Hello, I am looking for a freediving monofin or at least something that would be good or just ok even, in open water that is close to the shape of a whale tail. I have a picture attached of what I have in mind, but the fin in the picture itself is not suitable for open water. Does anybody know a fin out there that is good enough for open water and is at least relatively close to the shape of the fin in the picture? Thank you for your time and for reading this.
