Pedal powered sailing tools are nothing new. Here's a photo of an on-deck blender.



The latest human powered airplanes (and blenders) are using a rowing machine style of human power, giving up on the bicycle style. Something about using only the big muscle groups.

If they got really strong at that technique a grinder/rower wouldn't ever run across the tramp, they'd simply take the whole width in single power jump, like a frog. Just don't overshoot.

I'll get my coat.
