Never Give Up
Bill,I sympathize with you. I chased leaks all over my 1995 29.5, which I purchased new. Always water in the bilge, mildew on the headliner, damaged cushions, etc, etc.I spent two months last spring and finally got her watertight.My beloved Partner and I finally weakened, and dug out all of the caulk around the rub-rail (.. how much must she love me, eh?..) and refilled with 3M marine caulk. Using a smoothing tool, we ended up with a visually appealing result, and all of leaks disappeared.We had fixed all the obvious canidates, but water that enters a defective rubrail will travel up to 29.5 feet before it find a means of ingress. The Seal between upper and lower halves of the hull is NOT PERFECT - despite what the Hunter Engineers will tell you.The only place I have yet to find a permanent fix for is the area where the anchor locker retaining latch enters the starboard side of the hull, where Hunter very kindly drilled a through hole with no means of sealing!It was a brutal couple of months, but I do now have a permanently dry boat, and we use ours constantly.If you haven't replaced the Caulk, you may want to try that as a last resort. I wouldn't even contemplate a removal of the rub-rail itself, as reinstallation is difficult, and the simpler method solves the problem.
