Monastery can be OK for an OW class on the RIGHT day -- that's rare. The classes you've seen
gearing up may be AOW or Rescue. It's also a good lesson for an OW class -- it's OK to walk away.
We did in my OW class. Best lesson of the two weekends.
The first time you dive Monastery, do it with someone who knows how to read it, and how to get
in and out. Keep your reg in your mouth on entry. Keep your reg in your mouth on exit until you
are 10' into dry sand. Don't stop until you are 10' into dry sand. Crawl on clinched fists, your
head will be an inch or two higher, and it's a LOT easier on the wrists. There's more -- like I
said, do it with some who knows the beach.
Whaler's Cove is anywhere from just out of OW class (though the best stuff is deeper)
to Tech Diver. Bluefish Cove is mostly Intermediate and up, though there's some Beginner
up in the Shallows.
