Key Features – The Finer Details
The Tamar class lifeboat is a relatively new addition to the RNLI’s fleet – designed to gradually replace the Tyne class. The Tamar class lifeboat is designed primarily to operate from a slipway, but can also lie afloat and, like all RNLI all-weather lifeboats, is inherently self-righting. Her mast and aerials can be lowered to fit into a boathouse. The Tamar is fitted with an integrated electronics Systems and Information Management System (SIMS) designed to offer her crew the ability to monitor, operate and control many of the boat’s systems directly from the safety of their shock-mitigating seats. These bespoke seats enhance crew comfort and safety. They also incorporate essential controls such as throttles and a joystick with the trackball for the SIMS screen close to hand. SIMS provides access to all communications (VHF, MF, DF and intercom), navigation (radar, chart, DGPS, depth and speed) and machinery monitoring including engines, transmission, fuel and bilge.

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 daughter boat housed under the aft deck and 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. Other equipment includes a portable salvage pump carried in a watertight container.

In return for their dedication and commitment, the RNLI makes a pledge to its volunteer crew that its rescue equipment is maintained to the highest standards and able to respond to emergencies at sea
