This 2004 West Bay Sonship is a 58-foot composite motor yacht powered by twin MTU Series 60 diesel engines producing 825 horsepower each, with electronic controls and Twin Disc transmissions. She cruises at 16 knots and reaches 23 knots at full speed. Built using fiberglass infusion and vacuum bag technology with 316L stainless steel and frameless windows, the yacht combines Dutch craftsmanship with practical offshore design.
The accommodations span three staterooms and two heads. The full-beam primary suite amidships features a queen berth, ensuite head with shower, washer and dryer, and abundant storage. Forward is a VIP stateroom with queen island berth and ensuite access, while a third stateroom with over-under berths serves guests or crew. The main living spaces include a full-beam salon with satin-finished American cherry joinery, an open galley with granite countertops and quality stainless appliances, and a raised pilothouse that doubles as a social hub. An enclosed flybridge with hardtop and four-sided enclosure provides an upper helm and lounge area.
Navigation and engineering systems are extensive: dual helm stations with three 17-inch Furuno NavNet displays, Simrad autopilot, VHF radio, and integrated cameras. Twin Northern Lights 12-kilowatt generators, twin 500-gallon fuel tanks, Wesmar hydraulic stabilizers, bow and stern thrusters, and comprehensive climate control including reverse-cycle heat and air conditioning across four zones support extended cruising. Recent 2025 improvements include complete engine and generator service, new hot water tank, replaced trim tab motor, and professional HVAC servicing.
An AB 12-foot tender with 40-horsepower Yamaha outboard and Steelhead hydraulic davit are included, along with fish-finder, downriggers, fish-cleaning table, and bait tank—equipment reflecting both entertaining and fishing capability from the teak aft deck and swim platform.
