Robert Allan has completed the design of a new generation of high endurance self-righting search and rescue lifeboats for the Canadian Coast Guard.
The design was developed from the successful similar vessels known as the "Severn" Class operated by the Royal National Lifeboat Institution (RNLI) of the United Kingdom. The new Canadian design is larger, with a greater range than the RNLI vessel and has been specifically designed to handle the worst weather encountered year around in the waters off Newfoundland and Nova Scotia.
The new design is also for construction in aluminium rather than FRP – as are the Severn Class.
Construction of 10 vessels of this cass is being considered by the Coast Guard to replace existing Arun Class vessels, which are reaching the end of their service life.
The high endurance search and rescue lifeboats will provide greatly enhanced speed, range and weather operability to the Coast Guard enhancing their capability to perform Search and Rescue Missions.
Measuring 19 metres x 6.3 metres, the new search and rescue lifeboats are self-righting and capable of safe operation in extreme weather up to Beaufort Force 12 conditions and are able to withstand 12 metre seas. Powered by engines rated to 2,400kW, the vessel's operational speed is approximately 23.5 knots.
