The Xanadu supplies them for free with their rooms, which to me turned out to be about what they were worth. No negative reflection meant for Xanadu.
The wind continuously blowing from easterly directions at 30 mph gave us much more of a workout than we wanted to endure on vacation and seriously interferred with our rum drinking. One trip out to the reef was enough to convince me. The rest of our reef trips were by motorboat, thank ya.
I assume there are times when the wind doesn't blow, but haven't seen it personally. If so, the kayak would be a great way to snorkle the reefs. You might could paddle out and still have enough energy left to swim.
