third party electrolysis ?

Hi All, has anybody suffered damage to props/anodes/sail-drives  from a faulty vessel berthed adjacent to them, and if so was a third party claim successful? proving it could be difficult i think.

Electrolysis relies on a complete circuit so 'you' must be contributing to the problem. If nothing else, I would recommend galvanic isolation to protect yourself from any neighbour (and that includes the metal pontoon structure) that you may be sharing an 'earth' with.

thanks "Dawntrader" can an adjacent vessel omitted DC into the marina? With no shore power connected?   would the batteries need to be wired incorrectly to earth?

You would need to be electrically connected to the other [vessel/pontoon] for it to affect you. This is usually caused by sharing a common earth - eg the shore power cable. If you are not connected to the other [vessel/pontoon] this way or by any other physical connection then electrolysis cannot occur between you. A galvanic isolator provides this 'dis-connection' and protects you even when connected to shore power.
Why do you suspect this other vessel?
