EVER WONDERED HOW TO SINK A BOAT?! And then go scuba diving on it?! It's not very often you get to witness a boat sinking beneath the waves. While in Grenada we were lucky enough to, not only see it, but be part of it! We were onboard up to the last few minutes before the Tyrrel Bay went down. She was cleaned and scuttled specifically to become a dive site and artificial reef.
