1. Tools (saws, drill, etc.)
4. Basic woodworking skills
I didn't have an official plan to go by. I knew about how wide and how long i wanted to make the thing. I wanted to be able to get all the main pieces of wood out of standard 4x8 sheets of plywood.
I learned quite a bit doing this and will try to add as many tips and such as i go. The first is that mostly everyone will suggest using marine grade plywood etc. but i did not. This boat is not built for posterity. It was built for the challenge of doing it and to do a little bit of lake fishing. If it lasts 2 years i will be more than happy. I have used it and it is functional. Not all that pretty, but i bought cheaper materials. If you want it to look nice then at the least buy sanded ply.
If you're concerned about costs then here is tip one. Do not employ the stitch and glue method. Its basically a way to avoid having to be a good wood worker. You can have rough sloppy cuts and still make a go of it. The idea is that you're using epoxy fiberglass to weld a bunch of plywood together. For my second boat I am using lumber to join the sheets together and i will probably save myself several hundred $'s. Epoxy is EXPENSIVE and i probably saved myself a lot by practicing the method. And for gods sake use epoxy. Polyester resin will do the job, and its much cheaper, but its really finnicky to mix and the fumes are extremely toxic.
System Three Epoxies has a "book" called "The Epoxy Book" which i highly reccomend. Give it a look.
Lastly while I was not working off a strict plan, you should at least have an idea of what you want. I went to local lake and rented a row boat. The sides, back and front were about 16" high and about 4' wide so i decided to use those dimensions. And the sides and back were to be cut from a single sheet so it could only be 8' long max. So now to make a box 8' x 4' x 16" with some tweaking to make it boat like! Lets go...
