The blue ooze
I have a cd typhoon sr, hull #50, 1987. Last year when I hauled out I discovered the blue ooze on the outside of the hull and below the water-line. Now the blue ooze is oozing from the inside of the hull in cabin and cockpit lockers.
Open to your experience in dealing with this problem. Are the inside oozings any different than the ones on the outside?

Re: The blue ooze
When we had our (former) CD 28 #383(1985) surveyed prior to purchase, a similar oozing was on the bottom. I contacted a former Cape Dory dealer in my home area who said while not normal, he had seen it before and I shouldn't worry about it. The surveyor speculated it was a dye added to assure more consistent layup, or the result of a chemical reaction within the hull due to moisture (salt water) reacting witht the resin. We bought it, let it dry for several days, and took our chances. After 2-1/2 years, no problems. However, we never saw it inside the boat.Donald G Hill wrote: I have a cd typhoon sr, hull #50, 1987.

If you can reach someone, I'd recommend talking to a dealer or someone at Robinhood Marine.

Re: The blue ooze
Donald, We purchased a 1984CD330 last summer with "blue-ooze". The former owners had gone through extensive tests & stripped the bottom to isolate the problem. In a nutshell, the ooze is caused by a blue-tinted layer of epoxy sprayed onto the solid fiberglass hull during manufacture. The blue coloring makes it easy to see any thin spots during the following gel-coat spray. After many years,seawater permiated through the gelcoat & acted with the epoxy layer that for some reason did_not_cure properly. Our boat had no moisture in the fiberglass itself. Nick at Fort Rachael in Mystic Ct.(excellent fiberglass shop) redid the epoxy barrier coat & gelcoat. Your problem may be more acute if this blue layer is leaching through the solid layers of fiberglass into your hold. Have you had a moisture meter test?

Re: The blue ooze
my surveyor told me that builders in the north would add cobalt to the epoxy mix to help if cure better in colder weather. who knows?

Re: The blue ooze
When I performed the blister repair job on my CD26 (see my 1-17-99 posting) I saw hundreds of areas on the hull where 'blue juice' appeared as I ground away the gelcoat beneath the water line. I am not a chemist but the research I did at the time told me this was cobalt. As I understand it, cobalt is used in all polyester resin and is not unique to the cold weather use of the product. If blue ooze is present on a CD hull I am sure blistering is present as well. Also, epoxy resin is not used in the layup of production fiberglass boats, at least not the vintage we are talking about here.

Darn! I was off the BBS moving about while this subject came up. It's one of my pet peeves that nobody could help me with when I tried to find the source of the blue ooze you describe on the our CD25D before we bought her. I could find no structural problem at all because of the ooze (which disappears for a while when washed with bleach) and our surveyor tried in vain to figure it out, an engineer who worked for the factory when the boat was built had no real answer, Dana had a thought about "blister water" and I've heard the story about cobalt. We bought the boat(the last 25D built) anyway and figured we wait until Sigourney Weaver or some other alien popped out of the hanging locker. I know we have no blisters or water penetration in the areas the ooze exists, and we do have some wet spots on the deck with no ooze so I'm not convinced the ooze is related to water in the hull.
Or anything else important.

Don: Re your posting of today on this blue ooooze thing, I had to put my CD-33 in the water yesterday, with the darn thing oozing from both the rudder and in some areas on the keel. i have read all the correspondence on this subject in the Web site, and now I don't know what to think. if you find out more about it, please post it for the benefit of us all. thanks.

Re: The blue ooze
The guys at Robinhood denied any knowledge as did a fellow worked for the factory in '89 and a saleman who worked as a rep for the factory back then.The only thing I didn't try before I just gave up, was to send a sample to a lab for testing. I only have a little showing where the cabin liner has been hit or otherwise worn, like under the stair rail.
Cleaning those parts with bleach from time to time is not a problem. There is quite a bit showing on the inside of the hull, like in the anchor locker but that doesn't show. I've decided it's nothing more than a cosmetic problem and sail happily along. I'll be sure to post an answer or a picture of the alien peering out of the hanging locker --whichever comes first.

Re: The blue ooze
Zeida-- My blue ooze is definitely not--NOT-- oily or resin-like. It's dry and creeps along cracks -- the very fine invisible ones caused when the hull-liner was put in place -- and other mars on the hull liner. I though at first it was some kind of mold. The oily, wet kind, according to Dana, is likely to be "blister water". I'd e-mail him for more info. Arenius@jlab.org
