The collection also contains the last remaining SR.N4 craft, the world's largest civil hovercraft, which has been laid up in Lee-on-the-Solent since cross-Channel services ceased on 1 October 2000.

The museum houses the world's largest library of documents, publications, film, video, photographs and drawings on hovercraft, all of which is available for research by prior arrangement.

A number of hovercraft manufacturers have deposited their complete archives with the museum for safekeeping, thus swelling this important repository of information.

The museum reopened in January 2016 after being closed for essential structural building work over nearly two years.

Shortly afterwards the remaining SR.N4 craft came under threat of scrapping when the site owners, the Homes and Communities Agency, proposed the redevelopment of the land.
