I was chatting to Andrew (the boatbuilder commissioned to create the new bowsprit for Ubique) the other day and the topic of electrolysis came up. My dad and I (hey Pops!) have spent quite a bit of time chatting about this, and we have both read quite a bit relating to wooden boats and electroysis.
The consensus appears to be there is no consensus, and interestingly, Andrew said to stay away from any zinc attached to our wooden BCC, as this would exacerbate the problem. He described metal parts suffering from electrolysis as appearing white and fluffy.
I would be very interested in hearing the BCC Community's opinion on this one in this Forum post.
