If a glass bottomed boat's your thing, more power to you.
Thought you should know that this boat goes VERY SLOWLY. putt, putt, putt, putt
If what you want to do is take a ride and see the reef, try the snorkle trip. They'll even give you a life vest if you're not a great swimmer. If you can't swim at all, i guess the glass bottom boat is better than nothing but man that sucker's slow.
