For what it's worth, I bought a couple of sheets of 12mm polycarbonate cut approximately to size from an eBay supplier. Milled out the rebated overlap with a router, put them together on the bench, then drew round my old cracked 9mm acrylic boards, jigsawed closer to the line, and trimmed off the last bit with the router (the jigsaw tends to make a rough melty edge, the router cuts cleanly).
They fit perfectly on the boat, better than the old ones due to the extra thickness, and must be significantly stronger.

If you want to cut acrylic with a jigsaw it is worth getting blades which are designed to cut plastic (Bosch make them, but I'm sure others do too). The blades have no set on the teeth. They give a remarkably clean cut.
But I agree that a router is easier to use. I can never get an accurate straight line with a jigsaw.
