Southwest Marine Completes Successful Conversion Of 5 Zapata Gulf Marine Tugs One of the five tugs that were drydocked at Southwest Marine to be brought up to U.S. Navy specifications. Southwest Marine, Inc. recently finished ex- tensive modifications on five tugs for the newly formed Zapata Gulf Marine. The tugs are part of a fleet of 325 vessels formed by the January 1985 merger of Zapata Marine, Jackson Marine and Gulf Fleet. The resulting Corporation of Zapata Gulf Marine has become one of the largest oper- ators of oilfield services and supply vessels. The tugs will be used for the new U.S. Navy Ship Assist contract awarded to Zapata Gulf Marine. The five tugs, Mister Randy, Mister Mike, Mister Don, Mister Marshal D. and Cheryl Anne, came from as far away as Singa- pore to their new port of San Diego, where they were drydocked at Southwest Marine to be brought up to U.S. Navy specifications. The work accomplished included installation of rubber fendering, special firefighting and communications equipment, insulation of pro- peller guards, underwater hull preservation, and ABS certification. Uniden® Offers Three New Electronic Aids —Literature Available Uniden Company, Indianapolis, Ind., now has three new electronic aids available. The MC35 marine power hailer, the MC400 chart recorder and the MC300 digital depth indicator. The Uniden MC35 marine power hailer is a powerful, 40-watt hailer with a four-station intercom, automatic foghorn with settings for international, inland and Great Lakes opera- tion, a momentary or lock-on siren, a volume control for both foghorn and siren and a hand- held microphone.

The MC35 is protected by a corrosion-resis- tant, high-impact plastic case and has been designed for easy use and durability. Projector horns and remote speakers that are compatible are also offered. For literature containing further information on the Uniden MC35 power hailer, Circle 65 on Reader Service Card The Uniden MC400 chart recorder features convenient front panel keypad controls, an LCD display of surface temperature and water depth at a glance. It ignores annoying echoes that can make chart recordings difficult to interpret. It "knows" that only bubbles and debris rise straight up while fish rise gradually at angles. The 4-inch chart recorder has six range scales from 0-10 feet up to 0-320 feet making it ideal for shallow water, bay and coastal shelf fishing. It also features an event marker, chart light, 200 KHz transducer, all cabling and a spare paper cassette. It is housed in a weather resistant plas- tic case, has adjustable mounting brackets, non- corrosive plastic latches, watertight seal gaskets and detachable power and transducer plugs for easy removal and storage. George Rabatin, national sales manager of marine products, says the MC400 "permits the fisherman to lay the bait virtually right in the fishes mouth." For further information on the MC400 chart recorder from Uniden, Circle 71 on Reader Service Card The Uniden MC300 digital depth indicator is ideal for shallow water navigation and charting. It features a continuous digital readout of water depths from zero to 300 feet and a front panel switch that allows for an audible shallow water alarm at either 5 or 10-foot water depths. The MC300 is compact, 3-% inches wide by 7-% inches long by 2-% inches high and will mount almost anywhere. It comes equipped with a 200 KHz transom-mount transducer.

Hope & Narragansett Bays DOCKING & COASTAL TOWING All Diesel Fleet PROVIDENCE STEAMBOAT COMPANY 1 India St., Providence, Rl 02903 401-331-1930 The recent launching of the 37-foot tug Max Effort near Virginia Beach represented the cul- mination of 61/2 years of effort on the part of the boat's creator, Ray Emanuelson, who de- signed the vessel based on a variety of tugs he saw around the boatyards of Norfolk as a young- ster, and constructed it in his garage. The hull of the Max Effort consists of three layers of 1V2 - by 3A -inch yellow pine overlaid with four layers of 10-ounce fiberglass. The keel area has an additional four layers of fiberglass. A pair of Lugger diesels manufactured by Alaska Diesel Electric of Seattle were chosen for the tug, each delivering 80 hp at 2,500 rpm. The four-cycle, direct injection units are based on American-made John Deere blocks. The Lugger diesels have a simple design with many long-life features. All service points are located on one side for easy maintenance. The cast-iron, fresh- water cooling system has an extra large expan- sion tank and liquid cooled exhaust manifolds. Wet cylinder liners provide excellent heat dissi- pation. They are individually replaceable for easier maintenance and less expensive over- haul. The Max Effort weighs 14 tons and cruises at approximately 8.5 knots at 1,600 rpm. Maxi- mum speed is above 12 knots at 2,475 rpm.
