Satellite Technology is a Wonderful Thing!

I am writing this seated on a boat on the Great Barrier Reef. We are steaming south past Cooktown from a position at 14 39' 47.9" S; 145 39' 50.2" where we had some spectacular diving in perfect conditions (we were also out last week on a lower priced trip and the weather was rather more unsettled... though the diving was still good).
