Forward hatch drains

   another (accidental) reflection. falling asleep on the  deck  while at a buoy, I realised that the seats on the deck have a slope going down towards the stern. the same is true for the floor below the two tables, and for the tables too. is it the original design intent , or another confirmation we have the wrong "trim"?

	The cockpit seems to drain well enough. No trim issues there. My only complaint is that the cockpit drains under the table empty into the dinghy below if you don't spend a lot of time with the black strip that apparently is intended to steer the water to the sides. In any event, I always have to leave the plug out in the dinghy so water does not collect.

	I agree , I don't mind the trim here. I simply thought that the overall boat seems to have a consistent trim that's not the intended one ...it could be configuration dependent: I have the t-top and the short keel...

	Its compounded if you mount something like an outboard on the stern rail, or store spare diesel / gas jugs in the dinghy hanger. I've tried to counter this by putting cases of bottled water, 4 bicycles, a spinaker, and lots of other stuff in the bow locker, but its not enough. I've often thought of putting some old batteries up there, but the trim issue is not a big enough problem.

	I have the same problem, the forward hatch ( sail locker ) is marginally higher than the hatch in the cabin, so the water runs back, sits in the channel round the forward cabin hatch, thank leaks into the cabin. Im told I need to replace the seals, which is likely, but any other solutions before I do that?

	Just make sure the channels are as clear as possible so that it EVENTUALLY runs out. Beyond that, see the prior comments about adjusting trim by putting extra ballast forward.

	If the problem comes from lack of drainage forward, whether through blocked drain channel or weight bias that raises the bow, it would seem that replacing the seal that sits on top of the hatch frame isn't the problem. Do we agree? I also have this problem: lack of consistent drainage which produces an occasional (not always) leak in the corner of frame of the forward-most hatch. I first thought it might be a leak from one of the screws. So I pulled all those, put a little bit of 3M 4200 in the holes, and then put the screws back in. Didn't seem to be it, so perhaps a compromise of the bead of sealant that was put down on hatch installation? A marina friend pointed me to Captain Tolley's, which appears to be a low-viscosity penetrating sealant. Anyone try this? Or is the only real solution pulling the hatch & re-bedding it? If so, what's the level of effort?

	I rebedded the hatch. to tell the truth , less difficult than what I had thought . now it's perfectly waterproof. I wish that the hatch aluminum would not have started oxidizing below the paint , it may be difficult to replace it now ! Edited by Pzucchel - 10 August 2025 at 14:49

	I'm not sure this is relevant to the leaky hatch question, but in fiddling with my hatches, over several years, chasing intermittent leaks, I made an interesting discovery: if I close any of the salon or forward cabin hatches with the black 'stays' tightened, I'm probably going to get a leak. The tighter the black stays, the more likely I'm going to see drips. If the black stays (which hold the hatch up- not sure what these are called) are fully loosened, I seem to get a better seal, and perhaps less stress around screw holes that otherwise might be leaky, and no leaks. My 505 has channels that drain well. I have some peeling paint on the aluminum frames, but this doesn't seem to matter vis a vis leaks. And some cracked plastic trim on the insides - common issues to many of our boats. But also not related to leaks. Aside from making sure the gaskets are in good shape and seated properly, and all the nuts and screws are snug, closing the windows with no stress on the supports seems to be the answer to leak free hatches. Not sure exactly how this all works together but it seems to be the answer for my boat. Anyone else notice this? Edited by kipwrite - 11 August 2025 at 01:12

	Kipwrite, Never thought of that. I think I will adopt that theory. I definitely haven’t always loosened the supports in the last and I have had leaky salon hatches. Good advice. Thanks. As far as rebedding the hatches, it’s not technically difficult but it is tedious. I’ve done two. There’s scraping, sanding caulking, etc. The paint was peeling in the frames too. I used butyl tape to seal - less messy than caulk. So far, so good. The main problem seems to be the drainage. The seals seem to work fine if there isn’t a constant pool of water sitting in the channels. My galley and aft head hatches have channels with no drainage. Water sits in there all of the time. They don’t leak though, possibly because they don’t have the struts supports to fight against the tight seal? Edited by 32mike - 11 August 2025 at 13:50
