A tip I read on one of the woodworking forums was to support large
plywood panels with a piece of inexpensive styrofoam insulation sheet. Although it wasn't exactly cheap (~$14) it was extremely
helpful in cutting the thin 1/4" and 3/8" plywood sheets. You can cut the panel and into the foam without worrying about hitting
any of your support underneath.
There's not much else to describe in this step. Cutting wood is
a basic step and I took my time to make sure the dimensions and layouts were correct before making a cut. On this particular
boat you can save time by doubling up with 2 sheets of 1/4" plywood to cut out sections of the bottom and side panels.
The tools used were a pair of folding workbenches, strongback, foam sheet, jig saw, circular saw, and a bandsaw, and an RO sander to smooth the rough edges on the fresh cut wood.
