One extra hint. When cutting splintery wood like meranti. Lay a batten
along the finish cut line and score the top side with a crate knife before
starting the cut with an up cutting saw like a circular or jigsaw. It
prevents chipping of the face veneer so you will end up with a much cleaner
edge. Not needed with a reasonably fine toothed a band saw.

Saw outside the line and trim to it with a plane, router or belt sander.
For long slow curves I use a circular saw set just deeper than the sheet. I
do the gross trimming with a power plane and finish up with a low angle
block plane.

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?

Thanks
