I'm just guessing that dolphins probably wouldn't care for the noise associated with the personal watercraft necessary for the game.
Zodiac boats, jet skis, all the other crap. It's whale season for me and it bothers me when I see those who cater to tourists chasing and obviously disturbing whales.
Call it cool, but there are other lifeforms on the planet that undoubtedly find the human noises really offensive. Enjoy the environment, but it doesn't take that much to respect it while you enjoy.
