Interesting, I'll have to see if I can locate this.
Another question about the bilge area. When the carpet was replaced the mechanic cut a small hole to look at the stringer and repaired. He said the stringer looked pretty good, some moisture (it had just rained uncovered), but things seemed sound. Is it ever advisable to put some antifreeze or anything like that in the bilge area as a precaution for wood rot?
