Thanks Karlis,
I'm a big fan of SketchUp and have become reasonable proficient with it over the years drawing Triloboats as well as my own ideas. This boat is mainly a Triloboat but does have some unique differences such as full length longitudinal stringers.
I am keeping tabs of my costs so far and have divided them between the actual boat materials, and everything else such as tools, space rental, consumables and so forth. As far as boat materials so far I've gotten hold of a pile of Indonesian mahogany pallet material that will come in real handy for finishing out. There is quite a lot of it - probably more than I need - and that was a few hundred dollars. A lift of 1/2 inch fir marine ply (66 sheets) and 150 structural fir 2x4 x 16 feet was $5500 delivered to the house. I have yet to buy any adhesives (PL Premium and epoxy) but once I do I will have enough to pretty much build the structure.
I'll post progress in a more appropriate forum (?) and once I've gone a little further I'd be happy to have you out for a look!
