We own a 1979 CD36 (Hull # 8) and where our sole bevels upward just outside the head and into the v-berth we have black stains and occasional weeping of water. This occurs during fine weather and seemingly leads to the assesment of weepage of condensation from the hull where this sole is attached. We want to refinish our sloe but are reluctant to get started before we have this problem understood and hopefully rectified.Any comments or advise is gretly appreciated.

Re: question on condensation at beveled sole CD36
We have a serious problem with this also. Any suggestions re insulation material and sources would be greatly appreciated.Ken Porter wrote: We own a 1979 CD36 (Hull # 8) and where our sole bevels upward just outside the head and into the v-berth we have black stains and occasional weeping of water.

Re: question on condensation at beveled sole CD36
Warren,
My experience comes from my CD33 which I would assume is constructed along the same lines.
I've found that water trickles down from my anchor locker, which at times takes on water from seas through the drain hole or from the anchor hatch.
Have you determined if it's fresh water (condensation) or salt water from a leak? Could also be a leak from your discharge line from your head (again assuming your layout is similiar to mine on the 33).
I've had good luck by putting a small video camera on a pole and pushing it up into that area which isn't accessable on the 33. With this technique I found was getting a small dribble from the anchor locker.
Good Luck,
mike

Re: Ken, be real careful........
Ken,
Be REAL careful when refininshing the sole. It may look like teak & Holy, but it is only a VERY thin veneer over marine plywood. If you sand it even a little, you will break right through it and see the plywood backing. About all you can do to it, is strip it chemically, LIGHTLY sand or rub with steel wool, and refinish. Actually, watch the chemical stripper, it can loosen the veneer from the backing and you will have an even greater problem. Try two part teak cleaner if it is really dirty, and if only slightly dirty, use the single part stuff.
Cape Dory made excellent vessels, but the sole was not included. Two bad it isn't a true teak & holy sole. It would be beautiful.

Re: question on condensation at beveled sole CD36
Ken,
I have a later model (hull number 79), and had only one problem in that area, but the boat came with water stains outside the shower/head. I have a few ideas.
Firstly, you will never get all of the dark stain out of the cabin sole, but you can lighten it quite a bit. Do the chemical bleach thing, but watch out for sanding through the veneer.
My V-berth tank used to leak when filled up. It was a poor sealing job where the tank fill entered the tank. It had one of those un-sealable spiral hoses in there originally. I replaced it and the problem was solved.
There should be a limber hole to let all of the water drain without sitting against wood. I suspect that this limber hole might be plugged up.
I do not have condensation on the inside of my hull (Chesapeake bay) and suspect that if you do not have condensation in other areas of your boat that it is not condensation here. It may be water that has pooled up and does not make it down to the area in question until the boat heels.
Let us know what you find.
