Introduced in the early 1930's, the single screw Liverpool class lifeboat was one of the first proper carriage launched motor lifeboats. They weren't self righting but were extremely stable, even at a 90 degree list. They were based upon the Liverpool class pulling and sailing type lifeboat, which had excellent sea handling qualities. Light enough to be launched over a carriage, which had to be pulled across sand, they were still powerful enough to be relatively fast for the time. They were very popular at stations where they served and many had distinguished service records. 'Foresters Centenary', which served at Sheringham, was known as the 'Airman's Lifeboat' during World War Two as she reputedly rescued more downed airman than any other lifeboat.

 

 The Liverpool class lifeboat was designed to be carriage launched, and so had to be light. They weighed only eight tons, light for a motor lifeboat and bear in mind that one ton of this was the keel which made it extremely stable in the water. They could carry up to thirty passengers with ease in heavy seas in safety, and although they were non-self righting they were stable even at a 90 degree list, which would capsize most boats.
