Riddle me this: I am slowly working my way over the deck fittings to plug small leaks in my C-25. However, there seems to be some drippage coming down the inside walls, from behind the 2" mahogany trim. My guess is that this could only come from a shoddy fit between the deck and the hull, behind that fat rubber exterior rubrail. I'm talking about rain leaks here. Has anyone dealt with this yet? Mainly, can the trim be removed from the interior and Boat-Life installed, or would one want to remove the rubrail and do the sealing from the outside?
The 'bristol' way is to remove the rub rail and re-seal the deck-hull joint. The 'cowboy' way is to run a bead of sealant around the top of the rub rail frame where it meets the hull.
I gave up on the "bead of sealant" method. It just didn't keep up with those persistant little leaks ... so after removing the entire rubrail it was shocking to see so many holes drilled into that hull to deck joint area. What on earth was Catalina thinking? I am using the access to properly fit an upgraded bow stem with anchor roller. The holes will all be filled, the area sanded smooth and a new style rubrail installed - it's the one that accepts a 3/4 to 1" lacquered synthetic rope instead of that grey rubrail. All this has to wait until I get back to the States in the fall -
We used to have the same problem. The track for the rubrail was put in with sheet metal screws. Over the years, the caulk (if there was any, we still talk about the great caulk shortage in California back in 78) has deteriorated. If you catch a good storm, or a good puff of wind, the water finds its way in there.
We removed the entire rubrail, then the track. It was a couple of years ago, but if memory serves me right, there is a screw every six to eight inches. We caulked the entire track and each screw to a fault. Then reinserted the rubrail. It seemed to stop the problem.
If I were to do it again/hindsight 20-20 I would have spent the extra scratch and bought a new rubrail.
Thanks for the dirt. Since I have more time than money, I might remove the rail in the fall and caulk. Launch date's too close for that kind of job now....
You might also want to consider the genoa tracks. For my boat, that's a more likely suspect. A leak there will also send water down from behind the 2" trim piece.
Whenever we have a good down-pour, the rain water comes off the bow and the cabin top and gets channelled into that narrow side deck between the genoa track and the cabin window. I'm guessing that the water rises above the toe rail then under the genoa track and down a bolt hole.
I'd like to pull the track and re-bed it, but with 40 odd bolts per track in really hard to get to places, that's never going to happen! I'll probably try a bead of Life Caulk along the inside where the track meets the fiberglass and hope it helps.
