How Did Vestas Sailrocket 2 Smash the Sailing Speed Record?!?!

In this video we talk about how Sailrocket 2 works, including how it smashed through the 50 knot foil cavitation barrier to break the sailing speed record at 65.45 knots (121.2 km/h) over 500m.

This channel is criminally underrated. Great job.

Great video. I grew up cruising Mexico and the South Pacific, and follow (lightly) sail racing, so I learned about SailRocket 2's record years ago. However, this video provided a very concise summary of the mechanics, and I really enjoyed learning all of those details! Thanks for taking the time to create this!

This is great content. I like easily consumable bites of pure knowledge like this. Keep up the good work!

[philiptorrens]

Thanks for this. I'd stubbled across videos of SailRocket years and years ago, but never really understood the tech until your explanation. Fair winds to you!

[MattBaker]

I watches the whole Sailrocket project from start to finish. I was amazing the ups and down the crash and the indomitable spirit of the team. Thanks for sharing their triumph with us.

Great video...informative, to the point, not overly long, and no BS.

[HJB._]

Yes, this channel is really criminally underrated. Great job.

You explained a fairly complex subject in a way that anyone could easily understand. Well done! I grew up on the Chesapeake Bay and spent the summers of my youth sailing. When I got a little older I was fortunate enough to get an opportunity to sail on one of the Chesapeake Bay Log Canoes. I spent a year racing on the canoes which was a truly memorable time. Going fast on a sailboat is something everyone should do at least once in their lives. If you are ten feet out on a board it's even more incredible!

Despite its limitations, sail rocket 2 is indeed one of the coolest sailing contraptions ever devised.
A spectacular feat of perseverance, engineering, and bravery.
Don't care one little bit if there's only 1 place in the world it can sail that fast. 👍

I think your channel was the one I had mentioned Sailrocket2 as a comment. I had no idea that it was so specialized and had so many shortcomings—they certainly didn’t highlight those in their vid clip. Your knowledge about foil dynamics is quite impressive. Thumbs up!

I've been fascinated by Sailrocket 2 for ages, and tried to watch all the videos I could about it, but I hadn't understood the mechanics of how it worked until I this video. It's way weirder than I thought it was. Great video!

Proud to have been part of the Vestas team that built this beaut!

[mikublueavm]

It may be a one trick pony but man is that a cool trick.

I am from Walvis Bay and did articles on Sailrocket project for local newspaper. Larse and Helena were on project. Wonderful people and so were the other people who worked on Sailrocket.

The use of a wedge is interesting and something that never crossed my mind. I remember seeing this same concept of the X15. It’s so counter intuitive. Great vid!

[KlingbergWingMkII]

Amazing! I track this kind of stuff all the time (I'm an aero eng) and I learned new cool stuff today, thanks!

[MLambdaman]

Well explained and straight to the point. Good job, sir.

[jonathanlevine]

As a speed sailor myself (TriFoiler #23 "Unfair Advantage"), I've been watching Sailrocket since the beginning and admire how fabulously bonkers it is. I'm glad you touched on the (obvious to anyone paying attention) one-tack limitation - scream down, tow it back. Great little vid.

[LoanwordEggcorn]

Thanks for another wonderfully clear explanation.

For the relatively static conditions there, one could have a teardrop ladder foil above the cavitating foil to get up to speed sooner. Might cause some drag in wave crests though.

[crcpeart]

Great summary ! and Paul Larsen.... brave man to pilot at those speeds!
