GY21 Amphibious Catamaran
Yet another amphibious boat designed for a keen New Zealand diver.
The 6.52m Catamaran, is designed to be built from marine grade aluminum alloy.
As a day diving boat and taking a lots of gear on board the design brief was for a large cockpit (3.36m length X 2.145m wide).
The cockpit floor is fully welded and provides watertight compartments in both hulls. Its level is above the water surface which makes the cockpit self-draining (thru 2 large transom mounted spring loaded scuppers).
There are also 2 watertight bulkheads in each hull.
This amphibious catamaran is capable to be driven on tidal and soft sand.
Beam: 2.50 m
Draught (engine up) 0.33 m
Weight-dry boat: 1600kg
Engine: outboard 225-250 hp
