The bottom of the bulkhead has rotted pretty badly in the head About 3 inches up or so. Can I just cut this portion out and fiberglass the remaining bottom of the bulkhead to the floor? It is rotted from water sitting in the floor pan from showers is my guess. It has done it in the other head also. It is a 78 Irwin 37 CC. I see no need in scarfing a new piece in or replacing the hole bulkhead. By bringing the floor-pan up the wall 4 inches or so I will be eliminate the problem for good.

The question is was the bulkhead attached to the hull or to the floor pan. If it was attached to the hull, and you're attaching it to the floor pan then the repair won't be sufficient, since you're not securing it properly and transferring the loads to the hull as it was doing originally...

I would fiberglass both sides of the bulkhead. One side to the head floor, and the other side to the cabin floor. Going up the wall 4 inches or so on each side.

Yes, but if the bulkhead went down to the hull, instead of the cabin sole pan liners, your repair isn't going to be doing the same thing the original bulkhead was doing. If the original bulkhead went down, past the pan liners, to the hull, the repair needs to do the same.

Most of the wood is gone and it seems as if it just went down to the cabin sole pan liners and sat on top of that. Probable glued to the sole. I would just cut the bad area out and fiberglass it all up. I will be painting the bulkhead white later anyway. Will this make to strong of a structure/bulkhead? Thanks for your input.

If you cut out the rot, is there a place on the floorpan where the bulkhead was fastened before it rotted? If yes, I would want some sort of similar mechanical fastening in addition to the fiberglass laminate. If the evidence suggests that the bulkhead just sat on the pan, it may have done so because it is a non structural member intended to move seperately from the pan. In that case, you would not want to join the two.

no pics at this time. I bought the boat down in Miami and will be going to bring it up to Panama City Fl at the end of the month. Just doing research on the things I found during the survey.
