Hi
If the plans had been from a 3D model ,you could just scale and chose
the one you like best ,but cutting the stations and testing with a real
Spline ( a long strip of wood or metal ) that the lines fit swell
,----- just do it, don't vorry as if Splines fit smooth then ofcaurse
you can plank it.
Still if it was a 3D design, you could ask an application to calculate
"the inbetween" of two very different hulls ; yes if you have two 3D
models you can morph between the two ,you could stretch and scale it do
whatever youy want and then slice the waterlines ,slice the sections
and have it plot full scale.
Still just trust that you will learn from the experience ---- I know
amatures who replaced the intire planking and most ribs in an old
fishing vessel, as long as you don't try cut corners use the right
materials and don't try save stupid having the trouble with bad
materials ,then trust yourself not any Pony.
