Dan,

  Odds are that any bare wood in the chain locker area will have at least some moisture in it which makes oil based coatings problematic.  If your desire is to try and prevent the wood from rotting a good choice might be a Borate based solution such as Timbor.  Timbor comes in a powder form which you mix with plain water, it has low toxicity to humans and almost no odour.  It also kills bugs albeit slowly.   There is another mixture that uses ethelyne glycol and Borate which is more effective but I don't like the smell of glycol and it is quite poisonous to humans and pets.  Linseed oil will turn black quickly in such a humid environment and I have serious doubts about it being a preservative.  Some of the older copper based preservatives were reasonably effective for a surface treatment but the penetration is poor.  The Borate on the other hand will over time will work it's way completely through the wood.   The best place to apply the solution is to the edge end grain of the plywood if you can get in there with a spray bottle or something.

  If you can find a way to keep the humidity down in the locker, it will certainly extend the life of the plywood with or without a treatment.

Best,

Has anyone used linseed oil or other wood preservative to treat their exposed wood above the chain locker?  


I inspected my wood on BeBe, SM387, before leaving for the summer and have it on my list to apply something protective when I return.

Bill, I had the same problem a few years ago. I cut the floors out leaving about an inch of tabbing all the way around. Then cut another piece of plywood to fit , resting on the tabbing. I epoxied the bottom of the plywood first , then installed it and glassed it into place . I glassed the entire surface , rather than simply painting it. It was nice meeting you in Annapolis.

The plywood soles of Harmonie's bow lockers are seriously rotten.  I was kind of surprised to see that the bottoms of these plywood sheets (i.e., the top of the chain locker) were "naked", without fiberglass sheathing.  I suspect exposure to the constant damp of the chain locker for 20 years was the start of the problem.

Replacement seems to be a fairly straight forward, fiberglass project, but if anyone else has had this problem and has any hints or "gothcha's" to watch for, I'd love to hear them!
