When we cut a flush hatch we just used the bosch jig saw with a new blade. We started the cut by drilling a series of holes witha 1/16 bit to get the blade in and used masking tape to prevent splintering. We also used a piece of a wood batten as a straight edge for the straight parts of the cut. The corners were cut free hand. We would bend the batten to conform to the curvature of the deck. this was best done with two people one to hold the straight edge,the other to use the saw. a little sand paper to smooth the edges and your in business.
