Zinc Bonding thru hull metals

[curiouskb]

While doing work on the hull bottom of my 3 year old Princess, realised suddenly there is no wire bonding of all the thru hull bronze/alloy seacocks to the zinc anode. Told by local dealer that this is not necessary for Princess boats. This is quite contrary to my idea of preventing galvanic erosion.
Would appreciate opinion from other Princess owners. Thanks.

It is the same on our Broom. Perhaps because seacocks don't have any conductive connection with the rest of the boat?

I like to think that with serious boatbuilders like Princess and Broom they know what they are doing......??

Never heard of any issues with Brooms at least. Be interested in other replies/views.

There is no need for an anode on seacocks as they are not in contact with other metals.
