ST437 is twin engined with a hard-chine; a shape which means the boat can operate at sea in any weather conditions and at high speed for rescue work. 437 is double diagonal mahogany with a fabric inter-lining beneath the waterline using a boiled linseed oil and varnish mixture and her sides are only single planking; but still using bronze and copper screws and rivets. The 200 Class seaplane tender was the origin of all the future A/SR vessels - the Mk1 (ST437 et al), Mk1A, the larger 63' Vosper HSL, the 'Whaleback' and the 'Dorset and Hants'. Most of these vessels were decommissioned shortly after the war, although some continued in service until the Sixties.
The vessel has not been to sea since May 2015 and was recently acquired by her present owner who plans to restore her to her original condition.
