What length are the 'Cape-class' motor lifeboat vessels that are used in the Coast Guards of Canada and the US?

The Canadian Coast Guard maintains a fleet of 14.6 m (47 ft 11 in) Cape-class motor lifeboats, 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.

In spite of its name, the CCGS (Canadian Coast Guard Ship) 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.

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). Constructed from marine-grade aluminium, ships have draught lengths of 4 feet 6 inches (1.37 m). They contain 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.

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 litres; 330 imp gallons) and ranges of 200 nautical miles (370 km; 230 mi) when cruising. 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).
