Yes the Dubarry looks very similar and it says it was based on a thorneycroft.These were diagonally planked as were the full sized ones in the pics.Did not realise they were twin screw as they were afloat!.The chine hull was easier.The engine (A Westbury hybrid with bent pushrods!)is not very powerful but still gives more than scale speed.The bottom end is Westbury mated to an unknown top end,spark is by a car coil and 6v battery and allows a really slow tickover you can almost count the revs and a reliable pick up but seems to be flat out at 3500 rpm so with a bigish prop seems a good motor for the boat just wish I could stop it leaking oil!(crankcase pressure even with a 1/4" breather!)

What a lovely shaped boat I bet that cut through the water with ease.

Could be the River Cruiser Dubarry, plans are still available.

Don't know anything about them but I love the lines of the model. is it scratch built or did it come as as a kit?
