Freedom of the Seas gets the flow

OK this is bizarre, the world's largest cruise vessel, Freedom of the Seas, coming in at 160,000 tons and more than a fifth of a mile long, is going to have a FlowRider on it, simulating a 10-foot-high ocean wave moving at 20 mph; so you can go for a cruise and surf on deck miles from shore? Now maybe I'm missing something, but how many surfers do you know who are likely to go on a cruise ship? It's near zero as far as I can figure, and can you get a zimmer frame on a surfboard for the blue rinse brigade?
