Super. Well done! Send us more of this tips.

Your videos, Nils, are a pleasure to see, have a nice tone and are sympathetic (and still getting better...) The trim explanation could have been more technical. You could explain more detailed how the downhaul modifies the profile and reactivity of the sail. In the end it is not about the cm plus or minus but how you see and decide yourself what the best downhaul for a given situation is. John Skye told in the last windsurfing podcast to Maciek that if a good amateur surfer would take Macieks material with the perfect trim he would be nearly as fast as Maciek. But if the same good amateur surfer trims the same material himself, he would be far behind on the water. So I am wondering how to achieve this difference. Linked to this, how do the manufacturer decides where to put the downhaule dot. How right and exact can they be with it given that every sail is a bit different. Thanks, Peter

Bring on the fin video...!

👌🏻🤙🏼 thanks , I also noticed with shorter lines I achieved a better position. Cool video !

Packed with good advice. TY Nils.

Interesting video Nils, I will stay tuned!

Thanks again Nils. Great job👏

I liked your technical explanations! Grossartig!

nice video Nils, thanks for the tips!

Cheers mate 👌 Keep up the good work!

Wonderful! Thanks. Please keep going on.

Thanks for sharing 😊❤️

Great video. I just tried longer harness lines because I should be faster then. My GPS told me something else and now you confirmed that. Really helpful tips.

thanks for the tips, much appreciated

Looking forward to the video on fin!

I am not a speedsurfer, but these kinds of videos are super insightful. E.g. i should also try moving my mast back when i feel my board sticks too much in low wind. Thanks!

Thanks for this video

Very useful, thanks! It would be interesting to see how far are old (1990-2000) slalom boards comparing to newer ones?

Thank!!!! All sounds logical 🔥🤙🏻🤙🏻🤙🏻

Thanks Nils, that some good insights into your experiences with speed tuning. I'm looking forward to your thoughts on fins. Can you please also mention use of weed fins which is quite common around my sailing spots because of shallow and weedy conditions.

Helpful!

+1 on the lines! Everyone is running 34"+ and I'm on 26" for wave (waist) and 28" for slalom (seat harness). Have a set of 30" that I'll test for speed. I'm 192cm but with relatively long legs, that might explain why I like shorter lines.

Great insights! There can be a downside to using shorter harness lines. I missed you pointing that out. Compared to flat water and choppy (slalom) conditions where it might not be the best option and dangerous even. :)

Hi Nils ! Really useful video ! I learned a lot. Just have a question about the battens tension : what do you mean by "i like it with tension". I mean for batten #2, #3, #4 you say no tension, so i guess you just squeeze until you feel a tension and add 90 degrees of tension right ? But for battens #1, #5, #6 and #7, how much did you add after feeling the tension in the screwdriver ? I usually use no tension for #1 (why do you want tension in the loose leech ?), and add 720 degrees more for #6 and #7. The #5 is with 360 degrees more then the feel of tension. Is that right ? We often say that you might remove the wrinkles but my sails are a bit old (warp 2016) and i think it relaxed a bit so if i remove the wrinkles the tension is really high ! I'm a bit disappointed because i don't find a definitive answer to my questions. Thanks for your vids, discovered you a year ago and didn't miss one since ! Greatings from France !

Hey Nils it would be interesting to know your technical specs as well f.e. height and weight

Thanks, very informative! One question: Do you always use SDM masts? Have you tested the same setup with RDMs? Or for speed and slalom sailing the RDM is just considered to 'soft' for the average male rider? Thanks!

Hi Nils , you changed to shorter harness lines - but is that on a seat harness or waist harness for speed ?

Have you tried the 5.5 on a 380 mast?

✨👍 Like it. Good explanations. Shorter Harnesslines for more Speed: „Nobody wanted to believe me“ - Your confirmation feels so good 🤙😅
