Author Topic:   Rot...

I have a BW Nauset, not sure of the year, but its pretty old. There are no signs of rot. But I was wondering, what should I do to prevent rot in the future? Also, are there any tell tele signs of rot? Thanks!

Moist wood will tend to swell and could cause gelcoat cracks in extreme situations. Soft spots may also show up as circle shaped cracks. Tap any suspect areas with a plastic ballpine hammer. Soft spots will have a distinctly flat sound. Most likely place for rot to occur is around fasteners, screw holes, bullet holes, etc. . .

In terms of prevention. Make sure your fasteners are properly bedded with a polysulfide caulk such as Boatlife Lifecaulk, or 3M 4200. The problem here is, if it's wet inside, you probably won't get it dry. If it's moist you can try filling with Git Rot and then rebedding after it cures.

becarefull of the Git Rot. Its not determined that this wont eat the foam

ok, I spent a few hours last night going throught the old posts on the repairs section. I was looking at any posts relating to both this topic and also non-skid. I still have two questions:
1. Have we determined if the high temperature reaction of GitRot will absolutely not do damage? Why take the chance with GitRot if one can achieve comparable results at minimum risk with other epoxies like West System? Personally, if someone like doobee, who worked at the original plant, thinks GitRot is ok, I'm inclined to believe him.
2. When people remove part of their floor to look underneath, as some have done here, how do you put the floor back seamlessly? I can't quite picture the process.

Git Rot is a form of epoxy. Epoxy will not react with the foam. It is possible that a large quantity of Git Rot would generate enough heat to melt the foam.
In this application I believe we are talking about screw holes. A few drops of Git Rot in a screw hole will not likely contact the foam, nor will it generate enough heat to do damage. You certainly could use West System in lieu of Git Rot, though I don't think it will penetrate as well. Also there are some combinations of West System that can generate heat. I damn near destroyed the transom of a Non-Whaler last summer using West.
As for removing the floor, I wouldn't start removing the floor until it starts trying to remove itself, causing cracks in the deck. I once saw pictures of a 79, 21 Outrage that looked like a 3D wood location diagram. The wood is there so things can be attached to the deck but it doesn't affect the hull's strength. Truth is, once it starts to rot there is little you can do to stop it. Once you start removing sections of floor, you are taking large chunks out of the unibond, possibly weakening the hull.
whale on!
