History

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. There was also a beach type with 7 inches more beam and strengthened hulls to withstand the rigours of beach launching. Production ran from 1931 to 1939 and thirteen boats were completed. Between 1948 and 1952 a further five boats were built before attention turned to the much modified 42ft Watson type which appeared in 1954.

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 Beach types, as well as being wider, had various differences in deck layout, the first three (ON 751, 761/2) having end boxes and the fourth (ON 783) having raised bulwarks. 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. From 1963 eleven of the boats were re-engined with 47 bhp Ford-based Parsons Porbeagle 4-cylinder diesel engines.
