thanks for the positive feedback guys I went down the dumas road but still no response. Have not tried newton yet but i received a set of plans via e mail of a hyrdomite micro hydroplane which has helped clear up a few grey areas.Hydro when you said all the long frames out of 1/8 do you mean to include the long sponson piece that forms the inside of the tunnel or is it just the stringers that form the ribs of the sponsons.Why are the transoms out of 1/4 is it because the hardware is attached to it.I think I am on the right track
