71 – Why We Swim

Recorded on Friday 10th April, 2020, with Harry Knight, Ru Hill, Will Forster, and Teale Beckenbach


This was our first COVID-19 Lockdown podcast which we recorded remotely from our various houses.

We all spoke about our current situations and how we’re passing time while we’re all at home. Will has been splashing in his pool, Ru has been dodging the law, while Harry has been making Jerky and Teale has been leading the live stretch and strength classes on the Surf Simply Instagram…


Surf Simply’s Coronavirus Situation Update:

With the current worldwide pandemic, Surf Simply has had to shut it’s doors. Ru walks us through how we’re planning to keep the business afloat, and at the same time support our staff through this crisis.

He mentioned the Earthquake that hit Nosara in 2012 as well as the Solar Storm of 1859 as potential issues that we’ve been thinking about, as well as this Guardian Article. Ru also suggested checking out Episode 63 of this Podcast as well as his AT-MEX talk about how Surf Simply is set up.


INTERVIEW: Author Bonnie Tsui 

Teale and Harry were able to talk to Surf Simply regular Bonnie Tsui about the imminent release of her new book, Why We Swim

We last spoke to Bonnie in Episode 61 when she first mentioned that she was working on this book.

Bonnie mentioned writing an article for the New York Times in 2014 that provided some inspiration for the book. We also spoke about Icelandic fisherman Guðlaugur Friðþórsson who survived for 6 hours in arctic waters in 1984.


MAIN FEATURE: Will on potential for hydrodynamic advances in surfboard design.

Will took another dive into his great love of motorsport by looking at some of the aerodynamics of formula 1 race cars and thinking about what might be incorporated into surfboard design.


Harry and Will both mentioned Ricardo Rossi from Red Fluid Dynamics. You can see in this image the high pressure of the boundary layer at the front of the board.

this picture shows the computed water pressure from the CFD simulations we recently performed for @sequoia_surfboards to analyze the performance of the Carlos and Toro models in planing/take off conditions. From the pressure maps you can see how the Carlos has more suction/less lift in the tail compared to the Toro, with the pressure minimum located towards the end of the board near the central fin, providing greater hold during take off and higher responsiveness in powerful surf. Water pressure and lift is higher in the tail of the Toro, with the minimum located close to the front fins. This gives the board more stability after taking off and while initiating your turn in medium size waves #surfing #surfboards #design #cfd #openfoam #simulation #research #innovation #technology #science #hydrodynamics #fluiddynamics

You can see in this video the use of Diffusers on the tail of surfboards.


Will and Harry made several references to the difference between older F1 cars and more modern cars with all their aerodynamic packages. In this image you see a 1955 Mercedes W196 next to a 2013 Mercedes W04
