My boat ( 40ft Challanger) has a deck
and the deck
is balsa core
is getting replaced and the mast
is removed. I found some rot
under the mast foot. After further investigation I found that the junction box in front of the mast has let water
in the core
The damaged part is about 12 inch by 8 inch. My thought was to dig out the rotten balsa and replace it with a solid piece of hardwood glassed in with polyester resin. I left the inner glass layers in tact .I am getting rid of the junction box and make sure the whole repair is waterproof. Would it be better to build up with glass to make it more solid for the mast foot or is the hardwood block a good way to go?
Should it have had the balsa core under the mast foot in the first place?
I would think that something more solid would have be a better way to go when the boat was build.
