CCGS Cape Hearne is one of the Canadian Coast Guard's 36 Cape-class motor lifeboats.[1] She as christened in 2005, at the Canadian Coast Guard station at Kingston, Ontario.

On March 27, 2012, Cape Hearne and Canadian and American helicopters and aircraft were deployed to help rescue the crew of the tugboat Patrice McAllister, which was disabled due to a fire in her engine room.[2]

Cape Hearne is near the mouth of the Coppermine River, on the Arctic Ocean, and is named after Samuel Hearne the first European to map the Coppermine River.[1]

Design

[edit]

Like all Cape-class motor lifeboats, Cape Hearne 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).[3] Constructed from marine-grade aluminium, it has a draught of 4 feet 6 inches (1.37 m). It contains two computer-operated Detroit DDEC-III 6V-92TA diesel engines providing a combined 870 shaft horsepower (650 kW). It has two 28-by-36-inch (710 mm × 910 mm) four-blade propellers, and its complement is four crew members and five passengers.[3]

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.[3] Cape Hearne 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.[3]

Communication options include Raytheon 152 HF-SSB and Motorola Spectra 9000 VHF50W radios, and a Raytheon RAY 430 loudhailer system.[3] 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.[3]
