This is our first Northern California winter with our 1987 C25 WK so I wasn’t sure what to expect in possible leaks. Through plenty of storms, she has stayed dry from bow to companionway inside. But a small puddle of water (couple of ounces) that pools in the aft quarter berth is driving me nuts. I can find no leaks on any hull fittings, chainplates, winches etc. I’ve spread chalk inside the hull and it stays bone dry. I’ve caulked the scuppers. Checked the dumpster (port locker) and it is dry. After the last storm I noticed the underside bottom of the cockpit, inside the boat, had a thin coating of water, kinda like you’d see on the inside of a single-pane house window. Is it possible my few ounces of water could be dripping from condensation? Has anyone had a similar issue? Many thanks in advance.

On Catalina boats of our vintage, the companionway is much less inclined than vertical. This allows rain water to leak into our boats through the companionway, despite the hatchboards being in place. This could be the source of your leak.
I keep a pot on the settee, to starboard and just aft of the companionway stairs to collect drips. Other folks have a cover fashioned for the companionway to ward off this leak and protect their hatchboards’ finish.

Thanks. I should have mentioned, I do have a waterproof cover that covers the cabin top and hatch boards fully. Don’t see any leaks there, but farther aft.

Mine collected small amounts of water after really heavy rain at the same spot as well. I observed that the water was dripping from the light fixture. Water was following the wire from somewhere else. The only area that appeared to make sense was a possible leak in/around the openings under the winch in the coaming. I cleaned and enlarged the drains in the starboard coaming openings under the winches, replaced the light fixture and the problem appears (for six years now) to have been resolved. With water, especially on boats, the source may be nowhere near the observed symptom!

One of my stanchions, the one that everybody grabs when boarding the boat right near my quarterberth, leaks from time to time and leaves a brown trail down the side of the inner hull. I’ve rededded it for the umpteenth time but it still leaks after a big storm. Water running off from the bow and cabin tops all converge at that point, so there’s plenty of flow and the water has plenty of “head” / pressure to push through. That’s why a cabintop cover won’t prevent it leaking. That stanchion, and the jib block track, are two potential sources.

Thanks for all the input! I did check the light and every other nearby wiring spot, but they are dry. My coaming compartments in the cockpit seem to be self-contained with no drain (they fill with water in heavy rains) so can’t see it coming from there. If it were from the stanchion or jib track I would think it would show on the chalk I put at the top of the inside hull?

You could try removing everything from the berth then sit in there and have a friend douse the outside with a hose or even a lawn sprinkler You should see something sooner or later. The lawn sprinkler method you could let run for as long as it takes untill the leak shows it's ugly head. If you get enough water for a long enough time it should be visible.

The cockpit sole may have numerous, tiny cracks that have let water into the plywood and then out through other cracks in the quarterberth ceiling. There was a post on the Forum years ago in which it was refurbished by cutting around the edges and saving the top fiberglass/gelcoat layer, digging out the wet, rotten plywood core, and then rebuilding the core with new material. The original non-skid sole was then glassed back into place. It seemed to be a big job as it was described.
A symptom of this condition may be that you have a spongy, soft cockpit sole in one or more spots. It would be simple to run a hose into the cockpit, cover the scuppers temporarily, and see if you get water below.

You don't mention a port-light in the quarter-berth, so cannot make any assumptions, but on our boat (#5972), a failed seal around the port-light proved the source of an intermittent leak in the QB.

None back there and others seem tight and dry.

I tried caulking the scuppers for water collecting all the way aft to no avail and thought the source lay elsewhere. I eventually cut and removed the scupper (another thread) and discovered that it was installed without bedding. I reinstalled the scupper with bedding and repaired the cut as a temporary measure and the leak disappeared. Is the shelf at the aft end of the quarterberth wet? That is where water will collect and run down if the scuppers leak. How far aft does the water appear? Finding leaks is always a challenge, but staying aboard during a heavy rain or the hose spraying is a good method.

Lots of crawling with a lantern showed the shelf at the aft end dry. Water collects about midway between the companionway steps and the transom. Thought it might be leaking into, and out of, one of two hatches under starboard cockpit seat, accessible from inside. Pulled wood hatch covers and they are dry too. Guess the hose is the best option.

I have a 89' WK with the same problem. Yes, Seth is correct. During a heavy thunderstorm last month, I track my leak down to water thru the companionway. And yes, I too have a companionway cover. The water runs down the track on which the crib boards rest to the threshold. From there it wicks up under the threshold up hill and over the lip, into the cabin along the side and down to the aft berth. It was truly amazing to watch. I fixed the problem by pulling the threshold, and butyl tape along the very upper lip, so that any water that gets under the threshold will drain down into the cockpit and not wick up and over the lip into the cabin.
The gravity-defying powers of water never cease to amaze me. I was sure the c-way was sealed tight. But I will check that out. Thanks!

Come to think of it, I have my DSC-VHF radio mounted to the left of the companionway stairs just inside the quarterberth but on the underside if the cockpit seat. It will get wet from time to time. I mounted a flat plastic barrier piece over the top of the radio (it was a Tupperware top) and now the drips fall off the lid then down on the floor instead of in the radio. I never tried to figure out where the water came from as I suspected the crib board slats or the cabintop cover. Maybe you can use a piece of plastic wrap to cover the slats or weatherstripping to seal the cracks.
Similar problem, opened up the battery compartment to find about an inch of water :) Thinking about drilling a drain hole for drainage into the bilge (I keep my batteries in their own cases, and they're AGM anyway).
I know my windows leak, though. Going to try and do something about that. Hasn't been so bad.
Going to try and sew something together during the season to cover the teak + companionway. I figure some good wax or other waterproofing should hold up adequately. We'll see.
