Vosper Firefloat Mk. 1
Well I have now exhausted my search for what my boat is modelled on, having communicated with Terry Holtham , an acknowledge expert in the field of RAF Marine Craft, he says it bears an uncanny resemblance to an official Vosper drawing of the Mk1 version of the 46ft Firefloat and goes on to say that the only difference really is the wheelhouse detail, and probably the stern (transom) which looks more like a MiamI Boat Co. High Speed Launch.
What I have now done and am still in the process of, is to re-create my boat as a working drawing. This has entailed taking exact dimensions of my model and then recreating as a working drawing using AutoCAD. I have completed all the plans and elevations of the hull and I now have left the 'skeleton' frame and superstructure to do.
Now, here is the question. My model measures just under 34 inches in 'old money' and of course my drawing in AutoCAD is life size for the model. if I was to scale the model up to say 48 inches in length, would I need to increase the size/thickness of the stringers, keel, frames, etc.. Also my model is built from balsa, so if I were to build a new one at this size could I keep to the use of balsa as that would be lighter than ply ?
Another question is what would I do about motor size and prop ? At the moment I have a Speed 600 Eco motor and a 30mm prop.
Any advice would be appreciated.
