Hello lancquin56. I've have the earlier version 27 I just replaced the woodwork in. Rotted bulkheads. The procedure I used can be found under bigger boats, 'And so it begins' thread page 3 on 11-7-2010. While the 27 and 272 are different they do share many similarities. Best wishes going forward. By the way avoid my blunder and make sure you get a structural marine plywood and not a decorative marine plywood. I got to do it twice because of that.
