How would I be able to tell that though? Asking since I have my rudder off right now and fighting to get the barrier coat off before fixing some minor osmosis bubbles.3/4 of all sailboat foam core rudders are wet on the inside
Drill a hole in the bottom & see if any water comes out.How would I be able to tell that though? Asking since I have my rudder off right now and fighting to get the barrier coat off before fixing some minor osmosis bubbles.
And would like to know if there is more to it while I am doing the work anyway...
The surveyor for my last purchase said that virtually all such rudders are wet. I rebuilt my Niagara 35 rudder a number of years ago because I had rusty water oozing out at the top every winter. Turns out the rudder was built with a stainless shaft but carbon steel web (for strength?) inside. Had the web replaced with stainless and filled the core with thickened epoxy. New 5200 around the gap between shaft and glass. Seemed to work pretty well.I'd say 2/3 - 3/4 of all sailboat foam core rudders are wet on the inside. Just a WAG
I think "soggy" is better than "saturated" so I would drill and let excess water out and then seal the hole.
FIFY. A SS post penetrating the envelope will eventually let water in no matter what you do. With a carbon post and good construction you have a pretty good chance of keeping it out. Imagine boring a 3" hole in the bottom of the boat, sticking a SS tube in the hole, and sealing around it with something. Now head offshore, giving the tube some firm twists and yanks every minute or so.I'd say
2/3 - 3/4100% of all sailboat foam core rudders with a SS post are wet on the inside or will be. Just a WAG
