Is that $156 for the 6 sheets, wow that is cheap!
I got my 4 2500mm long 4mm sheets from Boatcraft Pacific in Queensland, would have to look back to see the actual cost of the sheets, but I paid $60.00 freight. I bought 2500mm sheets as to only have the one join in the hull sides.
I have to ask in regards to your foam, what size sheets were they? Were they the white styrene foam or the denser blue coloured foam?
Also the mosquito plans you say have three different shapes, are they based on like a fay hull, a boyer hull and the pearce hull?
What stage is your boat at? how has the 3mm ply formed in terms of where the frames are, I mean not too many rises and falls in the hull skin? I know the A class were built with 3mm and didn't have many problems so there shouldn't be any reason you have.
Keep us posted, I'm very interested in homebuilt boats.
