# Mersey-class lifeboat

Mersey-class lifeboats are All-weather lifeboats operated by the Royal National Lifeboat Institution (RNLI) from stations around the coasts of Great Britain and Ireland, with three former RNLI boats operated by ADES Uruguay, and one by Bote Salvavidas de Valparaiso, Chile . They are capable of operating at up to 17 knots (31 km/h) and can be launched from a carriage or by slipway.
The class name comes from the River Mersey which flows into the Irish Sea in north west England.

## History

During the 1960s and 1970s the RNLI introduced fast lifeboats capable of considerable greater speeds than the 8 knots (15 km/h) of existing designs. The first of these were only able to be kept afloat as their propellers would be damaged if launched using a slipway or carriage. In 1982 the steel-hulled Tyne-class came into service which could be launched down a slipway but weighed 25 tons so was not suitable for being moved across a beach on a carriage. The answer was to build a smaller boat with an aluminium hull, which became the Mersey Class.
The first, unnamed, Mersey was built in 1986 and undertook trials during 1987 and 1988. It was then taken out of service and sold the following year. It was working as a trip boat in Westport, County Mayo in 2008 carrying the name Spirit. Two more boats were built in 1988, with the first one to take up active service going to Bridlington Lifeboat Station the following year.
In 1989, 12-11 Lifetime Care (ON 1148) was built with a fibre-reinforced composite (FRC) hull. Boats built in 1990 continued to use aluminium but from 1991 FRC became the standard hull material.
In 2014, the first of the Shannon-class lifeboats replaced the Mersey lifeboats at Dungeness, Exmouth and Hoylake. The RNLI intended to have 25 knot lifeboats at all offshore lifeboat stations by the end of 2019. However, this target has not been met, with two Mersey-class lifeboats still on station at Douglas and Newcastle (Mar 2025).
On Wednesday 13 December 2023, Her Royal Highness The Duchess of Edinburgh joined RNLI representatives at Windsor Castle for the handover of RNLB 12-30 Her Majesty The Queen (ON 1189) to the Chatham Historic Dockyard.

## Description

The Mersey is designed to be launched from a carriage, but can also lie afloat or be slipway launched when required. Its propellers are fully protected from damage when launching or in shallow water, by partial tunnels and two bilge keels. Its low height can be further reduced by collapsing its mast and aerials which then allows it to be stored in a boathouse. A sealed cabin gives it a self-righting ability.
Power comes from two 3208T Caterpillar turbo-charged marine diesel engines giving 285 hp at 2,800 rpm. It carries 1,110 litres (290 US gal) of fuel to give it a range of 240 nautical miles (440 km). It has a crew of six and can carry an inflatable X Boat which it can deploy at sea. Its survivor compartment can carry 43 people, but more than 21 prevents self-righting should the boat capsize.
