Thank you all for the helpful responses. I did have extensive leaking from under the toerail when first getting the boat 5 years ago and mostly stopped it by running a bead of 5200 around the inner perimeter of the rail and figured that was a temporary fix. That 5200 had now degraded and is cracking, I'm assuming due to UV exposure.
My boat has been a Florida boat since new and I'm guessing the heat has had an affect on the deck/hull seal -- the original butyl sealant is weeping out and dripping down onto the inner hull (big mess); it would be an impossible job to remove the deck to replace. Don't know why I never thought to check the bolt tightness before it being mentioned in your replies; they are almost all finger-loose, I'm assuming because of the settling of the deck due to the loss of the original deck/hull sealant. I haven't seen any weeping of the sealant between the toerail and deck I'm currently prepping the boat for deck/cabin/cockpit painting and have all deck hardware removed and will re-bed when refitting -- now is the time to tackle this. I'm thinking now my options are to go with my original plan of total R&R of the rail -- or to pull the bolts a few at a time, work some fresh butyl into the hole and screw the bolt back in through the sealant, tighten them properly, and back that up with another bead of calk on the deck/rail if needed (and redo that every few years as needed). Thoughts . . .? Last year I rebuilt the kingpost support in the bilge, reinforced the bulkheads for the chain plates and did some deck repair where the chain plates went through, did some glass/gelcoat work around the fore hatch where it had deformed due to the mast step setteling, made a new main hatch slider and cockpit locker rails. I enjoy bringing her back to shape, but I do enjoy sailing more than working on her. I figure these projects will be good for another few decades.
