John Manly Shipyard Delivers MTU-Powered Patrol Vessel

RivTow Straits Limited recent- delivered the Canadian Fisher- ies patrol vessel James Sinclair (shown above), built at the com- pany's John Manly Shipyard in Vancouver, B.C. Built at a cost of about $7 million, the new vessel is of all-welded aluminum construction, and features such advanced technology as a Com Dev satellite navigator, Sperry controls (for radar, steering, and gyrocompass), Muirhead weatherfax recorder and printout system, and computerized Decca Isis system for internal mechanical control.

Other electronics include Furuno FD 171 radio direction finder, Com Dev Internav Loran C navigator and investigator, two Sperry radars, Sperry doppler speed log, Wesmar sonar, Simrad depth sounder, two Motorola SSB radios, and two Marconi VHF radios.

Two MTU 12V538TB91 diesel engines, each rated 2,300 bhp at 1,790 rpm, provide main propulsion power. They drive Lips controllable- pitch propellers through Lohman & Stolterfoht reduction gears. Electric power is supplied by three Caterpillar 3406 diesels driving Siemens 460-volt gener- ators. The main engines are fitted with Maxim silencers.

The James Sinclair has an overall length of 124 feet, molded beam of 27 feet 6 inches, and molded depth of 12 feet. She carries 23,000 imperial gallons of fuel and 1,000 gallons of potable water. The vessel attained a trial speed of 16y2 knots, but normal cruising speed is 12 knots.

Deck gear includes a Harrison & Robbins anchor windlass and capstan, Sperry steering gear, Washington Anchor anchors, Atlas crane, Beaufort Canada liferafts, Zodiac lifeboats and boarding boats, and John Manly closures.

Deck covering was supplied by Raeco Western, and paint by International Marine Coatings.

The new vessel, named after former Federal Fisheries minister James Sinclair and christened by his wife, Kathleen, will patrol Canada's 200-mile territorial limit and will enforce Federal Fish- eries regulations. She will be the largest fisheries patrol vessel on Canada's West Coast, and replaces The Howay.

RivTow spokesman David Leith said that the Sinclair is the largest aluminum vessel built by the company. "This is quite unusual for a vessel of this size," said Mr. Leith, commenting on the aluminum construction. "They usually are made of steel but in this case they were looking for speed."
