be more efficient when powered by a pulse (paddle) than continuous
(constant pull in tank) force.  so maybe tank tests could be devised to
more closely simulate that?<<<<<<

I'd like to test kayaks with a paddle that can measure the force applied to
it and the angle of the paddle at the time the force is applied because the
paddle force is off center and thus causes the kayak to yaw some back and
forth as it goes through he water (and towing tank tests do not account for
this and it would be very difficult to simulate the correct amount for each
kayak and each speed).
Last February I suggested to Chris Cunningham at Sea Kayaker that he might
be able to put me out of a job (drag prediction) with one of these for a
paddler. Back then weba-sport was advertising one for paddles but I don't
see it now on their website and the old links don't work. I think Chris
inquired about them then and they weren't yet ready. Maybe the company
didn't get much interest and decided not to develop a paddle version or they
are still trying to work out problems and don't have any in production.
