History

In the 1980s the RNLI's and all-weather lifeboats provided coverage 30 miles (48.3 km) out to sea, operating at up to 18 knots (35.3 km/h) to cover the distance in two hours in good weather. However the RNLI felt that they needed the capability to extend their coverage to 50 miles (80.5 km) radius which would require lifeboats with a top speed of 25 knots (49 km/h). This resulted in the 14 metres (45.9 ft) Trent and 17 metres (55.8 ft) lifeboats.

The prototype for the Trent class was built in 1991. It was used for trials until 1994, when it was put into active service at Alderney Lifeboat Station. It remained on station there until their own boat was available in 1995, since when it has served in the relief fleet. Construction of its sister boats continued until 2004.

Design

The Trent is intended to lie afloat at moorings. It has five water-tight bulkheads to create six compartments: fore peak; fore store; survivor cabin; tank space; machinery space; and aft peak steering compartment. Above these is the main deckhouse which has seats for the six crew and a doctor. This is another water-tight space which provides the boat's self-righting capability.

Designed and built by Green Marine, each boat is constructed of over 100 mm thick fibre reinforced composite topsides, single laminate double hull bottoms, 4 water-tight bulkheads and prepreg epoxy, glass and Kevlar
Kevlar
Kevlar is the registered trademark for a para-aramid synthetic fiber, related to other aramids such as Nomex and Technora. Developed at DuPont in 1965, this high strength material was first commercially used in the early 1970s as a replacement for steel in racing tires...

 shields.

The Trent has a service life of 25 years, although current estimates appear to exceed these original operational confines due to constant on-station maintenance, periodic refitting and sporadic repairs. In comparison with its predecessors, the boat has numerous additional advantages which aid in the overall success of every launch. One detail would be its condensed hull, which allows it to operate in significantly constrained locations (such as marina berths and dense quayside scenes).

Another aspect aiding in its confined manoeuvrability would be the bilge keels which aid in protecting its twin drive props. Its hull sheerline sweeps down into an area known as the welldeck, which dramatically helps with ease of casualty recovery. The remote location of an a-frame hoist also provides additional assistance for particularly awkward recoveries (such as casualties in stretchers) .

As of 2006, each Trent class lifeboat is complemented with an array of advanced technologies. Each device provides full assistance in search and rescue
