There is a very unique dive fin that I have used for years called a Force Fin. Most folks thought they were terrible or stupid since they are 1/3 the length of many fins, flexible and have absolutely no macho points (Very important consideration for many divers). You can see these fins on the Navy SEALs TV commercial as they jump out of a plane with their SCUBA gear on. They work by creating a vortex as they snap back to their original shape ---------------------- Hi Bob, Would you, or anyone interested, elaborate a little bit on part about votex and thrust generated.
