The waverunner depends on how windy it is. We did it on Bora Bora and found ourselves driving blind around 1/2 of the island because of high winds and ocean. We weren't in danger at all but didn't see the back side of the island. It was a great idea but would have, in retrospect, been better in Mo'orea when the weather was a little better. Marc may chime in on this one as he & Arlene went on the same day we did. Cheers, Anne
