  For those of you who have used cork as a hull liner, how has it held up? Problems? General comments? Thanks Gordon

A friend used cork lining with sprung wooden battens holding it in
place.
(The cork panels probably glued also.)

He did a very neat job and his boat (not a Vega, a 31-footer) is
noticeably warmer than mine..

Interesting that the cork made the boat's interior warmer. As I'm on the Gulf coast, not so sure that's a good idea. Be that as it may, as an aside, I used indoor/outdoor carpet squares which were fantastic as you could tailor each square as needed (much like cork I would assume). That was 18 years ago and it's still going strong although a bit faded now... It was also very good at reducing interior noise from the exterior sea (which has remained exterior, thankfully!). Hal

This is Ireland where keeping warm is more often an issue than
staying cool. :)

Would cork be more likely to mold due to it being an organic material? I used silver bubble wrap insulation, so far so good, but not pretty.

Cork would have to be sealed on the inside and adhered to the hull perfectly so no moisture can get behind it.

I thought the same thing till I researched it a little. Seems cork
has some natural mold, rot, mildew fighting characteristics to
protect the tree.
Also, that 100 year old wine your butler served you last night was
probably protected by a cork stopper. Wouldn't want an off taste to
your wine, would you?
Actually, cork looks to be a good choice. See

Thanks for that info on cork. I noticed a Tartan 34 with a cork sole. I always thought it felt real nice to walk on. I'm going to look into it and see if I can get some locally.

As a liveaboard, heres my take on living in a cold place.
Outside is very cold. You have say 1/4 inch of wall between you and the cold outside.
Inside is you, making steam in the air. The steam condenses on the cold wall. This collects dirt and can grow mold. In a house, the wall is so thick and well insulated, that the inside wall is not cold and the steam doesnt condense on the wall.

So Im thinking the cork will be very pretty, and may help a few degrees, but wont stop condensation unless you can get the R value way up (R value is a rating system of insulation in houses).

Remember those foam cored sailboats? Etap I think? I bet they would be great cold weather boats.

Totally agree groundhog. Cork is like r-3 per inch. Dow Corning
Foamular (pink foam board) is R-5 per inch and is cheaper. See
How To Insulate a Sailboat – Part 1 : SanJuanSufficiency.com .
As you can tell, I\'m still trying to figure out what I want to do
but it is obvious, anything would be better than nothing (paint,
etc).

Well if there was a way to stop the moisture condensation, it would make life much much better.
Its a constant source of frustration and mold. I guess if you could put some amount of foam behind it? And, foam that doesnt turn into dust with age? lol. It might at least cut down on the condensation which might help.

I don't know weather you said or not but what kind of heat are
you using?

No doubt the heat source has a direct bearing on condensate but
at this point I'm just rebuilding the interior and want to do it
right the first time. If you conquer the condensate problem, you've
basically gotten rid of rot problems and have a toasty boat to boot
(or cooler boat in hot climes). If the humid air in the boat is not
allowed behind the insulation to touch the cold hull and the surface
of the insulation is warm enough to not reach the dew point, then
condensate will not form. Ventilation will also help a lot if you're
doing humidity causing actions (cooking, sex, what have you).
