All American Marine, Inc. (AAM) has completed construction and delivered the third of three low-wake and high-speed passenger vessels for Kitsap Transit. The Reliance and Lady Swift are aluminum catamarans with composite superstructures, and were delivered to Kitsap Transit in Bremerton in March and Julyh of 2019 respectively. The vessels were designed by Teknicraft in Auckland, New Zealand and will operate on Kitsap’s current cross-sound ferry route between Bremerton and downtown Seattle. The design of these vessels was based upon the successful ultra-low-wake Rich Passage 1 (RP1), built by All American Marine in 2011. AAM, the exclusive builder of Teknicraft Design hulls in North America, was tapped as the sole source to build this vessel. In 2005, through a series of federally funded wake wash studies, it became evident that the wake signature of a Teknicraft standard hydrofoil-assisted catamaran produced the least amount of wake wash energy within its vessel class. Kitsap Transit contracted with Pacific International Engineering of Edmonds, WA to spearhead the ongoing research efforts in conjunction with All American Marine and Teknicraft to further enhance and optimize the vessel’s design. Teknicraft’s principal naval architect, Nic de Waal, worked with hydrodynamicists from the University of Iowa’s IIHR-Hydroscience and Engineering Research Center as well as naval architects from INSEAN in Rome, Italy to model an ultra-low wake hull. Coastal specialists from Golder Associates of Redmond, WA evaluated the proposed vessel’s performance in terms of wake generation and resistance.
