Mine is 1 year old and I added float bags.
I did a pool trial today to get back in, and to test the bulkheads. I remember from last year that I had a leaky bulkhead and I now know that the rear bulk head is the one. Since I have the float bags, I could probably remove it altogether and just use the float bag to the tip. I would cut it out, and then leave about an inch around, so that it still provides structure, and acts more like a rib that a true bulk head. I have two of the 6" round hatches and they could also be the thing that leaks. Although, the forward one was a little wet, but the aft was full.
What's your advice? Try to seal the leaky one? Or remove it and just use the float bag?
