The 86-foot West Bay Sonship is a pilothouse motor yacht built in 2003 with a 20-foot beam. Her composite hull uses Core-Cell technology and a modified-V design, built with vacuum bag methods and 316L stainless steel hardware. Twin Detroit MTU 12V2000 engines produce 2,960 horsepower combined, delivering a cruising speed of 12 knots and a top speed of 27 knots, with an approximate range of 1,450 nautical miles.
The yacht accommodates up to eight guests across four cabins and four heads, with dedicated crew quarters. The layout provides both private stateroom space and areas suited to entertaining aboard.
The yacht received an extensive refit in 2026, including comprehensive servicing and upgrades throughout. Her design reflects the Dutch-influenced proportions characteristic of the West Bay Sonship line, with a commanding running profile suited to extended Pacific Northwest cruising and coastal passages.
