Hi Woody Boaters, we bought this at a farm sale and saved it from certain destruction as the only other bidders were scrap dealers who wanted the trailer and the dead 2.0ltr Ford “Pinto” engine that came with it.We do know the jet unit is about 1957-58 and was built by Dowty marine in the UK under license from Hamiltons in New Zealand.
As this is all wood we wondered if any Hamilton boats made it to the U.K for evaluation or as models for the fiberglass molds.The company that made the hulls for Dowty still exists but there are no records surviving after a fire earlier this year. A Dowty expert who’s restored a couple and also runs the oldspeedboats.co.uk website has had a look at it a made some observations.
He said the hull resembled early Hamilton types but wouldn’t have had the ribs running under the hull,also the transom has been modified (see pic from inside for original profile).
There is also some modification to the steering gear compared to his and he wonders if it may have had the earlier jet unit in it originally which may account for the cut-away in the centre of the transom. We have contacted Hamilton Marine division but they aren’t sure. Some people suggested it may have started out as an outboard but the general layout seems to suggest it was in-board and the original mounting points look long enough for the straight six Ford engine like the Dowty’s had. Does it resemble any obscure U.S built boats?
