This model has a control station on the upper deck for Captain and crew in place of the lower helm station. It also offers the option of an aft upper deck for passengers. The design offers extensive flexibility in layout, allowing for a range of use, ranging from tour, whale watching, diving, snorkelling, game fishing etc. Power options range from twin 315 HP inboard diesels to twin 500 HP, providing the speed needed.

The superbly designed hulls offer a comfortable ride with the economy that only a well designed catamaran can provide for up to 60 passengers
