The watercraft has a straddle-type motorcycle-like seat on which passengers may sit in straddle/tandem fashion and an engine. The major portions of its exhaust system are disposed beneath this seat. The exhaust system is centralized in the watercraft to maintain side-to-side balance, and a portion of the seat is removable for accessing the engine.
