If a boat is not connected to mains earth (either because there is no shore line or because there is a form of galvanic isolation) then these potentially damaging currents cannot flow. If a boat is in a marina among other boats with "unprotected" shore lines then I understand that it could suffer, but in your situation, where no boat has a shore line, then you should be all right as there should be no "galvanic" currents flowing through the water.<br /><br />This is how I understand things, but I would like confirmation from others!Halfiehttps://www.blogger.com/profile/00167481543065324357noreply@blogger.comtag:blogger.com,1999:blog-701428736862216823.post-35789171745984500372016-11-14T20:51:55.311+00:002016-11-14T20:51:55.311+00:00Big Clive explains what the galvanic isolator is a...Big Clive explains what the galvanic isolator is all about. https://youtu.be/EjQb26juVYo<br /><br />Ralph Shephardhttps://www.blogger.com/profile/03625632894696954780noreply@blogger.com
