This '79 Hunter I just bought has a big metal water tank in the bow.
This boat has sat unused for a few years, I understand. My buddy told me
I should by no means drink the water out of it, and should somehow clean
the tank, etc. I've drained the tank and refilled it. I was thinking I
should dump some swimming pool chlorine in it and let it set for a few
days. Bad idea? How should I clean it?

Thanks,

Stephen
