Further improvements to the station were undertaken at the station in 1939. Work was carried out on the boathouse to enlarge its capacity to accommodate a new Watson-class Twin screw motor lifeboat. The new lifeboat was the  which arrived on station and was christened and was dedicated by the Right Rev. Lord Bishop of Salisbury, Dr. Neville Lovett, D.D. on 21 July 1939. The new Lifeboat was funded from the legacy presented to the Institution by a gentleman of London and Leicester named Lumb. "Jesse Lumb"'s service at Bembridge ended in 1970. She then spent some years in the RNLI relief fleet before being acquired by the Imperial War Museum and placed on display at the museum's branch at Duxford in Cambridgeshire. She became part of the National Historic Fleet in August 1999, with certificate number 1759. In 1964 the RNLI established an inshore lifeboat service which became part of the Bembridge station and utilised the 1867 boathouse at Lane end to house the "D"-class ILB. The boathouse was once again altered and improved to accommodate a new lifeboat. The new lifeboat was the  which served on station from 1970 until 1978.

In 1994 further improvements were made to the station with vital major repairs made to the slipway. The old station used for the inshore boat at lane end had work carried out in the roof space to create space for improved crew facilities. In 2009 a new lifeboat was to be placed on station which needed major re-development of the offshore boathouse which would involve the building of a completely new boathouse. The Bembridge station launched an appeal to the public with the aim of raising £1 million towards the projected £10 million required for the station and new lifeboat. Demolition of the old station began in May 2009. The old Tyne-class "Max Aitken III" was retired to the relief fleet and the station was allocated the to cover the station whilst the new station was built.
