There are many halibut schooners still fishing the Gulf of Alaska more than 100 years old. Also a few hundred wood tugs on the West Coast. Most as liveaboards, but I know of a couple still working. At least hundreds of commercial fishing boats are wood and going on the ocean every day. My boat is wood 1942, almost all the hull is original. I keep rock salt or borate (a salt) in the bilge.
As long as bottom paint is kept up (no worms), salt water preserves wood. Old wood boats and ships were built with salt boxes along the top of the hull, between the ribs, under the deck. Filled with rock salt, condensation, deck leaks went thru the boxes, preserving the ribs and planking.
Fresh water and rain is the killer. When I sit in fw for extended times I double up the salt in the bilge.
