There are so many boat renters in those beautiful anchorages craping that I'm afraid to go in the water.

Sorry,,, you're wrong on this one. Granted an anchorage with 2 or 3 boats in it gets flushed naturally but not when you have 30 - 40' Benateau's with 4 to 6 people on each of them craping, peeing, taking a shower and flushing the morning dishes.

It's disgusting.

I can't bring myself to go in the water.
