Hi

Steamer it seem like you know what you are looking for , you know what
type of hull and you proberly have an idea about what mid section shape
you want ----- why don't you just try put down the lines yourself in a
free CAD program such as IntelliCAD , it is not that difficult,
What could be difficult is to decide what materials to use ,what
building technike that is fit for the type of boat , also when you find
plans are these made for the building technike you will chose ?
Most amature builders find that one of the most important issues with a
build, is to have a strong building jig, something that allow you to
shape the paneling without fiddeling. Now the tradisional boat plans is
just sections cut thru a 3D form, many detail issues are left to be
solved by the builders experimence , most plans do not tell you that
the first plank will be a major challance or that the third plank ask
extra care as it cover forms that go from convex to concave forms on
the hull ------ now what not so many seem to know is, that all these
troubles are solved if the boat have been projected in a CAD program
--- you see ,when you unfold the paneling from a 3D model, you see
these difficult shapes that you have to put into the individual plank
or panel so to end up with a hull shape without to many sharp edges or
"impossible" details , details that can ruin the whole project if you
are not prepared for them.
So my advise is that you rather go into detail now and spend those few
extra hours, to acturly get what you want, instead of trusting just any
neat design just becaurse there are a simple front, side and top
drawing.
