The Dowty Turbojet boat hull was built by H. Attril & Sons (IoW) Ltd (under licence to Dowty, Gloucester), on the Isle of Wight in the 1950’s to 1960’s and was a revelation, it was also a reasonably expensive boat at £789, which makes it at todays value worth £22888.09.

If anyone recognises the people in the boat, please let me know who they are.

The boat hull and mould designer for the UK was Fred Cooper, the well known racing boat designer, who was also involved in some of Campbell's K4 and other designs, but the jet was by Hamilton in New Zealand. The Dowty company in the UK commenced manufacture along with Buehle in Canada and Hamilton of course in New Zealand.
