I'm glad you tried.
It sometimes helps if you write something (example "Is standing on and killing coral giving you a good feeling?") on a slate and show it to each and every diver that is standing on the coral.
If they were arabs, can they read and understand English???
But that aside What about dive boats (and other boats) that drop anchor into Coral. I have seen this a number of times in Thailand and nobody seems to care.
