I dicovered today that the transom on my 69 Thunderbird Seminole (Cathedral Hull) has rot damage. I had already planned to replace the soft spots in the deck. My question now is do I replace the transom and deck or look for another hull. It has a good 1978 Merc 175 HP Black Max engine. I could do the repairs myself. If it is best to look for another hull, how do I go about finding one? I welcome the advice of you experienced boaters.
