Impressive that they can right a capsized kayak, would be nice to have a diagram of forces involved. Angle implies lift, but both lift and area...
Sorry if my presentation is confusing. All prototypes were singular (except 7G which has become my general use pair) and matched with comparison...
Thank you for your response, you may be right, my physical dimensions could be less critical, answer maybe in the dimensionless Reynolds number....
[MEDIA] Boat rows straight with unmatched oars. Clip 1 and 2: 7A starboard oar matched with 7H2 port oar, boat turns to starboard due to poor...
A slow dinghy with oarlocks fixed to gunwales has a different blade motion geometry than a fast racing shell with outriggers, FIG 1, 2. FIG 1...

The above diagrams and text describes the process of reducing blade area and embracing flutter to good performance effect. Vortex induced...
Thanks for your response, sorry for the delay. Figure 3 shows idealized rotating blade maintaining angle of incidence to flow vein for lift but...
The middle third of arc is also the deepest avoiding ventilation of high speed entry. Also, this the area of flow reversal over the blade. and...
Little experience with kayaks but there seems to be much more nuanced control than with oars. Fig 2 dinghy diagram shows little horizontal travel...
Thank you and the Irish, so any stick, even a deer's leg, might do, but why? Foil seems to be high aspect operating at low Reynolds numbers, with...
Way too many suggestions for my limited capacities, but a tennis racket came to hand, lousy oar but good ventilator, "sometimes(not)worthwhile"...
Point was trying to show the geometric difference between two distinct rowing systems. My objective was to satisfy my curiosity, after kayaking...
