I am in the process of rebuilding a 2900 Wellcraft Sportsbridge.Looking into adding a transom door.As for as the structer,there will be no problem.This boat has inboard engines,nothing on the transom.I been fiberglassing for 20+ years,don't look like a big job after all.What I'm looking for is the hinges to support the door.Anybody know were I can buy some?I will have to get them before I start to cut in the transom,that way I will know how I will glass is some support.
