Solid glass hull sweating...hull liner carpet?

[Helen L]

So I've ripped out the bunks down below and everything else. This winter I'm rebuilding them all but also was wanting to fight the problem I have with the hull sweating down there. When its cold out everything gets damp and the hull is always wet. Has anyone used marine grade carpet to fight this? I have a bus heater ill be ducting down there which will hopefully help.

Sidepoint, but if the hull was cored above the waterline, that prevents that here doesnt it? I'd worry with just carpeting there that might be a condensation issue there and leading to mold other crap in a sense... I'll be watching this one to see what the experts say...

 

[Helen L]

thought about the mold. theres already mold i had to remove from down there. the carpet liners ive looked at say mold resistant. not sure if that helps. i believe a cored hull doesnt have this problem (as much) since the core acts as insulation. im solid all the way up

Gluing carpet directly onto a solid hull will not achieve what you are looking for. The carpet will absorb the moisture and hold it longer. You will be back to square one with a moldy mess to deal with. I have a sold hull in my JC. In the cuddy area I had them install a cabin liner of molded glass. It gave a great finished look and no wetness in the cabin. I liner is not a option for you. However you can do something a little trick that will work. I would glass strips of 2” by 1” furring strips of wood to the hull. Next I would get sheets of plastic shower liners sold at Homedepot. They are cheap & come in 1/8" thick 8' X 4' sheets. I would cut the sheets to fit and then screw them into the furring sheets with screws & finishing washers. We did some headliners that way and it came out great. Plus it is easy to clean. All trim edges can then be capped using the same material. The hull will still sweat but it will not sweat on the plastic sheets.

Interesting idea. Well, you've sold me on scratching the whole carpet thing. Figured it was too easy anyways. Not sure about lining the hull with shower curtains though. Feel like it would rip at some point, plus one of the bunks is also used as a makeshift couch, using the hull to rest your back on. You gave me another idea though. The hull has foam cored ribs glassed in throughout. In the cabin they line the hull every 1.5' or so all the way up to the trunk. What I could do is sheath the inner hull using the ribs as spacers, then carpet the sheathing for a finished look.

ribs

 

[captainlarry84]

You will not rip this stuff. It is hard flexible plastic type material with a pretty textured finish. It is like working with paneling only it is plastic. Cuts easy looks pretty and not expensive.

$26.00 for an 8 X 4 Sheet great stuff

Anyway to use some spray foam and then put some sort of fabricated panel or other material over it?

 

[Helen L]

hahah, oops! I was thinking you were talking about shower CURTAIN liner. I was having trouble seeing how that would work but ya something like FRP was what I was thinking. thanks larry

 

[Helen L]

I was thinking about 1" foam just using foam board adhesive to line the hull, then sheath with FRP or something similar utilizing the ribs as stripping.

Fishing this November was tough sometimes. 30* at night at times, bus heater disconnected by previous owner, only using the engine room heat itself to heat the house and cabin. Next year I'd like to keep the warmth in better with the bus heater connected.

The key to prevent the moisture in the cabin is the Furring strips which allows a small layer of air between the hull and the liner material. Anything put directly on to the hull will sweat. Your hull is plenty thick. The furring strips could be tacked into place by using a few very short screw so the strips bend to the hull contour. You could even rip a sheet of 1/2 plywood for the furring strips. Once tacked in place one lay of glass and your base is done for the paneling.

 

[Helen L]

I hear you, the ribs glassed into the hull are about 2"x2" and could serve as the base for paneling leaving a 2" gap or 1" if I were to insulate with 1" foam board. Insulating would only serve for keeping heat in not stopping sweat.

 

[captainlarry84]

If you have ribs already then 1/2 the work is done. You may need to add a few however in edge areas. Once it is up even if you did not get a pefect fit. The edges can be trimmed with Plastic molding and a little silcone around the boarder. There is no end to the trim you can use and the selction is big at Homedepot and cheap. Made these kick panel liners on my JC with that stuff and trimed the edges. Great fit and easy to do.

I do carpentry work in the winter. Lot of trim in the wood shed right now. Still have to finish all the trim in the wheel house and do the headliner too.

I took a good little dipper tonight with this... Right now my bilges in the engine room have no horizontal surfaces in them, its just the curve of the bilge. So I push myself through here and whoosh, went right in! I see a project of putting in a platform... FUN with no traction...

Tim,i used carpet tiles down forward...i glued them with liquid nail...i have had them on there for 12 years ...no mildew....as Travis sez...easy peasy....i will post some pictures of them for you tomorrow

I have a plastic grate that lays on part of the I beam for the engine mounts and a stringer that gives me something to stand on in the engine room. My bilge is like thunderdome....2 tools enter one tool leave

I'd really like to see a pic thanks

Platforms are easy, tongue and groove those suckers. You can snap them together to get the exact size platform you want, and if need be you can take some out to get access to things.

Sorry about the messy picture, I had meant to pick that soda can up off the deck...

I laughed walking into Harbor Freight today getting some junk tools for the boat today, knowing they wouldn't make it the season, in response to your thunderdome comment...

 

[Helen L]

its ridiculous, I lost a variety in the bilge during the refit. not worth sifting through and oily watered bilge for a wrench that you cant even reach.
