Maxime Nocher in St. Barth
We arrived to St. Barth the 4th of June in the evening, the next day, we were able to ride in "La Baie des Flamants" for training and to check the best wind direction to optimize our chances of record. Normally, we thought to have the best conditions (East orientation) for the next day, the 6th of June. We went to ride in a big lagoon to test the wind and I tried to choose the best material but unfortunately I wasn't able to ride with my 9 meter and Julien even with his 11m had lots of difficulty to go upwind... We realized that the east wind is too hot and not strong enough.
The 7th of June the weather was not the best, we had 15 knots NE, but we decided to lauch the crossing from St-Barth to St-Martin (34 kilometers). We called the security boat, which would come in 1 hour. During this hour, we prepared our material, analyzed the wind, it varied from 5 to 20 knots due to the cloudy weather. First big question, the size of the kite! I decided to take my 9m Dyno with 24 meter lines! Julien and Remi decided to use the same size. When we arrived at the start line, the wind was stronger than expected.
The start is done, and after 10 minutes of navigation I managed to get some distance to Remi and Julien, the problem was, I was alone, I didn't know the 100% correct direction. After a few minutes the boat opener joined me to help me for the cape and at this time we were able to finally see Julien and Remi. The speed of the opener boat side of me was around 30 knots. After 25 minutes of crossing, we saw the Saint-Martin coast line and I thought I'm late comparing to the last record! So we tried to go even faster. In the end my final time was 39 minutes and 8 seconds. I couldn´t believe it. This record is the new record for a crossing from St-Barth to St-Martin for kitesurfing and windsurfing. The old record was owned by Alexandre Caizergue since 2009 with a time of 44 minutes.
Thanks a lot to North Kiteboarding and ION to support me for this incredible experience! I'm very happy to have succeeded in this challenge.
"The Need for Speed", African Course Racing Championships!
Racing is more than just the moment when you cross the line – it´s all about training, technique and in the end - the competition. Physical and mental strength is the key to success, but perfect gear helps a lot. 2011 the production class was introduced and has made racing much more accessible to everyone all over the world and has made the sport a lot more professional too. Check out the new race video "The Need For Speed", shot in Egypt at the African Course Racing Championships and inhale the racing atmosphere!
Dyno 2013 - What's new? by Ken Winner
Low weight is a key feature of the Dyno and all measures have been taken to strip out materials that do not contribute to on-water performance. For example, there is no single-point inflation system on the Dyno simply because SPI increases weight without improving performance.
The performance benefits of low weight are mainly:
(1) the Dyno will easily fly when quite underpowered. The 17 will readily stay in the air when there is too little wind for an 80-kilo rider to plane on a big race board.
(2) when flying the Dyno up and down for power (as when racing downwind), the Dyno's low weight helps it to make a powerful upstroke.
Aspect ratio remains low enough for quick turning but high enough for good aerodynamic efficiency.
While the Dyno will work as a 4-line kite, it retains 5-line ability for these reasons:
(1) Easy relaunch in light winds. Even riders who like four-line kites often add a fifth line to make relaunch possible in super-light wind.
(2) Safety. When you need to get total, complete and perfect depower in half a second, nothing else works as well as a 5th line.
(3) Easy, safe self-launching and self-landing.
Thin tapered struts with semi-segmented and conical construction
Struts are tapered from a fairly large diameter where they meet the LE to much smaller diameters 25% back. The big joint with the LE gives more rigidity to the structure of the inflated elements. The taper to a smaller diameter provides lower drag.
The semi-segmented construction gives a smooth upper curve to the struts – an aerodynamically superior shape – while taking up excess cloth and preventing unsightly wrinkles in the lower surface of the strut.
The struts go to a conical construction at the 25% point. This eliminates seams and therefore removes a point of potential seam failure in the part of the strut that bends the most on the beach.
The 2012 Dyno has seven struts for extra stability – mainly appreciated by heavier riders taking the Dyno to the limit in powered conditions.
The 2013 Dyno is more narrowly focused on racing, which requires more flexibility and the lowest possible weight, so the new Dyno has only five struts.
The tip strut is closer to the tip to support the thin leading edge and provide stability during hard turning. The quarter strut is a bit closer to the tip strut so as to support the flat section of canopy between tip and quarter struts.
The large span between quarter and center struts provides the bulk of the power of the kite. This area is not heavily controlled with struts because it needs to be free to luff or fill, depending on wind strength.
More and different sizes
The Dyno was originally a light-wind kite but has evolved into a light-wind and race kite and now comes in sizes 7, 9, 11 and 13 in addition to the original 15 and 17.
The new 17 is larger than the 2012 Dyno 17 and has significantly more power. Sizes 15 and 13 are also more powerful than corresponding Dynos from 2012.
Graduated cloth weight
The inflated elements of the 2012 Dyno were entirely built of a light but extremely stable new Dacron. For 2013 we are keeping this lighter Dacron in the small-diameter inflated elements – the struts and the tips of the leading edge – while going with our standard, heavier-duty Dacron in the large-diameter parts of the leading edge. This heavier Dacron permits higher inflation pressures and thus greater stability in the leading edge.
We've added more segments to the geometry of the 2013 Dyno. This helps ensure good fidelity to design shape.
Owing to the fewer struts and lower weight, turning speed has been improved. This is most noticeable when flying the Dyno up and down on a deep downwind point of sail.
Leading edge diameter
Leading edge diameters are basically unchanged in the center of the Dyno but tip diameters are smaller. This change provides a bit less aerodynamic drag.
The new Dyno bridle has no pulleys. This gives a bit less weight and drag but also means that the 2013 Dyno must be flown on either (1) a 5-line bar or (2) a four-line bar with front-line safety leash.
Canopy profiles in the outboard quarters are quite flat for low drag. Canopy profiles at and between center and quarter struts are deeper and more powerful than in 2012.
Power vs. depower
The various changes have led to better power and depower.
The lower weight, deeper profiles and new geometry help the 2013 Dyno to relaunch quickly.
Sky Solbach Dyno:
"The new Dyno is something totally new and is hands down the fastest kite I have flown to date. It constantly shoots to the edge of the wind window while maintaining really consistent power delivery that carries you upwind. Downwind, the new Dyno is equally impressive. I can't wait to see what the North Race Team can do on the race course this year with this tool in their hands!"
