The Comp Jet (CJ) class has quickly become a very popular Inboard Endurance choice. Virtually any hull up to 24 feet long with two stringers may run in the class.

The engine is to be located forward of the jet drive, and the driver must be seated forward of the engine. This is a great way to get into the thrilling world of Inboard Endurance racing.
