sail slide track

[howard]

we have a 422 but would think some things are similar. over the last week with all the rain we are finding all the leaks. the question i have is about the sail slide track. ours sits on top of the cap rail, and i think that this is the deck to hull joint as well. is there a wood core in there are would it be fiberglass. how would be the best way to reseal this. any and all comments will be welcomed.
thanks all

My 424 has solid glass under the teak toe-rail. I’ve had no leaks there despite high loads on the track for over 30 years. I’d be surprised to find that yours leaks, but nothing is impossible. Are you sure that the track leaks or could the leak be elsewhere? I’ve had leaks under the stanchions and the chain-plates must be rebedded every few years. Could they be the source of your leak?

If your leak is under the toe-rail, the question is “is the track leaking or is it the hull-to-deck joint?” Sealing the track would be fairly straightforward if you can get at the fasteners. The hull-to-deck joint would be much more difficult. I believe that Pearson used 5200 to bond the hull and deck. The toe-rail cap is screwed into this using stainless screws set with either polysulfide or silicone sealant. The track is then through-bolted to the rail cap. There are no other fasteners at the deck joint.

i am sure the one of the leaks is the sail track. all the bolts holding the track down are loose, very loose. i tightened some of them and the leaking slowed. the biggest worry i had was if possibly Pearson used a wood spacer or something in there that may be rotting and me not know it. thanks for the info about the hull to deck joint being just fiberglass, that makes the job easier.
thanks

Howard,
+1 on Rich's comments.  Although the track could be the leak source the stantions, bow and stern pulpits are also potential sources.  I had one deck leak on Sarah that I fought for over a year.  During heavy rains I would get a tablespoon or so of water in one locker.  I removed all of the vinyl covering in that locker and could see the water was coming down one of the deck flange screws – from the hull/deck joint.  I finally found the source when I removed the bow pulpit to run some electrical wire and found there was no sealant under those stanchions, which bolt through the hull deck joint.  After I sealed those stanchions my leak disappeared.
Once water gets into the hull-deck joint it can come out almost anywhere, usually through one of those screws. 
Just got your last update.  There does not appear to be any spacer in the deck joint.  The only wood is on the cap rail.
