Hi all,
I have some water leaks, traces of water, streaming down, from what appears to be where the deck mounts to the hull,
more noticeable where the tracks for the cars are mounted port and starboard sides, makes a ugly brown mark every time it rains, coming down the inside cabin,
you can see a seam where they mounted the deck to the hull, I have a 78
any input on this , regarding sealing etc, would appreciate it,
thanks

I eliminated most of that by removing some bolts from the tracks, squirting some silicone into the holes, and rebolting. It's a messy two-person job--one in the cabin to replace and hold the nuts and get covered with silicone--the nuts are behind the teak trim strips that are screwed to the top of the hull liner.

Another possible cuplrit is the rub-rail, although I think a leak there will go to the bilge and not to the inside of the hull liner.

I believe that if you own a C25 you live with leaks around fittings and windows, etc. Follow David's recommendation and then repeat as it will need to be done periodically. The key thing is to make sure that the integrity of the deck/hull remain intact and that any leakage does not cause more significant damage.

The "ugly brown mark" is either residue from the plywood or oil from the teak trim the water is seeping down behind. I suspect there's enough structural strength at the side-decks that some deterioration in the plywood there isn't going to be a big problem--it's that ugly brown stuff... But hey, she's thirty! Any teenager will tell you that's REALLY OLD!

I believe that if your boat has leaks they need to be fixed.
My 27 year old has no leaks. My bilge is dry, and generally only gets wet when I spill beer.
The only area where water comes in on my boat consistently is where the pop top meets the hatch boards. Its a situation I'm going to address this spring.

How do you plan to fix the water that is coming on from the gap between the pop top and the hatch boards?

I have the exact same issue with my 78 catalina 25.

Thanks

I thought I had that issue, but a velcroed vinyl cover over the vent slots on the top board solved the wet quarter berth for me.

I don't know yet.
PO screwed a piece of canvas across the top of the sliding cover on the pop-top, which effectively keeps the weather out. But, its ugly. So, I will probably affix good weather strip to the leading edge of the sliding cover - and if it doesn't look good and work - I will look for a better fix - which might mean replacing the hatch boards.
This isn't a big problem relative to water. The only time water gets in is when its raining sideways. Usually I put up a boom tent or a pop top canvas when at anchor or on the mooring ball. This is a bigger problem relative to mosquitos. There is a gap between the top corners of the hatch boards and the slider just big enough for Skeeters. There are few annoyances worse than a mosquito buzzing you in the middle of the night.

Thanx for the pix Frank. I was looking on your site last night looking but didn't see these.

The Teak part with the handle, affixed to the slider is what I consider to be the problem on my boat. I will probably replace mine - but first I'll try to repair it. Mine looks like the PO attempted a fix for the gap but blundered by using a strip of canvas. Now I've got screw holes to deal with.
I'll refinish it and try a good quality rubber coated, door weather stripping.
If I eventually have to replace hatch boards, I'll go with plexiglass swinging doors that I saw advertised in Mainsheet.
