Laser (ILCA) S-turn technique when sailing downwind

International laser class association, " formerly known as laser" ?🤨
Super interesting at any rate..cheers

Awesome simulation and really interesting results!

Really interesting to know that you can get so much extra power out of these S-turns. They definitely gain you a few places near the back of the UK ILCA nationals.

Got to add this dissertation to the reading list. My understanding was that these turns helped you surf the waves, and keep your speed up, while not ploughing forward into the next wave until you see a gap. However, it never made sense why it was faster than surfing diagonally down the waves for several boat lengths in alternate directions (which wasn't faster than someone sailing in a straight line when I tried it)

Wow. Thank you !

how does that square with Rule 42, for ILCA Lasers?

Should I pull up my center board for the s turn? I'd assume so right but wouldn't that make it a little harder to turn accurately

Fantastic!

It would be interesting to see the results of this study at different wind speeds. I imagine that the differences in downwind angles to sail an asymmetric spinnaker boat downwind in light vs heavy wind would be relevant to how to sail a laser downwind in various wind speeds also.

Ask Sir Ben ! He would never tell you all this. Top secret ! xxxxx

Great information, though I would have preferred actual human voices narrating. I muted and used captions instead.

thanks a lot

thanks bro~~

Super interesting. What do you think is the impact of the frequency? Does it also help to do the S turn, trimming and rolling more slowly? (That way you don't risk to get a penalty.)

You will probably get a penalty for this, at least with bad judges definitely

Is this even ok with rule 42?

Awesome!! Brilliant model! Thanks for sharing,

This is amazing! Thanks a lot for sharing!!

Awesome! You should make one on snipes sailing downwind, with the pole and the flying jib and no spinnaker...

Huikeeta!
