Many great examples, including the Brothers of course! But the Dutch stroke in the last video is perhaps the most remarkable: relaxed-looking, almost smiling, during the recovery -- even in the last stages of a race, at 36 spm or more; no unneded tension, no waste of energy. Catch-accelerate-relax-let run. So good.
'See how the blades sky before the catch, because the co-efficiency of the hull doesn't accommodate the asymmetric profile dimensions...... Stroke is flawed...... Blades have been failing for 35 years.........Square look?'
