Re: Dry My Hull
Common salt is hard on plain iron fasteners, but less destructive to the hull than dry rot. Most all other presevatives that I am familiar with are corrosive also. I know of many boats that were put together with common boat nails and after fifty years of salt used as a preservative, they are still sound.
Galvanized fasteners, silicon bronze or stainless steel fasteners are better of course. There are just over 11,600 SS ring shank nails in my launch hull, but who is counting? I never wanted to refasten the planks and the nails have shown no corrosion at all. The hanger bolts that hold down part of the propulsion gear are common steel. There is some corrosion on these, but not even close enough to worry after 8 years.
Remember that if you keep the wood dry, the corrosion will be kept at a snails pace.
