Best way to increase boat speed during the recovery

[@DarkHorseRowing]

🎉 Great explanation

[@InFin8RowingIntl]

Wow. Endorsement from a big name. Thanks

Hi ! It’s so good hearing this! Believe it or not this is the way I was taught to row back in the 60’s😂 I went on to coach my crews this technique in Denmark with the lightweights and to this day I’m still coaching this way! It’s just so nice hearing it from someone else!! Cheers!

Thanks John, and welcome to the tribe. Great to hear it was taught somewhere.@@johnfaulkner1156

This is better than a lot of the nonsense about “checks the boat”, but it does talk about “boat speed” rather then the speed of the centre of mass of the boat plus rower. Newtons first law - Every body continues in a state of rest or uniform motion in a straight line unless acted upon by an EXTERNAL force. There are 2 external forces. One is friction, and the other is from driving the oar through the water. You can accelerate the hull toward you during the recovery by pulling with your feet, but that is applying an INTERNAL to the boat force. Yes the boat accelerates, and you (your body) decelerates a bit and the centre of gravity of you plus the boat smoothly decelerates under the one active EXTERNAL force - friction. At least you are a step ahead of the silly “checks the boat “ stuff when you plant your feet as that is also an INTERNAL force.

Thanks for the comment. And I do agree with the science btw. I appreciate that if you isolate the system of boat and rower alone, there is no net gain in speed, but if you look at my graphic and listen to my conclusion at the end, you will see that the gain I am referring to comes mainly from maintaining boat speed through the recovery and how that relates to resistance. The boat wants to progressively decelerate, and if it does so it sinks deeper and compounds the deceleration due to a larger wetted area. Using your centre of mass to progressively accelerate the boat, helps counter this. As long as you nail the placement and have connected before you drive, you are picking up a moving boat.

Great explanation of an important concept.

Fluidesign uses that weave

Spot on! Absolutely stunning looking boats, and a lovely row too. I competed in one for World Masters 2022, Libourne, and Henley Masters last year.

I like the overall idea of keeping the boat speed constant (to minimise drag) by accelerating the recovery (a little), but I think you are slightly mistaken about the check. Ignoring drag, any change in momentum of the rower must be matched by an equal change in momentum of the boat. This is why accelerating the recovery will accelerate the boat, as you say. But when you inevitably decelerate as you come up to the catch, the boat will also decelarate, for the same reason. By the time you come to place and drive, you have already changed your velocity, and therefore so too has the boat. If you would measure the boat speed in your "no check" sequence, you would find the boat decelerate before the drive, not at the drive. It doesn't change your conclusion to keep the boat speed constant though :)

[@InFin8RowingIntl]

Thanks Mike. I often talk about the system of boat and rower, and yes, I agree that if you ignore the drag, there is nothing that can prevent a deceleration of the system, but drag is a considerable factor affecting the run. Gradually increasing the boat speed (not system speed) during the time that the system is equally gradually slowing down, serves to counter this. Nothing is perfect but we believe this is the best way to make this part of the stroke more efficient. My demo of the fact that the draw does not check the boat is imperfect. I am far from a perfect rower. What I hope comes across is that there is no characteristic check hallmarks, like a bounce on the stern or the boat moving backwards in relation to the direction of travel, as a result of "landing" on the footplate. Deceleration before the drive is unavoidable, but limitable. With the reduced drag from the draw as well as the fact that you get through this part of the recovery quicker, which causes you to spend less time trimming stern down, contributes to overall speed. You have to land the placement though of course.

[@Dirtandoars]

Very clear explanation. Thanks. Mike Purcer in Canada has been doing research in this area as well.

[@InFin8RowingIntl]

Hi and thanks for the comment. I have checked out Mikes youtube vids and I really like the detail he goes into with his analysis.

[@SomersetCRC]

Love it! Thank you for this video so much! little question- how can we get/analyse easy to gather data for the reference and track of progress? Don't you thing we have opportunity to execute 2 draws- with the release and just before placement?

[@InFin8RowingIntl]

Hey and thanks for the question. Please let me know more about what you mean when you refer to 2 draws, with one at the extraction..?

[@charleythora4037]

Very funny AND informative 👍🏼👍🏼 thank you (Is the carbon that of a braca oar?)

[@InFin8RowingIntl]

Thank you for the compliment. I hope you have subscribed so we can continue to entertain you. And for your guess. Nope it's not. Clue... It's a close up on a boat so I'm looking for the manufacturer

[@charleythora4037]

@@InFin8RowingIntl Empacher then? (And yes …subscribed )

[@InFin8RowingIntl]

Nope. I will see if anyone else guesses and then will give the answer

[@mangolassi_.]

Does "quick hands away" actually have any negative effect on the flow of the boat? I mean the mass moved during this movement is rather small and there is no relevant friction.

[@dermotbalaam5358]

Similar to what Drew Ginn said in his video years. Will it make the boat go faster?

[@InFin8RowingIntl]

I don't know Drew Ginn, but will have a look. And yes. It really does.

[@vandematharam509]

good one.. spelling mistake 21st second ,you have written "rovovary"...! 'recovery "is correct

I spell terribly so I'm only surprised this is the first one. Thanks

56 years and have never heard of it called the draw. must be a local word used for this.

[@InFin8RowingIntl]

I am sure there will be a few terms that I use that may not be the norm. I plan to do a vid on how to fix "jazz hands". This is what I call skying the blades. Hope you found the context useful though...
