Scuba, Hookah, Brownie Alternatives?

[S/V Aphrodite]

I have read such warnings as well, though I do not recall 'twas in Calder's works or elsewhere. But, I've seen them more than once.


I've only cleaned my bottom in 3 marinas and haven't had any trouble. So far!

Your question is a good one, and I'd like a way to check for stray current before popping in the water too. It would also be good to know in terms of electrolysis risks since I have a steel hull.

Cheers,

Carl
