When i had the mast unstepped, there was about 1/4'' gap between cabin top and beam, so filled with epoxy, and then added this 2'' alum. angle iron, through bolted. Bolted new hinge down through the beam and angle. Will now have two nuts for a nut head gouger, but couldn't figure out any other way to make it stout. The hinge has to rip out the whole piece of 2'' angle now, which ought to make as big a mess as you have someday! Here's a shot of the angle, and the hinge.
