ah, Moosa, the aggressive morays, the currents, the lack of hooks. All sounds familiar. He did good briefings but they always included a disclaimer that the current might be doing something else, and often it was, and sometimes it was a little nuts what we dove in. I could never figure out if it was him or the nature of the area, or a little of each. We definitely did lots of dives that would have benefited from a reef hook and I'd have brought one if I'd known. (He didn't have one at the time either.) I don't recall that he specifically told people to hang onto live coral or what he said exactly, but there was generally enough dead coral to hang onto and of course that's what people tried to do. Tricky, as there was something living almost everyplace and I quickly learned to watch out for those eels. I've never seen such freaking aggressive eels.
