Experiences of ESD - Electric Shock Drowning

I made this thread in order to gather experiences and good knowledge from forum users regarding this topic.

What experiences and knowledge do you have about Electrical Shock Drowning? Or in general, the dangerous electrical field created around a vessel in dock, supplied by shore power?

I met many people around marinas that dont know about this. Personally I dont have much knowledge about how easily problems and a dangerous situation occur. Nor any experience of people I know that happen in such situation, fortunately.

I post a link where you can read about this if you dont know what it is:

ESD is almost exclusively a freshwater issue. Very rarely (if ever) occurs in saltwater.

Very interesting article, thank you. We often get boats on the hardstand that have electrical leakage that can be felt at the propshaft or saildrive.

Re: Experiences of ESD - Electric Shock Drowning

2 or more problems Must exist. And it only happens in fresh water.

More common is a lack of ac to dc ground bond. And then ac hot shorting to dc ground. Rubbed wire etc (Which puts 120v straight into water. And breaker will not blow without ac-dc ground bond.

Nobody knows how often it happens . Because the cause of death from Coroner will simply be drowning.

Likly not very often. But does happen.

This is why every marina has a no swimming sign.

Iso transformers and elci’s make the boat much safer.
