Does anyone have any tips on the best ways to cut marine ply (6, 9 and
12mm)? In particular I want to cut curved 8' boards for a dinghy. So I
guessing that a band saw is a good bet but I don't have one. Are there
any other methods that can produce good results?

Pre-saw with an electrical jig saw, outside the lines. Nail a batten down on
the lines and use a router with trimming bit, rolling along the batten.
Makes a Perfect cut.

You can also tack the batten down first and slide the jigsaw aloing it, with
a block screwed under the sole in such a position that the blade cuts about
1/8 to 1/4" from the batten.
See my website at
