Super that you bring out this topic of too much downhaul tension. It's a real sail and performance killer. I've been there and really felt stupid afterwards when applying just the right downhaul and the sail was better especially in gusts. For s slalom guy wave sail was odd to tune and has totally other way of trimming. Maybe that could be a good topic. Thanks Nico. I'm starting to like this stuff 🙂

If I win the lottery, I will hire you as a personal trainer

The sail twist is also needed because of wind gradient (change) at different heights above water level. It does not matter when someone is stationary because then the apparent wind is the same as the true wind - but when you start sailing then the apparent wind - both direction and speed - changes depending on the height above the water, because the true/stationary wind speed decreases significantly just above water level. So a "twisted" sail reflects this change of both speed and direction of the apparent wind whilst windsurfing. The bigger the sail and board the bigger the effect, mostly because with big sail and board (or foil) the board speed can be as much or more than the true/stationary wind speed. I do not do foil but a formula board can easily plane twice as fast as the wind speed, thus the wind gradient effect on apparent wind direction becomes very pronounced.

Great tips, and you explain things very well from the perspective of the rider. However I would like to mention the technical / physical explanations, as they helped me understand these things: 1. Sail twist is important due to the gradient in wind direction between water surface and be mast top, as others have pointed out. This gradient increases with board speed compared to wind speed. 2. More curvature across the chord of the sail increases aerodynamic lift at low speeds and allows a greater angle of attack. The angle range between no lift and stall is smaller for a flatter sail, which is what you refer to as a more nervous sail. 3. The mast curvature must match the sail curvature. I have noticed that I was using the wrong mast if I had already applied the correct amount of downhaul yet the battens still had difficulties flicking around the mast on a change of tack. Of course one may be safest to buy only from one brand, but if you really want the sport to become more accessible, then give us some tips on what to look out for when we mix and match different used material, old and new.

I love this kind of technical stuff!

Another clear and concise high quality video. Please keep it coming. Highly appreciated!

Thanks for all your work in your videos! They brought me back to windsurfing after a 25 years brake. Man, how much changed in rig and board technology! Starting now with some new and not too old used gear and having fun now on the water again. Thanks for your great motivation and tips in your vids!! Keep on riding!

I love your shops goal- “To get as many windsurfers back on the water as there were in 1976”- THATS AWESOME!!!!

This is a great video Nico and I really appreciate all your content as my 12 year old watches them religiously... Tha ks again and all the best for your racing season ( p.s. the videos are helpful for me as well 😄 )

For some reason, KZread didn't notify me for this new video, but thankfully I'm subscribed to the newsletter and got the email :)

Can you make a Video about how to tune your batten and camber rotation butter smooth? Especially for foil sails and slalom sails most sails come with a too hard rotation . I think that's a huge problem for many windsurfers who don't know how to improve that

Too stiff or wrong curve mast can also cause that for cambered sails. Or too little downhaul...

As far as the cams not rotating smoothly would more outhaul fix that to ?

@Statek63

@@bicboy49 some sails have cam spacers that can be added or removed to help with smooth rotation. Downhaul and outhaul should be optimized for general sail performance, not to fix cam rotation problems. Myself I prefer adjustable outhaul for big and mid-sized cambered sails ( so from 12 sqm down to around 7 sqm ). For smaller sails I use mostly fixed outhaul. Cambered sails will always need a bit of a sharp pull to rotate the cambers - I adjust the camber spacers when even that sharp pull does not help and when the cambers need to be kicked into place.

Excellent instructional video. Very good blend of technical knowledge with practical application explained very clearly.

Thank you Nico, the explanations are always clear and usefull!

Great video as usual! Thank you!

Amazing tips and video, keep it like that 😁

Good info, but also big thumbs up for the production values of the video. Really well done and it looks and sounds great.

Tipps for suitable trimming tools like the (Trimmknochen😅) or technics for downhawling, can you show us something for this point of view?. Race sails for example have very high trimming powers. Nice video I think. Go for it, Nico😉

Great video! Wish I had more time to go windsurfing/make mistakes!

super poradnik! Dzięki 🤙

Great top clear infomation as always 😎👍

Another fantastic video. Thanks Nico!!

That's great content and it's always nice to hear sensible advice. Please do another tuning tutorial on a more advanced and technical issue: cam inducers! There's so much new to talk about: batten tension; what if they don't 'pop' nicely; what if the very end of the batten doesn't 'pop' all the way; what if only the lower or upper one doesn't 'pop' properly and the sail forms an 'S' profile? Word on the 'Ufer' is all very well but this is a dark art that deserves its own lecture. There are so many nuances and ways that cams can misbehave. Please, Nico, please!

Totally concour with Stephen. My 6.6 Evo behaves totally different to my 7.4 which I believe is now down to baton and cam tuning... I fly on the 7.4 but as the wind picks up and I change down not only am I slower but the 6.6 even looks different when rigged. I need advice and qucik bcs if they are anything like my Point 7s I am about to start cutting batons down to find that perfect S shape.. or ruin a perfectly tuned sail bcs its my sailing lol

Terrific stuff !! Thank you very much, all of your videos are super interesting !

Very professionell video with personal touch. If I meet you sometimes in a windsurf spot, I spend you a Pizza for trimm my sails perfectly.

Nice to see the new panasonic S5 mark II is working well. Autofocus has improved a lot so we get a smoother video experience. It's with good video equipment the same as with the right windsurf gear;)

Well explained tutorial.

This is exactly what I wished was easy to find information when I started windsurfing years back… and still of course as most of us do …. Need reinforcement and re-learning

Danke für die vielen guten Tips!!!

🎉🎉🎉Bravo nico you became like a body🎉🎉 builder its normal with so much fight with the wind it came alone, your shoulders are with perfect analogy out,super nice..

Nice video!!!!!

Very entertaining to take class in your windsurf school ✌🏼

У меня старый парус NP Slalom MkII - не могу найти инструкцию на него, мачта FX100, вроде должна подходить, выставляю размеры как указано, набиваю, - не переключаются камберы, ну т.е. раза с третьего может быть перекинутся. Меток на нём насколько должен быть твист - нет. Камберы вроде рабочие (там эта их система UltraCam). Одна из металлических бобышек была с сорванной резьбой, я разобрал, поменял. Все "шапочки" лат стоят на ближайшем к парусу отверстии (там, если кто не знает, три отверстия, есть ещё с двумя. Видимо если лата сломана, то можно переставить в более дальние от паруса отверстия и камбер будет более натянут, но у меня в самых ближайших к парусу, т.е. должны быть самые прослабленные). Смотрел видео как настраивать и как ремонтировать систему UltraCam, но у меня и так всё по минимуму. Лето закончилось, теперь буду только в следующем году пробовать, но сейчас смотрю - наверное по мачте я всё же не дотягивал, хотя ну уже некуда дальше было. Наверное надо чуть подлиннее выставить удлиннитель.

Great video Nico, nice and clear explanation. Can I ask: If you don't have markers on your sail, do you check the downhaul of the sail when it's flat or when it's upright? Would love to hear your answer and why.

@alfskaar489

11 ай бұрын

I do it flat. Remember any downhaul marking is a reference point not the perfect trim for the conditions and the rider. If the sail have to little downhaul you will feel it to. It feels heavy and don't accelerate like holdeing a dor against the wind. All sails need to be sailed to get the perfect trim. Also the mast length from same brand and type is always slight different. Measure the mast length and write it on the mast if you have multiple mast that are the same.

this is a good question, but may you explain what means upright in this context. thanks Nico for your great videos

So can you talk about adjustable out haul and when and where it is useful?

Thank you Nico. Very helpful to a lifelong NP V8 user.

This is really useful for me as a rookie or newbie to windsurfing 😅

Hi niko your videos helps me so much keep up the good work

Great video! what is the surf spot in the video? seems really nice :). Good for all directions?

Hello Nico, thank you for the very informative video. I have the following problem with my 3 camber sail, Northsail 7.4m², the mast hand always has to compensate a lot in strong winds and is always very stressed. I sail a longboard/raceboard fanatic mega cat 1995. Do you have a tip. Thanks very much.

Vielen Dank für das Video. Leider bleibt ein nicht unwesentlicher Trimm-Aspekt - die Spannung der Segellatten - unerwähnt. Zumal diesbezüglich die NeilPryde-Segel ein negatives "Alleinstellungsmerkmal" haben: Das einzigartige System mit den umklappbaren Plastikverschlüssen ist extrem anfällig für Materialbruch. Ich fahre seit Jahren nur NeilPryde-Segel (und liebe sie), aber die Lattenspanner sind eine Katastrophe. Bei meinem neuen Speedster 5.2 lassen sich 3 Latten von Anfang an überhaupt nicht korrekt spannen, da sich die Plasteschraube überhaupt nicht bewegen lässt (da offenbar Gewinde und Schraube nicht aufeinander abgestimmt und wie verbacken sind). Bei anderen Segel sind im Laufe der Zeit die Flügel der Schraube abgebrochen. NeilPryde ignoriert das Problem beharrlich (Anfragen im Kontaktformular werden nicht beantwortet), Ersatzteile ("Cent-Produkte" aus Plastik) sind auch über die lizensierten Händler nicht zu erhalten. Sehr schade! Wie handelst Du das bei Deinen Slalomsegeln?

Every days a school day!

Trimming is the best way to get connected with fellow weirdos on the beach :D

Thank you, will try to improve the rigging

Some years ago Neilpryde use to do rigging videos for their sails. Now they rely on content creators to do so. I've searched for a rigging guide for my then brand new Free Flight 5.7, but found nothing (even for a 2021 one). Found myself by using it, but I would have appreciated that the rigging video. By the way my sail is heavily featured in the mast part of the video. (And I don't have a NP mast, shame on me, but the one I have seem to fit quite well).

I love to see you do well in pwa. But incresingly on the foil. Could you do a video about realy pushing the foil? I feel there is jet mutch to be said. Grüße.

thanks !

I've noticed that using a constant curve for a Flex top sail Is like too much downhaul. What about reducing the extension to balance It?

Thanks, thanks, thanks 🙏

Nico I see you using adjustable harness lines. Which ones do you use please?

slt nico I have a problem with my 8.2 evo 13 I have trouble going upwind with 118L yet the sail is taut with the armor as it should and practically no tension when listening, I have to really put my foot forward of matte

How do you decide to use top or bottom clew position?

@stephenmartindale

11 ай бұрын

Personally, I've never held a sail that behaves as nicely on the lower clew as it does on the upper one so I only ever use the lower one when I'm on my smallest, already, and still overpowered or struggling with the sea state - the lower one seems to allow the leech to open and twist out, more, and feels a little more forgiving to me. The upper clew seems to match what the sail maker imagined on the lofting floor.

Guilt of mistake #1 back in '99/00 on Maui. Never rigged a Naish Nalu 4.2M until that season. No fun on the water until the rep. pointed out my mistake. Sweet sail when properly rigged. Ezzy only user since '12. You gotta be a real dolt improperly rig and tune Ezzy sails. Built in tuning aids and marked at the factory for the medium setting.

I hadn’t yet heard about the 45 degree angle of the apparent wind at speed accounting for the twist in the sail. How much twist should my foil sails have? 6.0 Sailworks Flyer and 6.4 Duotone F-pace. I definitely overdownhauled the flyer last week as the sail felt lethargic and hard to control.

@@jimbojetset3306 Read my post above, the twist is also needed because the true wind speed varies with height, thus the apparent wind speed AND direction varies with height above water. The twist also helps to reduce induced drag at the top of the sail but that is another subject...

My current board is from 2013, so i could use a new one.

What's about the downhaul and the outhaul tension for foilsails, I hear there it is slightly different. And a following question: I bougt a foilsail, that brings me into trouble: with strong downhaul i have too much loose leech and when i do it some less, then I ll have a bad rotation around the mast, this with a mast that is recommended what do you suggest?
