The vessels, MV Sally Fox and MV Doc Maynard, are two ferries operating for King County’s Marine Division as replacement vessels for their scheduled water taxi service. Sally Fox is the first U.S. Coast Guard Sub-chapter “K” inspected passenger vessel built and delivered under the new 5A Space Performance Guidelines issued in a Memorandum regarding NVIC 9-97 Ch-1. The Memorandum is a result of the Quality Partnership working group between the U.S. Coast Guard and the Passenger Vessel Association. The new 5A Space Performance Guidelines make it possible for boat builders to design and implement suitable structural fire protection in very low fire load spaces in the construction of weight-sensitive high speed passenger vessels. The new ferries operate in the Puget Sound providing passenger-only service from Vashon Island to downtown Seattle. The sister vessel, MV Doc Maynard operates from West Seattle to downtown. “We are honored to have this opportunity to construct world-class passenger ferries that are fuel efficient, dependable, and cost-effective,” stated All American Marine CEO, Matt Mullett. King County’s two new vessels will be supported AAM partnered with the naval architecture firm, Teknicraft Design Ltd., of Auckland, New Zealand for the hull design. Each 105’ x 33’ aluminum catamaran features an advanced hull shape that was custom designed using digital modeling and Computational Fluid Dynamics (CFD) analysis testing. The hull design is complemented by Teknicraft’s signature integration of a wave piercer that is positioned between the catamaran sponsons to break up wave action and ensure reduced drag while enhancing passenger comfort.
