42 MN February 2011 Kvichak Launches M/V Defender V Kvichak Marine Industries, Inc. recently launched and completed sea trials for M/V Defender V, a new design all-aluminum foil assist- ed catamaran. Designed by Kvichak Marine, this 57.8-ft vessel can be used as a fast response patrol boat, survey boat, crew boat or general work boat. The Defender V is pow- ered by twin Scania DI12 69M marine diesel engines rated for 691 bhp at 2,300 rpm. The engines are coupled to ZF 360A transmissions that drive Michigan propellers. In trials, the Defender V achieved a flank speed of 30+ knots. The vessel features a very large aft work-deck with tie-pockets, a 2,200 lb SWL A- frame with hydraulic drum winch and a side mounted davit with 500 lb SWL winch. The A-frame can facilitate launch and recovery of skiffs/ROVs and can accommodate an over-height 20-ft long by eight-ft wide container loaded on the aft deck.

Bisso & Son Inc. fleet in December. The tugboats, which measure 96 ft in length and 34 ft in beam, are the fifth and sixth hulls of this class of tug to enter service with Bisso. These Rolls- Royce US205MK2 Z-drive tugs are powered by twin Caterpillar 3516-C Series II main engines that produce a total of 4,000 bhp, driving Schottel ASD propulsion units, and are fitted with a Markey hawser winch forward and a Markey capstan aft. These work boats are the latest in a line of tugs that Jensen has designed for Eastern Shipyard, which built the tugs in Panama City, Fla. Since 2001, 17 tugs of this class have entered service with a variety of operators and can be seen on the water from Galveston, Texas, to Portland, Maine. Installed power for this class of tugs has ranged from 4,000 to 6,000 bhp, with bol- lard pulls in excess of 75 short tons.
