Zincs and Bonding

Post by Quetzalsailor »

You may recall that I posted a question regarding zincs, quantity and bonding of underwater parts. I also googled the question and came up with this site, emailed them and Bob Olsen, sales@BoatZincs.com, 978-841-9978, replied immediately. He calculated the amount of zinc I need for my estimate of square inches of underwater metal, temperature, salinity, and hours in the water. Very helpful!

He feels that restoring the bonding system in my North East 38 is appropriate. Bonding for corrosion protection, not lightning protection.

As you know, bonding is a big can of worms with opinions ranging all over the map!

One big factor to consider is if you keep your boat in a marina with dock power where there may be lots of stray currents in the water, even if your boat is not connected to shore power.
