The most common form of inshore powerboat racing involves a race around a two pin (buoy) or multi-pin circuit of approximately 1.5 – 2 km in length. Each pin marks a turn in the course.

Boat designs

Many inshore championships utilise variations on the catamaran style boat design, particularly the higher levels of the sport. In lower categories however, different designs are utilised which are determined by the class regulations. In these instances, traditional V hulls and inflatables are common and are the accepted way for younger pilots to gain experience and progress through to the more powerful catamarans.
