Sorry for the delay, had a computer issue that I was battling yesterday, and most of today.. Finally got it fixed. (Blue Screen Blues, and it wouldn't open a PDF)
DIVISION 1: "FACTORY INBOARD SKI & PERFORMANCE"
New for 2015, Division 1 is now a bracket class intended for both pleasure and performance boats that run in the 55-75 mph range. The maximum speed for this division is limited to an 11-minute lap time over the 12-mile course. This equates to an average speed of around 65.5 mph. If a Division 1 boat records a lap faster than 11:00 minutes, then the current lap will not count as completed. If a driver has 3 or more violations and the referee deems him unsafe a black flag will be shown to the driver and he will be required to trailer the boat and face penalty.
HULL: Any type of boat is allowed. Minimum length is 16 feet, measured from bow to transom of the hull (excluding external engine set back). Maximum length is 22 feet. Weight is unrestricted unless a boat is deemed too heavy, causing large wakes.
ENGINE: Inboard internal combustion only. No Turbine.
DRIVE: No surface drive allowed.
