I know they checked us when we first moved into the marina and found our electrical system OK. I will ask the manager if they can check it. I suspect they might. They have a security guard that walks the docks on a regular basis. Unusual in this region but maybe because it is operated by the Port maybe they are also proactive on the leakage current issue. No doubt the cold water helps and since we are at the extreme south end of Puget Sound the water is lower salinity. No barnacles to speak of, lots of mussels and the Moon Jellyfish seem to love it here.
