Sorry for a late reply Stan.
All good questions, yet to be answered, mainly because I don't know yet.
My main task is firstly is to transpose the plans out of the book and into autoCAD, this is taking a long time as each when cross referenced with another drawing is out? So it is a constant battle to decipher which plan is good and go from there. The plans are being done full scale, then scaled down to whichever scale you want. Latest breakthrough is getting the deck plan correct, this can now be transposed back to the body plan which can then be adjusted accordingly. Hard, time consuming work, but worth it.
It will have to be a split hull, 3.6M is far too big to handle in one go. Plank on frame, fibreglass, metal, plastic........not decided on material yet, but a lot of ideas floating about in my head. Once I have made some headway, will post an update.
ps, maybe worth seeing how much body plan from NMM is, that will clarify any vagueness in other plans?
Any one had dealings with NMM?
