Swiftships, Inc. of Morgan City, La., recently delivered the crew/supply boat C/Raider to CO-MAR Offshore Corporation, also of Morgan City. The vessel is the first in the CO-MAR fleet to be fitted with a ZF 2 1/2:1 reduction gear. Her MTU engines combined with the ZF gears allow the craft to use larger propellers. This results in the vessel being able to transport heavier loads at higher speeds.
A twin-screw vessel, the C/Raider has a propulsion package consisting of two MTU 12V331 engines and ZF gears. A Delco 30-kw generator is driven by two Detroit Diesel 3-71 engines. On sea trials the boat attained speeds up to 25 knots.
Having passed U.S. Coast Guard inspection, the C/Raider is certified to carry 65 passengers, aviation fuel, and corrosives. Accommodations are provided for a five-man crew.
With a cargo deck space 58 feet by 16 feet, the vessel's cargo capacity on deck is 110 long tons; below-deck capacity is 52 tons. Loaded draft is 6 feet. The tanks hold 3,740 gallons of fresh water, 13,350 gallons of drill water, 500 gallons of drinking water, and 4,000 gallons of fuel, giving the vessel an endurance of 40 hours.
Columbian supplied the propellers, four-blade, 42-inch by 38-inch Crewboat Bronze models. Electronics were supplied and installed by Bibbins & Rice. They include a Furuno radar, two radiotelephones, a Drake TRM-1 SSB radio, Drake MRF-55 VHF radio, Texas Instruments TI-9900 automatic Loran, an Impulse 600CV depth sounder, and Danforth C654C compass.
C/Raider is equipped with lifesaving gear, and has full firefighting capabilities, and air-conditioning and heating throughout.
