The station also operates a D-class (IB1) inshore lifeboat, RNLB Flt Lt John Buckley RAF (D-827).

[4] In 1925 work began on the construction of a new boathouse built on a piled platform with a gangway from the shore, which had a trolley track.

Watson-class lifeboat RNLB Canadian Pacific (ON 803) launched approximately 50 times, often to rescue pilots from fallen aeroplanes.

[6][7] On 11 July 1940, the lifeboat rescued John Peel, the commanding officer of RAF 145 Squadron, minutes after he abandoned his damaged Hurricane (P3400) off Selsey Bill.

The deep water roller slipway was re-configured to have a gradient of 1:5, and the station was given a newly fabricated steel approach gangway from the shore.
