Nils. As a ex shaper/designer of surfboards, wave skis, and to a lesser extent, sailboards, now retired, I'm still interested in speed related watercraft. I would like to ask your thoughts on equipment improvements/evolution you think could improve speed in sailboards. Are there restrictions on sail size in regard to managing their power rating? Can boards become even smaller to reduce drag? Lifting foils are efficient in lower power conditions/winds, but I don't ever see them ever overtaking non foiling boards. So, I don't even think about lifting foils in regard to speed sailing. But this is something that isn't very well understood in the average sailng community. Lifting foils are efficient rather than fast. Efficient does not necessarily mean the speediest. Cheers
Thanks for your comment, I was wondering. I guess cavitation is a problem above a certain speed? Foiling works in sailing because usually there is more drag from the hull, but here the speeds can be greater than the benefit of a foil?
One thing only people that windsurf at strong winds can appreciate is the risk of board fin not holding. You can see how the yellow board is almost side sliding in the water. Sometimes if unlucky air bubbles arrange themselves in a way that fin looses its grip in split of a second. At 60km/h it is not fun! The choice of the right fin type, its dept and thickness and shape ... is crucial.
It's called cavitation and is really bad, yes, especially at 50kts. But in the channel there seems to be a lower risk of it because of the wind direction. Not much pressure on the fin there. In sailing 50kts is something like a fluid dynamics barrier. Around that speed cavitation is almost unavoidable, even with the best materials... Ask AC75 pilots 😁
@@WindsurfingNils Es ist halt schon ein ziemlicher Nischensport geworden. Bin als Bodensee-Kind seit 1979 (als damals 10-jähriger) dabei, da standen die Mütter noch beim Rathaus Schlange, um einen von 200 Plätzen in den Surfbrettständern im Strandbad zu ergattern. Heute sind 9 von 10 Ständer abgebaut und 2 Surfbretter und 3 SUPs gammeln dort vor sich hin. Krass andere Windsurf-Zeit damals, geradezu ein Volkssport - und das ohne RUclips- und Insta-Promotion...

At first I was thinking, you probably need a helmet there. But in the video with the helmet, I was thinking, a helmet will not be enough if you fall right there. Good control, high risk.
Hi. Yes you are missing something. However, you're not alone in that regard because most people misunderstand the technical aspects of lifting foils. Lifting foils are a device that allow the negation of the effects of large and/or innefficient hullshapes. Sailboards do not come under this category of innefficient hullshapes in regard to high speed. Lifting foils efficiency lies in the low to mid range of power. Simply put, the high speed efficiency of a surfboard/sailboard is greater than a lifting. The reason high speed planning craft such as racing power boats don't use foils. Cheers.
Great job, also nice to some pretty classic gear. Did you design your own board? Is it special speed sail? The edge is really dangerous, a crash in this speed is often painful🤠 At least thres no sharks in the channel, thres plenty of them just outside the town🤡
yes, a little offset is always there with the 40 boards with 19 fin, seems to be the sweet spot with drag and offset, spinoff is still different though, because the flow around the fin is still intact with this offset
Why don’t they set it up with instead of sand bags in a channel use floats anchored like you would see if there was a oil spill and do it at a different location so you could adjust the floats for optimal wind directions? Probably Safer to hit floats if you hit them at speed too
There is two methods used, the quick one is using a specifically designed GPS with set gates for the 500m distance, and there is two cameras set up at the starting point and end point of the 500m+ tolerance that is used to varify records as this is the most accurate system. The difference between the cameras and GPS is usually less than 0.2 knots so GPS is already quite accurate
@@WindsurfingNils Thanks for the answer and congrats for the result, I appreciate / enjoy your vids What gps could you recommend me to measure my speed ? Thanks
They tried ii years ago going down the canal with a now cam sail in high wind. It was almost not possible to go around the slinghot corner neither go down in such a deep downwind course
Read my comment above in comments I say the max speed achieved by realistic measurement is mine as well at 104km/per/hour measured on police radar in the early 80s the radar checked later reading 4km/hr slow, then outright record as in comments,then 102km/hr on radar again after speed trial event all speeds non camber induced sails WR set using Niel Pryde RAF Wave 4.7 in40kn wind ,102km/hr on same equipment in40kn wind 104km in44kn gust on old style 5.4 sail .
49,85 kn 👏🏼👏🏼👏🏼 Aber ich frage mich wirklich, ob es Sinn der Sache sein kann, mit soviel extra Gewicht (Blei?) zu fahren? Zumal das den leichteren Fahrern erst recht alle Chancen versaut. Wenn ich mir die ausgebeulten Shirts ansehe, tippe ich auf 20 kg und mehr?
Es macht sehr viel sinn um die Stabilität des Segels hinzukriegen. Ich bin leicht und ich spreche aus Erfahrung:-) es drückt dich sonst immer wieder auf und das heisst… geschwindigkeitsverlust.
Ist schon klar, kenne ich ja selbst. Beim Pferderennen gibt es ja den Gewichtsausgleich, damit alle Jockeys gleich schwer sind. Aber wenn eben auch die großen schweren Personen aufstocken, kann man da ja gar nicht mehr rankommen.
I didn't know this existed. Looks awesome!!!
Thanks for sharing this adventure Nils. Looking forward to the next one!
Großartige Leistung von Dir, in Deinem ersten Jahr dort!-))👍🤙💪👏
Vielen Dank!
Its an amazing place to be. i saw that your board is drifting, so there is a lot more to win!
Holy shit.. this was close to the edge😮
And big congrats on the speeds!
yes, only way to get a little flatter water is to go close ;) thanks!
Good job on the speed, and the videos.
this looks so freekin dangerous! Canot image crasding at +90km/h speed. You guys and girls are true mordern gladiators!
sailed super passive the first few days because of the fear of crashing in the back of my mind, then slowly got more comfortable in the channel over the weeks...
Als du eine Vollbremsung am Ende eingelegt hast, bist langsam in die Richtung meines Topspeeds beim Windsurfen gekommen..🥴😂
:D:D nächstes mal mit wing durchfahren ;)
Aber bitte mit wingfoil 😂
Amazing Video & speed you did!
mille grazie!

@@AWildBard Yes, that's right. I was wondering how far can boards can be reduced in size and how large sails can be handled.
@@AWildBardHave they experimented with the aspect ratio of the dails. Since they also have to be tuned for a specific speed range to be obtained.
Awesome!! Amazing!! Next year 50knots for sure!! 👏👏🚀🚀💪💪🔥🔥
Don't know if I will go next year, temptation is there for sure ;)
@@WindsurfingNils Nils not going in not a option!! You have to go!! Start saving some €€€ from now on to go next year!!
Awesome blog as always Nils
thanks Philip!
I really enjoyed your videos for the speed challenge. I hope you do it again
Tanks, let's see...
Wow, impressive. Any reason for you guys to run so dangerously close to the upwind border ?

Gratuliere zu 5000 Abonnenten - mehr als verdient! Schätze deine Videos sehr. Viel Erfolg dabei weiterhin!
Vielen Dank, ist schon krass wenn Ich mir überlege wieviele Jahre und Videos es gedauert hat um auf 5000 zu kommen...

It seems like keeping the board down and from becoming a sail in itself is a lot of the challenge.
Meeeega video 🎉❤🎉 and CONGRATS
Dankie!
I just read on Facebook that Farrel O'Shea has passed away 😔 R.I.P.
great content Nils, good times mate
thanks Jason, hopefully until next year!

Amazing Speed Video😮 almost 50kots 🙏
Fantastic video. GD frightening.
This is outstanding. But Im missing something here. You can achieve better speeds with foils right? So, the speed record is for traditional rigs?
in windsurfing foils are currently around 15 knots slower...

Good sport for the folks who never learned to gybe
are you saying antoine albeau can't gybe
@@orlandosadliksailing joking
gotta figure out how to do that!
Wow!
Great job, also nice to some pretty classic gear. Did you design your own board? Is it special speed sail?
The edge is really dangerous, a crash in this speed is often painful🤠
At least thres no sharks in the channel, thres plenty of them just outside the town🤡
You seem to be permanently on a 5° spin out? Is that normal at this speed?
yes, a little offset is always there with the 40 boards with 19 fin, seems to be the sweet spot with drag and offset, spinoff is still different though, because the flow around the fin is still intact with this offset
sea knots or land miles ?
Why don’t they set it up with instead of sand bags in a channel use floats anchored like you would see if there was a oil spill and do it at a different location so you could adjust the floats for optimal wind directions? Probably Safer to hit floats if you hit them at speed too
It's been tried...it didn't work.
I think it's because of the weight by being static it won't let any swell builds up
Nice idea
What kind of gear is used to mesure your speed
There is two methods used, the quick one is using a specifically designed GPS with set gates for the 500m distance, and there is two cameras set up at the starting point and end point of the 500m+ tolerance that is used to varify records as this is the most accurate system.
