When I did my bulkhead I was advised to put a temporary support in if I the bulkhead was going to be removed for a while. Based on that advise it might be best to do one bulkhead at a time to help maintain the hull and cabin's shape
ahh... the hidden screw.. oh those hidden screws!!!! In some cases it seems like they install the screw first and then screw the wood into it!Yeah, mine’s down too, on the trailer. I just found the hidden screw....
As is usually the case DrJudyB is right. Always listen to the doctorThat bulkhead is a very important link in the system that holds the rig up. If it’s got any rot, it should be replaced. Take an ice pick to it and see if it’s soft. It it is soft, it’s no longer strong.
Here’s a couple of pictures of replacing the bulkhead on my old 1977 Catalina 27, which has the same type of bulkhead structure as your boat.
