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. A platform is pivotally connected to the underwing forward end and/or rearward end and conforms to the pontoons at their forward tapered end or their rearward end, respectively. A power assembly is connected to the platform for 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 raising or lowering the platform back to the stowed position. For protecting the craft from damage, the platform also can carry a deployable extending ramp formed from a pair of spaced-apart floating pontoons with a walkway extending between the floating pontoons. A novel fendering system for the craft also is disclosed.
