I am a bit shaky with the jigsaw but managed to stick pretty close to the lines and make a good fit. You can see the 2 sets of lines - the first set was from the cardboard template. After sectioning the main straight cuts, we picked up the partially finished transom and test fit it in the boat, using the fiberglass hull as a new guide for marking out the splashwell section. Quite a bit of error, I am glad we double checked - forgot to take a picture of it while doing it, though.
