Leaking roof in way of "smoke stack". NT 32-238
Greetings from ESS-KAY Yards, Brewerton, NY, a great place to store your vessel for the winter or just stop for fuel, pump-out, parts, and grocery/laundry run.
We are now back afloat after the long winter slumber. Today was the first rain storm, and we had a leak around one or two of the screws in the ceiling above the steps leading down from the pilot house into the main salon. The photos do not show much, (fiberglass, 1/4" plywood and foam-backed headliner) except where we stopped the leak last year using Life Caulk. We just removed one of the screws that was leaking but cannot figure out what the screws actually do (other than leak). We are tempted to fill the screw holes with epoxy, but are concerned that this will only mask the problem and make it worse in the longer term.
Has anyone encountered this problem and what remedy did you use?

Ours was leaking at the same place. I removed the stack, removed and replaced caulking between the pilothouse and upper deck, with no further issues. Note that there is no sealant between stack and pilothouse roof so water can run through. When reinstalling I only sealed at the screw points holding the stack for water to exit. I think I used 3m 4000 which yellowed somewhat and will use 3m 4000 uv, lifecaulk or other uv protected sealant if needed again.

Hi, Eric, and many thanks for your reply. We recaulked the join using Life Caulk between the pilothouse and upper deck last year. Used butyl tape to seal the stack to upper deck. It appears that the caulking has failed as we were leak-free from June to October when Bessie returned to dry covered storage for the winter. Will report what we discovered.
Many thanks,

The seam between the boat deck and pilot house/ flybridge is prone to leak. The core of the boat deck is balsa so the water can travel between the skins and the balsa rot. We had the upper skin removed. Then replaced balsa with synthetic core. Then that seam grounded out and cleaned. Then the junction glassed. Then gelcoat. As the boat works and with time caulk or epoxy will usually fail. Would take a moisture meter and find out where that water has gone to. Only then can you plan the extent and nature of a repair that will last.
Did you seal the entire stack base or just the screws? Also I have read where
butyl is recommended for bolted parts, but not screwed parts due to its low adhesive qualities. Perhaps the butyl is holding water and leaks at the screw penetrations.
I look forward to hearing what you find.

That's very good advice. Many thanks. We will check for water penetration with a moisture meter.

Hi Harry,
I also, filled the joint between the pilothouse and the upper deck with fiberglass to eliminate the need to "stay on top" of this large joint filled with caulk. However, do not seal the entire base of the "stack". It is designed to allow the water to "run out" of this area. Water from the pilothouse roof is free to run into the base area (of the stack), and if this area is sealed, the water can accumulate here. In this area there are not only the screws used to hold the stack, but also the penetration of several wires entering the boat, relying on sealant to "keep the water out" (at least on my boat).
If desired, you can drill out (larger hole) where each screw holding the stack goes, and fill the larger hole with epoxy, and later attach the screws to the epoxy (still) sealing with Sikaflex or whatever sealant you like. Should a leak develop at a screw, this method will eliminate any core damage, but periodic removal and recaulking the screws will still be required to prevent any water penetration into the interior.
Hopefully you have not sustained any significant core damage to your upper deck. Any (roof) penetrations need to be maintained regularly to avoid what could be expensive (of if DIY time consuming) repairs.
Good luck with this,

Hi, Tom, great to hear from you. As soon as it stops raining and we can dry the deck we will drill out the stack screw holes, check for water-logged core, and if dry, will epoxy bolts (head down) into the holes and attach the stack with acorn nuts. That will eliminate the screw holes in the deck. Sealing the pilot house to deck joint with fiberglass is an excellent idea and we will do that also. Thanks for tip about not sealing the stack to the deck, to allow water to flow through. Another excellent suggestion.
Thank goodness for all of the helpful members of SENTOA! Will post our results.
