Solent-class lifeboat
The ''Solent''-class lifeboat was essentially a steel-hulled version of the 48ft 6in self-righting lifeboat and was sometimes referred to as the ''Mark III''.〔Rescue at Sea – An International History of Lifesaving, Coastal Rescue Craft and Organisations. Author: Evans, Clayton. Publisher: Conway Maritime Press – Chrysalis Books Plc. 2003. Work= Part II, Chapter 19 – To Right or Not to Right? Page 161. ISBN 0 85177 934 4〕 Solent Operational Numbers followed on from the first three 48ft 6in Oakleys and were interrupted by the last two Oakleys (48-12 and 48-13). The operational numbers of the ''Solent''-class had three digits in the suffix to indicate a metal hull (as with Clyde, Waveney, Thames, Tyne classes, one Arun class and the first eleven Merseys). Two digits indicates a wooden, GRP or FRC hull.
== Description ==
Apart from tkhe steel hull the principal difference to the wooden hulled Oakley was the elimination of the complicated water ballast self-righting system; the Solent derived its self-righting capability from its watertight superstructure. The class was the last design of the traditional displacement-type lifeboat to come from the drawing boards of the RNLI.〔 There were (unofficial) ''Mark I'' and ''Mark II'' versions of the class, the first eight boats having a vertical steering wheel with wheelhouse access via sliding doors at the forward end of the wheelhouse on each side, while the last three has a seated steering position with hinged wheelhouse doors at the after end of the wheelhouse. The ''Mark II'' entered service in 1972.〔 The first four boats (ON 1007-1010) and the last three (ON 1019-1021) were built at Cowes by Groves & Guttridge. The second four (ON 1011-1014) were built at Gosport by Camper & Nicholson.
