Glenn A. Thanks so much for you well informed info. on dumping tanks. I have been slammed for this comment before but I have to say it again. The BVI and outlying neighbors have one of the biggest if not the biggest concentration of sailboats in the world. I have been visiting all over the area since the early 70's and have noticed the steady decline of coral and fish. No I am not an expert and have no knowledge to connect the killing of coral (and decline of fish) to dumping holding tanks but I am amazed in this age of being more earth friendly that it is even allowed. The charter companies and private owners hould be pushing for or providing facilities to handle their boats. It doesn't take a rocket scientist to figure out where all that nitrogen is coming from. It's certainly not coming from farmers fertilizer application!
