What a subject

What do you consider "isolated"? Does a rubber hose that connects a thru hull isolate it? If so what's the advantage of bonding or not bonding?

There's so many different opinions on this subject. A surveyor that I know & respect said in Europe it's common practice not to bond any thru hulls because they feel they're "isolated" when connected with a rubber hose. However when there's seawater sloshing around in the bilge the opportunity presents itself to "connect" all underwater thru hulls to the keel which is lead & the disimilar metal issue comes into play.

He also said he's for bonding providing all electrical connections are without corrosion so there's no resistence so everything is equal.

Personally I'm so confused about this subject I'm wondering if there is a right or wrong answer.
I'm not happy unless I'm complaining about something.
I'm having a very good day!
