-throws
– Re-throws are made at the end of the event for the thrower’s group.
Officials:
– May be competitors.
– 1 head line judge.
– 1 head spotter.
– 2 pole judges.
– 6 range stewards.
Notes:
– Safety
– Ensure all spectators are at a sufficiently safe distance.
– All spotters are watching when the boomerang is thrown and warn others if necessary.
– All spotters are standing while the boomerang is in flight.
– Only one long distance boomerang in the air at a time.
– No throwing when a thrower is retrieving a boomerang.
– Range Spotter Placement
There are a number of range spotters on the field to determine the point of return (furthest point of the boomerang’s flight path). You have to be aware that if the boomerang is more or less flying over you, it is difficult for you to judge where the projected path on the ground actually is. Only by spotting from a distance off to the side are you able to determine the apex of the flight path accurately. Therefore, we suggest placing a row of range spotters to the left and right of the expected throwing corridor with a 20-meter distance between the range spotters within one row. You can also align the 2 rows in a staggered manner to get a better coverage. The range spotters should be spread such that all throws, including the shortest and furthest ones, can be precisely spotted. Send the furthest range spotter sufficiently far out, as there may always be “lucky” throws. One of the head spotter’s duties is to ensure that the range spotters are distributed correctly.
Don’t use more range spotters than necessary to do the task, because with too many range spotters on the field they tend to walk about and have chats! 6 range spotters plus 1 head spotter is the minimum. 12 should be enough in all cases.
– Range Spotter Duties
Follow the boomerang on its way out with your extended arm and stop when you think it reached its furthest point. Then project that point down onto the ground by lowering your arm vertically. Fix the point on the ground with your eyes and direct the head spotter to that point. At least 1 other range spotter will do the same, so the head spotter will have to position himself such that the closest 2 – 4 range spotters are happy with the result. Often, there is a little conversation about the furthest point, but that’s the interesting part of spotting: talk until there is an agreement! The range spotters that could not see the apex of the flight path perfectly should not interfere! The maximum distance of the boomerang is now defined as the distance from the head spotter to the center of the throwing circle. If you have a Laser Rangefinder (for example, a Bushnell) you can measure the distance immediately, otherwise you have to place a marker in the ground and measure the distance at the end of the round with a steel tape.
Estimated accuracy of the measurement with this spotting method: 2m in the best case, 5m average, and worse if the range spotters are not placed very well or if they are not paying attention. Helpful idea: distribute thin wooden sticks (about 2m long) to the range spotters, with the help of which it is much easier to follow the flying boomerang to its furthest point and then drop them to the ground.
14.13. G-L-O-R-P
The boomerang game G-L-O-R-P is the same as the basketball game H-O-R-S-E. The first thrower does a trick catch and all the other throwers must do the same catch to avoid getting a letter. If you get all five letters you are out of the game. Last thrower left without G-L-O-R-P is the winner.
The first thrower (the Dominator) performs any trick catch of his/her choosing (except a Two Handed Catch) and then all the other throwers, in their assigned order, throw and attempt the defined catch. If they do not complete the defined catch they get their first letter. If the Dominator continues to perform trick catches, he continues to be the Dominator. When that Dominator drops, the next thrower becomes dominator. This continues until one thrower is left without G-L-O-R-P. He is the winner.
Clarification:
- The same catch cannot be done twice in a row, but a thrower can do an identical catch to one he has already done as long as it is not done back to back;
- When a new Dominator takes over, he cannot perform an identical catch to the last catch the previous Dominator completed;
- If a Dominator does a Two Hand Catch, or attempts a trick catch that he does not complete, but does not drop it, it is called a Pass. On a Pass, all the other throwers must catch the boomerang to avoid getting a letter, but the first thrower to do a trick catch, captures domination, and becomes Dominator. The pass has ended.
Three Tier Play
In keeping with the Team Gel spirit, it is radder to play boomerang games that include all levels of throwers. G-L-O-R-P can be played with three distinct skill levels: beginner, novice and expert.
When a Dominator defines a catch and it becomes a thrower’s turn to perform the catch, he may decide at which level he would like to play. If he decides to play as a beginner, he is required to only touch the boomerang to avoid getting a letter; If he decides to play as a novice, he is required to only perform an “any catch” to avoid getting a letter; If he decides to play as a expert, he is required to perform the Dominator’s trick catch to avoid getting a letter. When it becomes a novice’s turn to be Dominator, he must perform an “any catch” to retain Dominatorship. He may then make up the catch for the rest of the participants. When it becomes an expert’s turn to be Dominator, he must perform a trick catch to retain Dominatorship.
Judging Catches- The Honor System
Each thrower is responsible for judging whether or not he made his own catch as defined by the dominator. Each thrower is responsible for the integrity of his score and catches and must track his own score.
Dan Quayle “E” Rule
Throwers may add an “E” letter to spell GLORPE only once in their lifetime.

– Where he was whenever he touched the boomerang.
– Where he was when he completed the catch.
– Where the boomerang came to rest.
– If a contestant fall down after the catch is completed, location of his feet ( or last contact of body to ground) before his fall determines his location.
– If he is touching the ground when the catch is made, accuracy points are based on the location of all points of contact with the ground.
– If a contestant is not touching the ground when the catch is made, accuracy points are based on the first single point of contact with the ground after the catch.
Scoring Distance:
– Distance points are awarded only if accuracy or catching points are earned on the throw:
– 50m range or more: 6 points
– 40m range but less than 50m: 4 points
– 30m range but less than 40m: 2 points
– 20m range but less than 30m: 0 points
Scoring:
– The sum of accuracy, catching, and distance scores will be the score recorded for each throw. The maximum score for a single throw is 20 points (10 accuracy points, 4 catching points, and 6 distance points).
– Individual throwers score is the total of 5 (or more) throws.
– Official score is the sum of all competing team members individual scores.
– If a thrower scores a perfect score of 100 points, he will continue to throw until a throw with a total score of less than 20 points is obtained.
Round:
– The event includes 1 round of 5 turns for each thrower. All throws are scored (no optional throws).
– Contestants throw in as many groups of 6, 8, or 10 (3, 4, or 5 pairs of tandem throwers).

Points awarded
Best: Most Points
Circles:
– Contested on circles of 20m radius (which also contains 2m radius circle). See Figure 3.
Required for score:
– 20m range flight.
– Legal throw from inside the 2m circle.
– Legal catch(es) of types required in turn.
– Two (2) throwers throw in the same turn from the same 2m circle. The 2 throwers run alternately to save time. One (1) thrower throws from the 2m circle at a time. While 1 thrower competes, the other prepare to throw. The thrower not competing must be ready to throw 15 seconds after the other thrower in his circle has caught, has not caught, or gives up. As soon as the flight of the boomerang has ended and the score recorded, the 15 seconds begins.
– Throwing order is to be determined by throwers but must be maintained throughout the event.
Scoring:
– Throwers attempt 10 trick catches with a boomerang thrown singly. Then attempt 10 additional trick catches with boomerangs thrown simultaneously as doublers.
– Individual throwers score is the total of 15 (or more) throws.
– Official score is the sum of all competing team members individual scores.
– If a thrower scores a perfect score of 100 points, he will continue to throw the same 15 throws until he drops. During doubling, if he drops the first boomerang he attempts to catch, no points for a catch of the second boomerang of the doubling throw are given. His total score may accordingly be more than 100 points.
– The catches must be performed in the following order, and are worth the indicated number of points:
Single Boomerang Sequence
- Left Hand Clean2 points
- Right Hand Clean2 points
- Behind The Back3 points
- Under The Leg3 points
- Eagle Catch4 points
- Hackey Catch6 points
- Tunnel Catch6 points
- One Hand Behind The Back7 points
- One Hand Under The Leg7 points
- Foot Catch10 points
Single Boomerang Subtotal: 50 points
Doubling Sequence:
- Behind The Back and Under The Leg3 + 3 = 6 points
- Hackey catch and Left Hand Clean6 + 2 = 8 points
- Tunnel Catch and Right Hand Clean6 + 2 = 8 points
- One Hand Behind The Back and One Hand Under The Leg 7 + 7 = 14 points
- Foot Catch and Eagle Catch10 + 4 = 14 points
Doubling Subtotal 50 points
Total: 100 points
Round:
– The event includes 1 round of 15 (or more) throws for each thrower. Throwers may pass on throws. A passed throw will be score 0.
– The 2 throwers throw in rotation with each other. After the turn of the first thrower has been completed, the second thrower will be given a signal indicating the start of his turn. After the second thrower has completed his turn, the first thrower will be given a signal indicating the start of his turn. This process will be repeated until all the round is complete. Both throwers will be given enough time not to interfere with each other.
– In Doubling:
– The 2 required catches for each throw may be made in either order.
– If 1 boomerang is short, both boomerangs are considered short.
– The thrower must retain control of the first boomerang until after the second catch is completed. If the first boomerang is caught, then dropped prior to or during the second catch, the first boomerang does not count.
– The thrower may attempt a catch a second time in 1 doubling throw if the first attempt was not caught.
Warm Up
– No practice throws once the warm up is over.
– Each pair of tandem throwers has a 2 minute warm up in the 2m circle prior to the start of the round. The timed warm up starts as soon as the circle judge signals that the circle is clear. The throwers may start their round prior to the completion of the 2 minute warm up if desired.
Re-throws
– Re-throws are made at the end of the round.
Officials per circle:
– May be competitors.
– 1 circle judge.
– At least 3 range stewards.
Notes:
– Due to weather or other conditions, the tournament director may decide to drop the doubling sequence which would result in Trick Catch 50. If a thrower scores a perfect score of 50 points he will continue to throw the same 10 throws until he drops. His total score may accordingly be more than 50 points.

Head Judge Nominees:
USBA Aesthetic Rules 2015
These rules are to be incorporated into the USBA Official Rule book and used for judging the Aesthetics Competition at the USBA National Tournament and Exposition.
The National Tournament Director will appoint an Aesthetics Coordinator to discharge all aspects of the Aesthetics Competition. The Aesthetics Coordinator will appoint a Judging Panel. The Aesthetics Coordinator will set up a process to receive entries from those unable to attend Nationals.
Judging Panel must consist of three judges who are active throwers, craftspeople or both. Judges may not have any items entered in a competition for which they are judging. In the absence of three judges, voting shall be done by anonymous ballot by those in attendance at USBA Nationals.
Those wishing to enter items in the competition must be current paid USBA members. In the event a group (such as students) wish to enter a collaborative object, one person must be a paid USBA member to enter.
Divisions/Classifications for Awards will consist of Mechanical Design, Decoration, Craftsmanship and Natural Elbow for boomerangs. A separate category will be judged for both throw sticks and boomerang related objects, such as bull roarers, t-shirts, etc. Each category will have a 1st, 2nd and 3rd Place. A category for Over-All Crowd Favorite will also be awarded 1st-3rd Place and this category will always be voted on by USBA members in attendance at Nationals, whether judges are used or not. This award will come from all items entered into the Aesthetics competition. All objects entered in the competition must have clear designation (whether inscribed on the object or affixed to it) of name and contact info. A category for the entry may be suggested by the entrant. However, separation of Aesthetic entries into categories may be selected or changed by the judges or the Aesthetics Coordinator, and any change of this sort may not be disputed. Any boomerang entered into the competition is attested to be a flying returning boomerang. If the judges feel there is credible evidence that an entry designated a boomerang is in fact not capable of returning, then the judges can ask permission to test said boomerang or, at their discretion biding the inability to test or a wish not to as for potential of causing harm to entry, the judges may place said object in the Boomerang Related Object category.
Definitions for the categories are as follows:
- Boomerangs: Any style past or present that when thrown precesses and returns to thrower.
- Mechanical Design: A boomerang whose design (structure or manufacture) is new or that attempts to incorporate old or standard flight characteristics in a new way.
- Decoration: paint, appliqué or attached materials applied to the boomerang.
- Craftsmanship: Strip lamination, lap joint or other construction processes that emphasize technique and manufacturing prowess of materials, wood or otherwise.
- Natural Elbow: Boomerangs constructed from roots or limbs of trees or other organic structures where the curve of the boomerang is already in existence.
- Throw sticks (Kylies): Any object constructed from natural or man made substances that is designed for non-returning flight.
- Boomerang Related Objects (Bull Roarers, t-shirts, etc.): Any object d’Art that incorporates boomerangs or is related to boomerangs by culture or that has a boomerang theme.
There is a limit of two entries per category or seven entries total from any individual. Objects entered into the competition are understood to be the property and work of the person entering them. If a person enters someone else’s work, whether on another person’s behalf or as owner of said object, the judges may require documentation that the person entering the object has permission of the originator to do so and any award will be given to the person who performed the work, although it may be received by the person submitting the work. Any collaborative object that wins or places will be noted as a win or place for the group responsible for the work, not just the individual who entered the object. Any entry that wins or places (1st – 3rd in any category) is ineligible to be entered into any future National Aesthetics competition. However, objects that do not win or place may be re-entered after a period of three (3) years.
The Aesthetics Coordinator will see that individual photos are taken of all entries to assist in public relations and notification of winners.
