This looks like a bunch of fun. Boy I wish I was near water like that. I guess Subwing might be name of the brand that makes these fin/wing-what-ever devices. So I just called this post 'Subwinging' because I didn't know what else to call it at the moment. I have never heard of this newer sport yet until I came across it recently. Stuff like this must be a lot of fun.
Enjoy.
