Twin Caterpillar C18s (1001 BHP) coupled with Hamilton HJ403 water-jets will give a top speed of 36 knots and cruising speeds in excess of 30 knots. Construction is infused FRP composite with CoreCell PVC foam core. Water-jet propulsion means that this vessel will have an operating draft of approximately three feet, or roughly one and one-half feet less than a propeller-driven yacht of comparable size and type.

Accommodations include an owner's cabin with en-suite head and an office which converts to a guest cabin, also with its own head. The spacious, near-flush aft deck conceals a tender garage which accommodates an 11-foot RIB.
