the euro transom. it can add beam
And it can also add length. My side panels are 3 full-length plywood sheets scarphed into a single 23'-4" sheet. I planned to use 23' with 4 inches to spare. But when the forward section of side panel did not bend as severe as expected, I had to flatten the stem and use more side panel than expected.
As I fret over whether my side panels would be long enough, I saw Fithian's euro transom. I realized I could just build with what I had and if the side panels are short, they are short at the top of the transom. If needed, I could lop off the upper segment of the side panels at an angle and build a euro transom, which, BTW, looks really cool on Fith's boat.
In the end (pun intended) the side panels were long enough with no length to spare. The tip if the stem and the tip of the stern are the factory edges of the plywood. No lopping required. No euro transom this time but it is on my wish list.
