The Severn class lifeboat was introduced in 1995 and is the largest in the RNLI fleet. It carries a Y class inflatable boat that can be launched from the lifeboat with a crane. The Severn has the same hull shape as the Trent class.

Speed

Construction
Hull: Fibre reinforced composite with single-skin section below the chine and 100mm thick foam-cored sandwich above. Deck and superstructure: 25mm foam-cored sandwich.
The Trent class was introduced in 1994. It has the same hull shape as the Severn class but is a smaller version. The sheerline sweeps down the side of the vessel for easier recovery of survivors.
The Mersey class lifeboat was introduced in 1988 and was the first of the "fast" carriage lifeboats. Although designed to be launched from a carriage this type of lifeboat can be launched from a slipway or can be moored afloat. It has a box-shaped wheelhouse that is set well to the rear of the vessel. The propellors are protected by partial tunnels and substantial bilge keels. The last Mersey was built in 1993.

HRH The Princess Royal, (Civil Service No 41) (12-009) at St Ives The Four Boys (12-19) was at Sennen Cove from 1991 to 1998.
The Tyne class lifeboat was the first "fast" slipway lifeboat. It is the main slipway launched lifeboat class but it can also lie afloat. Features include a low-profile wheelhouse and a separate cabin behind the upper steering position. The propellers are protected by substantial bilge keels. The last Tyne was built in 1990 and the class is gradually being replaced by the Tamar class.

The Tamar class lifeboat was the RNLI's latest design in service, until the Shannon was introduced in 2013, and was destined to replace the ageing Tyne class, which is coming towards the end of its useful life. The Tamar is larger and faster than the Tyne and can be launched from a slipway or lie afloat. It includes a computerised Systems and Information Management System (SIMS) that enables crew to control many of the lifeboat's functions remotely from the safety of their seats. Other features include advanced ergonomics, that reduce the impact on the crew as the lifeboat crashes through waves, and a powered Y boat stored, fully inflated, behind a transom door to allow immediate deployment. The first Tamar went on station at Tenby in Wales in 2006. 27 Tamar class lifeboats were built between 2006 and 2013.
The first Shannon class lifeboat, Jock and Annie Slater, was accepted into the RNLI Relief fleet on 11th July 2013. The Shannon will gradually replace the Mersey class lifeboat, which first came into service in 1989 and is now nearing the end of its planned 25-year life span.
This is the first RNLI sea-going lifeboat to be powered by Hamilton waterjets instead of propellers, making it more manoeuvrable and safer to operate in shallow waters, as well as reducing the risk of damage during launch and recovery.

The D class has been the workhorse of the service since the 1970's. It is small and highly manoeuvrable, making it ideal for rescues close to shore in fair to moderate conditions. It has a single outboard engine and can be righted manually by the crew following a capsize. The design of the D class has continued to evolve since its introduction. The details below are for the latest version that was introduced in 2003.

It is a fast response craft, developed for use with waterjets, and is used at two stations on the River Thames (Chiswick and Tower Pier). The E class can operate in both daylight and darkness and has an assisted righting capacity similar to the B class. The Mark II was introduced in 2011.

Hovercraft were introduced into the fleet in 2002. They are able to operate in mud, sand and very shallow water and are particularly useful for shoreline searches. Lift is provided by a build up of air pressure under the craft and thrust by two large fans mounted on the back that act in the same way as aeroplane propellers. Steering is provided by aerofoil-shaped rudders located behind the propellers.

The X-Class Lifeboat is used as a small tender carried on board the RNLI All Weather lifeboats. They are normally found carried onboard Tyne and Mersey class lifeboats. They are also carried onboard the new Shannon class.
Primarily used for assisting in cliff incidents where the casualty is near the water but the All Weather Lifeboat can not get into the base of the cliffs due to rocks. Also used for operating in shallow water near beaches and in estuaries.
Usually carried on board the "mother" lifeboat. Carried on Trent class lifeboats for use in cliff incidents where the casualty is near the water and rocks prevent the Trent from getting near the base of the cliff. A few XPs, with greater propulsion, work alongside inshore lifeboats on river estuaries and on The Broads.

Stored fully inflated in a compartment behind the transom of the "mother" lifeboat. Mother boats are now Severn and Tamar class lifeboats. (Y boats were used on the Arun class lifeboats before these were retired.)
A variety of vessels are used as boarding boats to get from the shore to the lifeboats that are moored afloat away from any pontoon or harbour wall.
At St Mary's on the Isles of Scilly the boarding boat is launched down the lifeboat station slipway to get the crew to the Arun class lifeboat stationed on a harbour mooring. This is the only place in the UK where this happens. (See image above)
Specifications
A variety of boats are used as boarding boats, including inflatables, but no standard RNLI boarding boat.
Launch
Various methods of launching: Slipway (St Marys IOS only), davit, crane or moored alongside the harbour.
