In the process of evaluating equipment (re-) registration applications for the 2024 Olympic Cycle, the IKA Technical Committee has become aware of discrepancies in the dimensions of the Mikeslab Bullet 3L / 3LC foil.
The dimensions provided by the manufacturer for the re-registration of the equipment differ from the dimensions of the same equipment registered in May 2017, with several of the dimensions provided with the re-application being outside of the accepted tolerances.
Unfortunately, the manufacturer did not provide the IKA with information on when these dimensions may have changed, and which parts and serial numbers may be affected.
In order to protect competitors and teams from travelling to events with equipment that may not comply with the registered dimensions and therefore the Formula Kite class rules, competitors in possession of a Mikeslab Bullet 3L/3LC foil should verify that their equipment complies with the class rules and the registered dimensions.
The registered public dimensions, including allowed tolerances, are:

Mikeslab Bullet 3L / 3LC foils with different dimensions (including tolerances) are not eligible to compete in Formula Kite events. The same principle applies to all Formula Kite registered series production equipment.
Competitors are reminded that according to the Racing Rules of Sailing, it is ultimately the responsibility of each competitor to ensure that their equipment complies with the class rules (see RRS 78).
