Is it delamination or worse?

Post subject:  Is it delamination or worse?
I have read the instructions on repairing delamination; the bleeder holes and injecting resin. Yesterday I did something stupid. I planted a knee between the starboard shroud and the centerboard, heard a loud crack and felt the deck give. There was no visible sign of anything. I sat there a few minutes later and heard more "seperation", still nothing visible on the deck. Have I just created the classic soft spot? Should I use the delam method to fix it? Anyone want to give me a grand for my boat?

Certainly worth a try to fit it. Sounds like you cracked the laminate somehow. Possibly fractured the inside layer, but if the deck feels soft now... likely a delamination for sure.

I just had a very similar experience on my H17. My soft spot was from a misplaced foot between the center board and the rear cross bar. I thought it was a classic soft spot from delamination. I tried to fix the spot by drilling the holes and injecting resin. This just didn’t work. I couldn’t get the resin to even go in the holes. I finally installed an access port in the center of the soft spot. When I examined the piece of decking I removed in installing the port I found that the inner fiber glass layer had split. I repaired the crack by applying 3 or 4 layers of fiber glass.

That is exactly what just happened to me. I went out today drilled the holes and nothing would go in. One hole though had no glass on the bottom side. My drill went from foam to air. I am convinced the inner skin is ruptured.

I have the access ports to install. I will In stall them this weekend. I am going to try something different involving strips of teak.

I would keep the repair as simple as possible. My original plan to repair my soft spot was pretty elaborate. When I realized it was all caused by a single split in the inside layer I flipped the boat over and applied 3 or 4 layers of fiberglass over the split. So far the deck is as solid as ever.

I will install the inspection port tomorrow and feel around. You may have hit on it. Thanks

OK so the git rot did nothing because the inner deck cracked but there was no de-lamination. Someone said turn it over and add glass. This is difficult but made easier by the wings. I added 5" inspection ports to access the area. I only had it up on its wings for a couple of days.
