Hi Walter,
I've just printed the plans off at a couple of different scales....
One would give a model 28" long, with a beam of 4" and over the sponsons 7"
The larger one would give a model 38" long with a beam of 5" and 9" over the sponsons...
I think the larger one would be better, and I should have enough materials here to build a hull (or two as I'd like one too), so if I knocked up a couple of hulls, and do the basic superstructure, would you be prepared to do the finishing and fitting out as a joint project?
Regards
Eddy
