WOW , they take a lot of work hu , i have a brother who spent a lot of years working for Doral boats and one of his jobs was replacing transoms , on a boat like ours they cut the fiberglass on the back side or may be better said on the inside of the boat in order to remove all the rotten wood then fiberglass it back in , that way it looks like it was never touched ,, i've watch him over the years do a few , lucky for me he rents an apartment from me and has offered to replace the floor in my boat once its in my shop , i gutted it last fall and found the floor to be bad under the seats . you have your boat looking real good , looks like its finshed if you did'nt know better .
