Yes and no... From a functionality stand point they are basically sea swirls with a number of enchancements:
1) You can set how much rotation you want
2) You can set speed of rotation
3) They can handle much more flow than the sea-swirls
4) They are much better buil than the sea swirls
I own both 2 wavy seas, and 2 sea swirls, so I feel confident with this reply.
