Excursion/fishing vessel Nautilus II built by Westport Shipyard is powered by twin Detroit Diesel 12V92N engines with total output of 1,020 bhp for top speed of 21 knots. Westport Yard Delivers Multipurpose Fiberglass Excursion/Fishing Vessel The fiberglass excursion and charter fishing vessel Nautilus II was completed recently by Westport Shipbuilding, Inc. of Westport, Wash., and delivered to Meatball Bait Company of San Francisco. De- signed by naval architect Jack Sarin of Bainbridge Island, the 75- foot boat will be used by owner Jim Williams for both day excursions and charter fishing, as well as whale-watching trips. She is certi- fied by the U.S. Coast Guard to car- ry 75 passengers, but has sleeping bunks for 34 people plus the operat- ing crew to be used on overnight trips. Extensive owner-furnished galley equipment was installed, and a broad range of electronics gear equips the vessel for offshore opera- tions. The hull is built of Airex foam cored fiberglass; the resin used is of fire-resistant composition, in keep- ing with the boat's mission as a pas- senger vessel. Westport also molded the fiberglass house shell for above- deck accommodations. The Nautilus II is propelled by two 510-bhp Detroit Diesel 12V92N engines, driving Coolidge three- bladed bronze propellers via Twin Disc 514 2.5:1 reduction and Aqua- met shafts. The 3-inch shafting was machined by Alaskan Copper & Brass of Seattle. This propulsion plant gives the boat a cruising speed of 18 knots at 1,700 engine rpm, and a top speed of 21 knots. Morse Twin S propulsion controls were supplied by Englund Marine of Westport. The engine spaces are protected by a Halon fire-suppress- ing system from Automatic Sprin- kler of Pasadena, Calif. Other safety equipment includes a Marlow fire pump from Cascade Machinery, Seattle; fire hoses and rack from Safety & Supply, Seattle, and life- saving gear from Cal-June of North Hollywood, Calif. The vessel's electronics gear, sup- plied by Baytronics of Oakland, Cal- if., features a number of Raytheon units, including a Model 1010 64- mile radar, JFV-516 video sounder, JFV-760 sounder recorder, Rayfax 500 facsimile, Raynav 750 MKII Lo- ran C, Ray-150 SSB radio, Ray-400 loudhailer, and NWU-52R video plotter. Other electronics equip- ment includes a King 7200 VHF, Regency Polaris ADF-VHF, Combi CS-3001 stereo, Dytek 200 C/F sea- temp indicator, Bearcat 210XK ra- dio channel scanner, RDI Bridge Master watch alert, RCA sidetrack television, and Mitsubishi VCT. Two 20-kw Northern Lights gen- erators from Alaska Diesel Electric of Seattle supply electrical power. Deck gear includes a Smith Broth- ers winch from Englund Marine, and dock lines and fenders from Fisheries Supply of Seattle. The anodized aluminum windows with tinted glass were supplied by Penin- sula Glass of Vancouver, Wash.
