Abstract
A catamaran vessel with hybrid propulsion engines for driving propeller propulsors and pump-jet propulsors. The vessel includes two side hulls and a mobile platform that can be moved between upper and lower positions relative to the side hulls to accommodate navigation conditions. The engines are selectively coupled to the propeller propulsors, the pump jet propulsors, and control mechanisms changing the position of the mobile platform-between the upper and lower positions.
