The 41 ft Watson-class was a non-self-righting displacement hull lifeboat built between 1933 and 1951 and operated by the Royal National Lifeboat Institution between 1933 and 1982.
The 41 ft Watson was designed for service at stations which required a larger and more powerful boat than the standard carriage launched types, but which could not accommodate the larger Watson types through boathouse or slipway constraints.
The boat is not to be confused with the earlier 41ft Beach Type Motor lifeboat, which was developed from the Norfolk and Suffolk-class lifeboats. Production ran from 1933 to 1939, with thirteen lifeboats completed.[1]
Between 1948 and 1952 a further four boats were built, before the introduction of the much modified 42ft Watson-class lifeboat, which appeared in 1954.[2]
Description
The 41 ft Watson had an aft cockpit, with a cabin ahead of it containing the engine controls. There was a separate forward shelter and there was room in the two for sixteen people. The boats carried two sails as an auxiliary to the twin Weyburn AE6 6-cylinder petrol engines.

The type was put back into production in 1948, nine years after the last had been built, in a revised version with an enlarged cabin which replaced the forward shelter.[2]
From 1963, eight of the boats were re-engined with 47 bhp Ford-based Parsons Porbeagle 4-cylinder diesel engines.[2]
