Hi all, I have discovered a major leak in the cabin top and down my support post in my M-23. The deck is slightly deformed and the base of the support post is slightly pushed into the cabin floor from one of the previous owners perhaps over tightening the rigging. I may be able to simply caulk the tabernacle and bolts but I probably should fix the deck. What I am planning is to figure out if the base of the support post is stable (I assume it is on the base of the hull at this point but cannot see under the floor) and to put a solid aluminum plate underneath the tabernacle that directly sits on the support post. I plan getting the plate made by emachineshop.com. Then glass the plate into the deck and cover with Kiwi grip or some cosmetic approach. I would appreciate any suggestions on this project that anyone might have. Thanks Robbin M-23
