Bathtub Racers’ Rules
IMPORTANT NOTICE TO ALL CONTESTANTS
These are all the official safety and design rules that form the basis of the events we will run in the Bay of Islands each year. They are designed to give tub builders the freedom to have flair and imagination in their design while working within some broad standards. The whole idea is to have fun with as few rules as possible, however, with safety for all being of paramount importance, the rules must be followed and failure to do so by any person/s may result in disqualification.

- All protests must be made within 30 minutes of the results being posted.
- Protests against the rules or eligibility of an entry must be lodged before the drivers’ briefing, otherwise within half an hour of the posting of results in which the incident or circumstance occurred.
All participants agree and accept that:
- Bath tub racing may be hazardous and they enter at their own risk.
- Whilst the organisers or any other persons involved with the event have taken every precaution to ensure the safety of the competitors they will not be held responsible for loss or injury incurred by any person or to any equipment.
- The BOIB Committee reserves the right to disqualify any Tubber.
- Any competitor suspected of or appearing to be under the influence of drugs or alcohol will be prevented from racing.
- All Tubbers must follow the instructions of the race controller at all times. All Tubbers must take action to avoid collision.
- STARTS: The type of start for your race will be weather dependent and determined by the Committee. You will be advised of start formats at the pre-race briefing.
Audible or visual signals at 30 seconds.
WHITE start flag is raised for between 5 and 12 seconds. The start is signalled by lowering the WHITE flag.
An aborted start is indicated by raising a RED flag.
The starts will be fully described by the race controller at the driver’s briefing.Note: Any competitor will be disqualified from their heat for more than one early start.
- OVERTAKING PROCEDURE
Overlap: Is only established when two Tubs are approximately on the same course and the cockpit of the overtaking Tub must be overlapping the cockpit of the overtaken Tub. The overtaking Tub may not create the overlap outside of the set course while overtaking.
Overtaking: An overtaking Tub MUST NOT cut in front of an overtaken Tub until a minimum distance of 1/2 a Tub length is established.
If two or more Tubs are approaching a turn mark side by side, the Tub on the inside of the turn has priority and the outer Tub/s must give water and hold racing lines.
Dangerous driving e.g. not holding race lines, intentional throttling back in front of overtaken Tub, snaking and blocking will result in disqualification or penalty at the discretion of the race controller. A Tub must not bear out of its course as to hinder another in passing to the outside.
If any Tub collides mid-ships with another (T-bone) this will result in immediate disqualification of the offending Tub from that race.
- TURN AND COURSE MARKS OF THE COURSE
Hitting a turn mark – no penalty
Missing a turn mark – penalty (concede gained place)
Travelling against the racing line – disqualification
Where two turn buoys are positioned at a mark, no racing penalty for hitting, dislodging, damaging or destroying one of the buoys.
Where there is only one turn buoy – either because there was only one laid in the first place or because one has been taken out – disqualification or penalty will apply for dislodging, destroying or so damaging the remaining turn buoy that it is no longer viable.
- TUBBER IN WATER
When a driver is in the water on the race circuit the race is stopped immediately.
If the driver is fit and well following an accident or breakdown they should attempt to indicate that they are not injured. If they are injured, they should sit and wait for the rescue personnel to stop the race.
By passing the chequered flag, or as described at the drivers’ briefing .
When the winner of a race is determined all other competitors will finish on the same lap as the winner regardless if they are laps behind.
- AFTER FINISHING
After finishing, drivers must slow down, must not cross the course, must not take extra laps or other practice, and must carry on round the course away from other finishing drivers and enter the pits in accordance with local instructions.
- FLAG SIGNALS
RED FLAG – Slow down/stop immediately and proceed with caution to the designated area as described at drivers briefing.
