摘要

The boat has a jet drive (2) with a uniform structure. A function module (1) combines an entire drive technique, an energy supply, and receiving and control technique. A plug, a cable, a ruder, a shaft and battery are not attached on a hull. The function module is inserted in or on the hull. The function module is completely independently functionable. A pressure chamber is limited by a boat body by a circular sealed contact surface with the function module, where the contact surface serves for sealing and center of gravity displacement purposes.
