Modern blade shapes may not be the best fit for the use and geometry of a dinghy. The 3 blades in video vary greatly in area and aspect ratio yet perform equally well. If such a large area reduction were applied to a modern blade, I assume performance would suffer? I am quite the amateur here, no id...

I admit to having a poor yachting image and rowing technique, I am a sailor who rows to sail but sometimes the means to an end becomes a distraction. Question is: why such a large difference in blade area has so little effect on performance, it seems impossible to row straight with such an imbalance...

Clear and concise explanation of rowing, though not entirely applicable to dinghy rowing. In "Pursuing the not so ideal no blade" surface area - substantially decreased, should result in large slippage. Intuitively I should be rowing in a circle with these miss-matched oars? tip shape - if blade enc...

The bladeless oar seems to require less force, maybe due to more slippage, and does its sweep in slightly less time. I understand the subconscious corrections of a long time rower and was expecting an unequal input that never materialized Lots of good research https://eodg.atm.ox.ac.uk/user/dudhia/r...

I have tried these thin blades on a kayak. It was slow on startup and turning to a stop, but once boat is in motion all 3 blades pictured have equal performance(+ or - 1 second in a 30 second run). If lift, drag or some combination of the 2 is involved, blade area should count? The Greenland paddle ...

I'm so sorry! But I tried the link, from the post, and it gave me the video. Maybe refresh the page? Here is the link, again: https://vimeo.com/1057557722 Thanks for trying --

vimeo link should work now

Electrons always way ahead of me, will try to fix this.

Maybe not for recreational rowing in a small dinghy. The three oars shown at start of video can be miss-matched as a pair and in my many tries the dinghy rowed straight indicating some parity. Why would such a reduction in blade area not be evident in performance?
