CCGS Cape Cockburn is one of the Canadian Coast Guard's 36 Cape-class motor lifeboats.[1] Cape Cockburn was built in the Victoria Shipyards, in Vancouver, and is stationed at Powell River, British Columbia.

Design

Like all Cape-class motor lifeboats, Cape Cockburn has a displacement of 20 short tons (18 t), a total length of 47 feet 11 inches (14.61 m) and a beam of 14 feet (4.3 m).[2] Constructed from marine-grade aluminium, it has a draught of 4 feet 6 inches (1.37 m). It contains two, computer-operated Caterpillar 3196 diesel engines, providing a combined 900 shaft horsepower (670 kW). It has two 28 by 36 inches (710 mm × 910 mm) four-blade propellers, and its complement is four crew members and five passengers.[2]

The lifeboat has a maximum speed of 25 knots (46 km/h; 29 mph) and a cruising speed of 22 knots (41 km/h; 25 mph). Cape-class lifeboats have fuel capacities of 400 US gallons (1,500 L; 330 imp gal) and ranges of 200 nautical miles (370 km; 230 mi) when cruising.[2] Cape Cockburn is capable of operating at wind speeds of 50 knots (93 km/h; 58 mph) and wave heights of 30 feet (9.1 m). It can tow ships with displacements of up to 150 tonnes (170 short tons) and can withstand 60-knot (110 km/h; 69 mph) winds and 20-foot (6.1 m)-high breaking waves.[2]

Communication options include Raytheon 152 HF-SSB and Motorola Spectra 9000 VHF50W radios, and a Raytheon RAY 430 loudhailer system.[2] The boat also supports the Simrad TD-L1550 VHF-FM radio direction finder. Raytheon provides a number of other electronic systems for the lifeboat, including the RAYCHART 620, the ST 30 heading indicator and ST 50 depth indicator, the NAV 398 global positioning system, a RAYPILOT 650 autopilot system, and either the R41X AN or SPS-69 radar systems.[2]
