Mersey
The Mersey class lifeboat was introduced in 1988 and was the RNLI's first ‘fast’ carriage lifeboat. It was designed to be launched from a carriage but can also lie afloat or be launched from a slipway. Propellers are protected by partial tunnels and substantial bilge keels. The last Mersey was built in 1993.
