This vessel is a production-built West Bay SonShip 72 motor yacht. The hull is a hard-chine design with moderate deadrise, a shallow ¾ length keel, a raked and flared bow, and a plumb transom stern fitted with an integral boarding platform.
There is a roomy foredeck fitted with an anchor platform and a chain locker, followed by ample side decks leading aft on either side of a low-profile trunk cabin to a raised pilothouse with entry doors to port and starboard. The side decks step down aft of the pilothouse and then lead aft on either side of the main cabin to another step-down at the roomy aft deck. The aft deck features an upholstered, slightly curved bench seat with pedestal table aft, double metal-framed glass entry doors forward on centerline with a cabinet outboard to port and a docking station in the fashion wings to port and starboard. A ladder to starboard of the entry doors leads up through a companionway hatch to the boat deck and flying bridge. Hinged boarding gates are fitted to port and starboard outboard with steps leading down to the boarding platform and transom. The transom is fitted with a watertight door on centerline accessing the crew quarters and engine room. The aft deck is overlaid with teak. Stainless steel rails surround the decks and stainless steel staple type rails are fitted across the aft end of the boarding platform.
