... respect for sea kayakers, and surfski's.
I got my newly-purchased AI2 on the water for the first time last year in early September - coming from a surfski as my primary on-water vehicle.
Now it is about a year later and I am finally coming to grips with how slow the AI2 is by comparison - and accepting it for what it is.
I have seen the video where Greg Ketterman on a Mirage Drive out-pulls Olympic medalist Greg Barton using a paddle and I believe what I see there.
But that is raw pulling power..... maybe analogous to me on my mountain bike in a 19-inch gear out-pulling some athletic guy on a road bike in a 110-inch gear.
I do not know enough about physics and the ergonomics of paddling/pedaling to explain it.
Flat water, no wind; paddling my surf ski I can catch up with and stay with an extremely-fit, strong, relatively-young guy pedaling a Revo/Mirage Drive.... and I'm older than dirt.
My uneducated guess is that pedaling a Mirage Drive uses fewer and smaller muscles than proper paddling - which uses both the legs and the core muscles of the upper body. ..... After a 1-hour hard workout on my surf ski, my legs are so trashed that I have trouble walking back to my car. ..... Also when paddling and doing intervals, my heart rate quickly rises to over 90% of it's "220-minus-age" max.... whereas I find it quite difficult to get it anywhere near that pedaling my Mirage Drive..... I can do it, but it's not what I would call pleasant.... concentrating all the load on one or two muscles in my legs.
