W1 / W2 Support Craft

Official and Support boats must consist of a minimum of three (3) boats, with the remaining craft to be made up of any combination of boats or jetskis (jetskis must have as a minimum an attached sled, radio communication, and a driver and 1 crew).

W6 / WT12 Support Craft

Only one (1) jetski with an attached sled may form part of the support boat numbers
