Ahh yes. I got a little close to the mangroves and the engine stalled on me with some seaweed. We were only delayed for a couple minutes but Mrs. O. shot me her dagger eyes and I was nearly toast.
They did have restrictions on where you could go, but I don't recall them -- we knew we just wanted to stay inside the reef wall and hang in the beautiful blue water on the south end of the island where you can jump off and be up to your waist in crystal clear water. That's obviously allowed
Thanks for the link -- $110!!??? LOL -- we didn't pay nearly that much. The website says not to ask them to lower their rate. Uh, okay I guess. I didn't need to, they quoted $110 and we walked away. They stopped us and we haggled from there. I haggled a 90-minute rate far less than the posted 60-minute rate. Can't remember the $ total, but I do remember talking them down at least $30.
The website says new management took over in 2007. You might not have the same luck I did. Worth it just the same though.
have fun!
