most fasteners in saline environments fail due to electrolysis (unlike metals in a electrolytic media) ... one of the first things I look for, during inspections, is fasteners that are mixed ...ie bronze and galvi... the futher apart the metals are on the galvanic scale or chart the faster they will be used up
I have one wooden vessel that has been in service (read annual coast guard inspection) for 50 plus years --- still passes coast guard inspection every year - spruce with galvi fasteners --
has anyone tried "antifouling " paint on exposed timber in termite zones 1 and 2 - grin?
the current stuff has about 50% ( down from 80 or 90 percent in the day) copper by weight - about a 100$ per gallon less in bulk
in closing I still believe ventilation and regular monitoring are your best defense.. I have used co2 to get termites in sensitive locations on boats - just freeze the little buggers ... no toxins required ... first you got to find them... and its best to treat them before they spread
