The result is greater thrusting power with the same amount of effort. Latest development in channel thrust is the super-channel. The blade is designed with a large flexible central Super-channel propelling water-flow more efficiently down the fin blade instead of letting it spill over the sides for optimal performance and minimal diver effort.
