Abstract

A catamaran has a pair of spaced-apart pontoons, each having a forward tapered end and a rearward end. An underwing is affixed to the pontoons and spans therebetween. The underwing has a forward end and a rearward end. A platform is pivotally connected to the underwing forward end and/or rearward end. The platform also has a forward end. A power assembly (e.g., oil hydraulic, air hydraulic, cable lift, chain lift, spring loaded, gear-driven, and other lifting mechanisms) is connected to the platform for one or more of lowering or raising the platform from a stowed position to a plurality of working positions—including positions below the waterline—of the catamaran and for one or more of raising or lowering the platform back to the stowed position.
