First U.S. Commercial SWATH To ABS Class Under Construction —Color Brochure Offered Maritime Reporter Staff Model of the possible final configuration of the Navatek I. The first U.S. commercial SWATH (Small- Waterplane Area Twin-Hull) vessel, the 500- passenger ferry Navatek I prototype, to Ameri- can Bureau of Shipping Class is being built by Pacific Marine, Honolulu, Hawaii, at Thompson Metal Fab shipyard in Vancouver, Wash. According to Michael Schmicker, vice president-business development, Pacific Ma- rine, the 140-foot vessel was scheduled to be launched last month. Sea trials with a tempora- ry "mini-superstructure" and wheelhouse were scheduled for late this month. According to Ken Plyler, construction man- ager, Pacific Marine, the temporary superstruc- ture, which was prefabricated by Northwest Marine Iron Works, Portland, Ore., in conjunc- tion with Thompson Metal Fab, consists of the anchor bow, bulwarks, wet deck with resilient mounts, and bulkheads with staterooms. A pre- fabricated pilothouse from Singapore will be placed atop the temporary superstructure. After trials, Pacific Marine plans to operate the vessel on a number of cruises and demon- stration rides on the West Coast before sailing her to Hawaii. Final determination of her super- structure will be based on her ultimate use. The Navatek I prototype is 140 feet long, has a beam of 53 feet, displacement of about 365 tons, and variable draft ranging from 8 to 12 feet. She will be powered by two Deutz MWM 16V-816CR diesel engines with a continuous rat- ing of 1,350 hp each. She will be fitted with Ulstein reduction gears driving Ulstein controll- able-pitch, four-bladed propellers. Auxiliary power will be provided by two GM 6-71-powered generators rated at 99 kw each. The vessel is classed by ABS, +A1 Ferry Hawaiian Interisland Service, +AMS. The structural design of the vessel consists of two demi-hulls, connected by a cross-structure con- sisting of two box beams. There are two vertical struts per side which connect the lower hulls to the upper structure. The lower hulls have hemi- spherical endcaps at the bow. Aft of this are two cylindrical lengths of hull of circular cross sec- tion. The deckhouse is mounted on flexible mounts. At present, Singapore Slipway & Engineering Co., Singapore, has a non-exclusive license to market the patented Navatek designs in Asia. Pacific Marine is negotiating with an Australian company interested in obtaining a technology license for the design.
