There are numerous categories that define the levels of competition for inshore powerboat racing. Much like circuit car racing, the highest levels are designated "Formula" followed by a number, and the principal of these is the

. Each "Formula" level follows a different set of regulations that specify the design of the boat and engine, as well as the rules of competition. 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. Races will vary in duration, normally no more than 45 minutes, but endurance category races can last much longer, such as the "24 Hours of Rouen". Historically, powerboat racing has been defined by 'classes' and this is still the case in offshore powerboat racing where Class 1 is the premier category. For inshore racing, up until the creation of Formula 1, the OZ, ON, and OE classes were regarded as the most prestigious categories. The following Formula categories are currently sanctioned by the UIM: * Formula 3 is one of many defunct "Formula" categories; it was cancelled after 2004. Brodenbachstart

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.
