Wood Boat Maintenance
I am restoring a 1956 38 foot wooden sail boat. I am replacing all the through hull bolts and fasteners. The rusty original through hull bolts are galvanized carriage bolts. The rust has destroyed portions of some of the wood shoulders they seat on. I was thinking of replacing them with silicone bronze. I am getting a lot of different conflicting information on how to proceed.
The surveyor said to replace with what ever was there, but the future rust factor and damage to wood is my concern.
The under water hull has three different kinds of metal on it, galvanized through hull bolt about 75 of them, 130 stainless 2"screws. and 5 Bronze through hull valves. On this I have been informed that all the metal should be the same kind, to prevent relectrolysis between different metal. Makes cense.
Also I have been informed that the wood boats should not be bonded because the wood would will be damaged by electrolysis around the Zinc fitting,
In conclusion my plan is to, remove all fasteners and treat the wood with smiths epoxy, and replace all galvanized and stainless fasteners with silicone bronze.
Dose anyone have advice on weather or weather not to replace rusty galvanized bolts with bronze bolts in a wood yaught.
