Here is where I intend to publish my modeling of the mechanics of rowing.

Most of what I will publish here is based on a few sources on the web.

- Physics of Rowing for the basic equations
- Bill Atkinson’s page on modeling the rowing stroke
- A MatLab model by Marinus van Holst

Nothing new here, so please move on to one of those links now for some interesting reading.

What I have done is:

- Created a Phyton/NumPy model based on the equations by Marinus van Holst
- Slightly improved Marinus’ model
- Generate a lot of numerical results
- Use the model to calculate rower power for rowing world records in various boats and weight categories, and compare these number with available data

Why do I publish this if it’s nothing new? Basically I hope to get some reactions, especially hoping to improve the model, perhaps discover a few discrepancies. Find some people who are also interested in the physics of rowing.

I intend to use this blog to describe my model and the results. I have a family, a job and also spend a lot of time doing the actual rowing, so be patient. It will take time.

I will not explain rowing jargon like “racing the recovery”, “scull”, “oar” or “catch”. I leave it as an exercise to the reader to find the meaning of those terms. Go to a boathouse and talk to a rower. We love to talk about our sport, you know.

J. M. GomezI found a new rowing model that fits in with you work.

It is in thread called “Designing a fast Rowboat” on the Forums on boatdesign.net

http://www.boatdesign.net/forums/

The paper is:

Thank you.

John AitkenSander… I am trying to put together a simple spread sheet model for rowing parameters. I have been reading and using your postings extensively,.. I have a few clarifications of your terminology which I would like to discuss with you..do you have an email address I can reach you .. Mine is john8ken@gmail.com.. I have not seen recent postings on this site and am not sure if it is still active…. Thanks… John Aitken

Peter HuntDear Sander,

I am currently writing a paper regarding an aspect of the physics of rowing, and was wondering if you had any power-time graphs for a sweep stroke.

Yours faithfully,

PG Hunt

sanderroosendaalPost authorPeter, I do not have them. Are you thinking simulations or measurements? By power, do you mean handle force (N) or really power (W)?

Peter HuntSander, don’t worry at all – I have managed to calculated peak force from the acceleration off a velocity-time graph.

With thanks,

Peter
