Irene Muriel Rees was funded principally from the legacy of Miss Irene Muriel Rees of Ashtead, Surrey who died in August 2008. For many years Miss Rees had a summer holiday home at the Naze. She also made a significant donation to the restoration of the old Walton lifeboat James Stevens No. 14. Smaller legacies from Mrs Anne Cormack-Evans of Melton Mowbray and Mrs Annie Clara Mabel Arnold of Cambridge were also used to fund the total cost of approximately £2.7million.
The Tamar is fitted with an integrated electronic Systems and Information Management System (SIMS) so that the crew can monitor, operate and control many of the boat’s systems directly from their shock-mitigating seats, improving their safety.
The bespoke seats enhance crew comfort and safety. They also incorporate essential controls such as throttles and joystick with the trackball for the SIMS screen close to hand. The Tamar’s propellers and rudders lie in partial tunnels set into the hull that, along with steel-lined main and bilge keels, provide excellent protection from damage in shallow water or slipway operations. In addition to her twin engines, the lifeboat is fitted with a hydraulic-powered bow thruster for improved manoeuvrability. The Tamar carries a Y boat, an inflatable powered daughter boat housed under the aft deck, which can be deployed from a hinged door in the transom.
The Y boat has a 15hp outboard engine and is used in moderate conditions to access areas the lifeboat cannot reach. Comprehensive first aid equipment includes stretchers, oxygen and Entonox and other equipment includes a portable salvage pump carried in a watertight container.
