The Canadian Coast Guard maintains a fleet of 14.6 m (47 ft 11 in) Cape-class motor lifeboats[2] , based on a motor lifeboat design used by the United States Coast Guard. In September 2009 the CCG announced plans to add five new lifeboats, bringing the total number of Cape-class lifeboats to 36.

The vessels are staffed by a crew of four, two of whom are rescue specialists.[3][4][5] In spite of its name, the CCGS Cape Roger is a larger patrol vessel, not a Cape-class lifeboat. The CCG also maintains some larger motor lifeboats based on Arun-class lifeboats designed in the United Kingdom.

Design[edit]

Cape-class motor lifeboats have displacements of 20 short tons (18 t) and total lengths of 47 feet 11 inches (14.61 m) and beam lengths of 14 feet (4.3 m).[6] Constructed from marine-grade aluminium, ships have draught lengths of 4 feet 6 inches (1.37 m). They contains two Caterpillar 3196 diesel engines providing a combined 900 shaft horsepower. They have two 28 by 36 inches (710 mm × 910 mm) four-blade propellers, and each ship's complement is four crew members and five passengers.[6]

The lifeboats have maximum speeds of 25 knots (46 km/h; 29 mph) and cruising speeds of 22 knots (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.[6] They are capable of operating at wind speeds of 50 knots (93 km/h; 58 mph) and wave heights of 30 feet (9.1 m). They can tow ships with displacements of up to 150 tonnes (170 short tons) and can withstand 60 knots (110 km/h; 69 mph) winds and 20 feet (6.1 m)-high breaking waves.[6]

Communication options include Raytheon 152 HF-SSB and Motorola Spectra 9000 VHF50W radios, and a Raytheon RAY 430 loudhailer system.[6] The lifeboats also support the Simrad TD-L1550 VHF-FM radio direction finder. Raytheon provides a number of other electronic systems for the lifeboats, 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.[6]
