What have they got to do with TriloBoats?
The PD bottom profile is compatible with TriloBoat upper hull and plan view specifications. New classes of PD Racers are open for definition by whomever completes hull #1. All that is required is that they be scale variations of the original PD Racer proportions (length, breadth and height may each be scaled independently). Visit www.pdracer.com/variants for the rules for declaring a new class of PD Racer. This means that you could slap a scaled bottom profile onto any Triloboat size and define a new PD racing class. Or, if someone has already defined the class, you can build to their specs and race them, head to head.
