Leak in Cabin

[dino]

We noticed on the port side along on the step up to bed under closet the rug was moldy
in a small area. We have been keeping an eye on it when it rains to see if we could see where it was coming from and it stays completely dry. I went out with a hose and tested the port windows one at a time as well as where the bow rail attaches and no leaks. When I filled to water tank the last two times we noticed it became wet. Anyone else experience this happening? I do not see any access to even see the fill and vent lines but assume that the wood panel under mattress needs to be removed. Thanks

I have experienced it but i have yet to solve it. i found that the water was entering the cabin from the forward port side port light window. I saw it pooling at the bottom of the window. It wasn't able to exit through the caulking on the window so it all came into the cabin and made its way to the floor right where you see it. Although thats where it was entering the cabin, it is not where the water was initially entering the boat. I removed the port light window and saw that the water was coming 'UP' into the window cavity between the fiberglass and the coring. The water was getting into the hull from somewhere else. I taped off and re-sealed everything that I could and still cant find it... but with the port light out, it wasn't leaking into the boat any more. I also pulled off a good section of the rub rail SS and unscrewed the rubrail itself and recaulked the screws, but that didn't help. For now I put the port light back in with a very little gap at the bottom of the window to allow the window to drain/weep. It still leaks when it rains or we washdown, but its not coming into the cabin. When we lay up for the winter, i am going to remove the entire rub rail and reseat it. IMO it is the most logical place that the water can get into the hull.

Not sure that helps any.... Good luck. please let us know how you make out, and i will do the same.

We had a 2005 390 DA. The aft cabin area floor was periodically wet. Did all kinds of spray tests with fiber optic cameras to look behind walls. Thought it was the deck railing or something else above the cabin. Worked with SeaRay and the local yard for many months. Turns out the base seal between the upper bilge and the inner cabin was faulty allowing occasional rain water the leak in. A fuel tank and the generator rest on that upper bilge floor. We were the original owner with the extended warranty so SeaRay agreed to remove the starboard engine and fuel tank and properly seal the bad joint. The floor remain dry for several more years of our ownership. Hats off to SeaRay for addressing a serious problem.

The 370's have a widespread issue of water getting into the forward portlight, and then running under the shelf covering, saturating the bolster around the vee berth, down to the "nightstand" piece, and then in my case behind the cabinetry, and out to the floor under the steps/drawers.
After many years of chasing this down, sealing the portlight with resin, and countless other things, I notice this:
it doesn't leak into the cabin/portlight if my full front canvas covers are up. (Windshield gasket is my #1 suspect).
I believe what is getting saturated, and causing water to come up from the bottom of the portlight is the 1/2" wide hull feature, where there is a lip in the hull and the ports and whatever are mounted within that space. From the outside, its where the hull goes from Arctic White to a light grey. That tells me that this non structural part of the hull is probably wet, and, well you know. Way too rainy right now to even take a reading, but all of my windshield screw cover gaskets are up for replacement, and then I'll leave the cockpit cover off for a dousing, and see if my theory stands.
