Perhaps it is a good time to try an experiment, by soaking a couple of pieces of spruce in strong salt brine , drying it out, then gluing it, to see if the salt affects the strength of the glue line? Any thoughts from the wood experts?
Brent, as you'd know, as well as being a bit alkaline, salt attracts moisture and essentially stays permanently damp - not a problem in a wet bilge, but a big problem in the base of a vertical structure constantly exposed to the heat of the sun.
FWIW, I'm fairly sure salt would affect the adhesion of whatever glue you chose to use (chemically) a lot more than simply soaking the timber in a patent rot preventative and gluing up as normal.
