I just read this (weirdly ungrammatical) item and thought I’d rush out today’s invention before some global sports equipment manufacturer can patent it.
If it’s indeed true that splaying fingers and toes allows one to swim significantly faster, then the same can be applied to oars, paddles and maybe even propeller blades.
Today’s invention is therefore a rowing blade that has the same wetted area as usual but which consists of separate ‘fingers.’
