Okay then, we'll start with the wood. I'm pretty sure Roger has all the woods called out on the plan but we will go over them anyway. You will need three thicknesses of plywood, 1/16th, 1/8th (FIVE PLY) and 1/4(FIVE PLY). Stay away from the home improvement center plywoods. The 1/4 is only 3 ply and usually has voids in it(not good for boats). Also, stay away from doorskin for the 1/8th(been there, done that, not a good choise). If you can find a source of AIRCRAFT GRADE plywoods in large sheets, get some. If not, mail order or the LHS will have to do. You will need one sheet of 1/4X12X24 for the transoms(both the stern and sponsons), two sheets of 1/8thX12X48 for the engine bay walls, the sponson insides, the sponson edge frames and a strut doubler in the stern area. The rest of the hull is 1/16th ply, so you will need five to six sheets of 1/16X12X48 for the cross frames and skin. You will need to get twelve 1/4 square stock Spruce for stringers as well. Four need to be 48 inches long, the rest can be 36 inches. These will be used for glue blocks and for strengthening the hull. I also tend to use 1/8th spruce at my 90 degree glue joints when glueing 1/16th framing where it's not notched to fit. One other piece of wood you will need is a piece of pine or fir 2X4. This is used to shape the bow blocks at the front of the ram wing, so plan on some serious shaping to get them to what you want. This should get you to the point of being ready to put in the systems(fuel, radio, cooling, drive), which is where my boat is(pictured below)
