Transom door repair help

[wileecoyote]

This is a pic of my transom door. It looks like there may be a small block of wood near where the hindge bolts up, other than that I can't be sure. My question is this. I don't want to rip the whole door apart and replace everything, realisticly, if I let the door sit, it won't dry out but can I grind back the fiberglass and rejoin it? I don't think the wood is even wet, due to the location it rarely gets wet anyhow. I know everything gets moisture, but I don't think is has much more than atmospheric moisture.

There is more than atmospheric moisture in there for the fiberglass to have split apart in that manner. I would cut the outer skin off where it is loose already, remove the wood, dry the fiberglass, and only then reinforce (preferably without any wood this time), repair, and re-gelcoat the entire door.
