3 days Amstelmeer

Had 3 nice sessions in row on the Amstelmeer, exhausted now. But very nice training on the homespot, after checking my own sessions lately I concluded haven't really tested in gusty wind. Especially the 6.2 wasn't tested properly.

Saturday 61,05km/h / 32,96kn
All day on iSonic 111 and 7.0, a proven combination for me. Did test the Sonntag SL-P 40cm on some rougher water to my limits. A new 40cm record for me :). Also tried a tectonics talon 40cm for the first time (9.5% thickness), this fin felt a bit more low drag, but on GPS it was a bit slower. Hard to compare though in these gusty conditions.

Sunday 66,23km/h / 35,75kn
The first day on iSonic 86 + Severne Reflex 6.2. Had no rocket fast experience yet before (with this combination), but now at last the tuning was matching. Extremely gusty, did release a little bit downhaul and this was no problem (actually faster). A bit less than written on the sail. Stoked to do the fastest 10sec run in 2010 on the first time out with my highwind Amstelmeer surfstuff. To bad the wind was to much on/off for average improvement. Did survive 36kn+?!? gusts pretty good :)

Monday 63,3km/h / 34,18kn
Less wind, even more gusty... Only on the middel of the lake there was enough wind to actually windsurf.  Did spent most of my time parallel to the road, nice to surf next to the cars with 55-65km/h. I was thinking this should be a good way for advertisement. Wonder how effective this advertisement-action is, at least cars stayed right next to me :).  Used iS86+ Reflex 6.2. Stopped quickly since I didn't feel fit at all. Northern winddirection wasn't too bad. Only when sailing next to the cars it was tricky, one moment 20kn wind, a second later windsilence, a second later something like 25kn, nearly impossible to benefit from the windgusts. Again a Personal Record the Alpha-500!!

Kicked out of the top-10

A lot of high speedsessions are posted: . Soo many fast german speedsurfers now in the top-10, congratulations! Hope to see some pictures soon. Vollerwiek... The german speedspot, no speedspot in the Netherlands has proved to be faster, yet...

For me it feels not soo nice to be out of the top-10, I just couldn't benefit from the strong wind last week. Still it was a great experience being in the top-10 for a few weeks!!! But this is a new challenge, lets hope for another windy session :) and try to improve my PB again.  In the gpsteamchallenge I see germany didn't participate yet, too bad, this would have been a good month to score points ;)...

Jacques van der Hout his channel

Jacques is doing a great job for speedsurfing with his videos, the current number 1 of the world!!  Dispite the fact we share some history I simply respect the effort of making these videos. This is my top-3 below, out of the 12 available videos. I am a strong believer speedsurfing needs people that do think outside the box, this is a perfect example!!!

3)  The 60 seconds speedrun

60 seconds over 70km/h (38kn), now on video!  I like the way you see the nose of the board hoover over the small chop, just behind the front footstrap till the end of the board is in the water. Speedsurfing fast for such a long time must be great, something else than the 2sec peak speed ;)

2) The Alpha

I think the whole speedsurfing world knows about Jacques his quick alpha-500's. Here's one on video, and you can learn a lot. At this moment I am trying to improve my own alpha speed, still not really high, but there is progress!!  Also Jacques seems to be first in the footstraps before hooking into the harnassline. I am training to do so, have to get used to the extreme momentum is scary when hooking in.

1) Fast 10 seconds run in the Netherlands!!

This is fast for the Netherlands, funny to see little other details in board behaviour compared to La Franqui. If you really pay good attention you can see this is more broad than the upper video.

Just not good enough...

Many recordattempts, including myself hoping for an improvement in the "funranking" (let's keep it fun). Only 1 extreme fast run would have been great. But the conditions were crazy, nothing like "normal speedsurfing". Everybody was going slower than the wind at Da Curve & Brace.

When I speak for myself I had to trim a lot of control==> this costs looseness==> resulting in extra drag, this was my conclusion. The gusts near 50kn were mean often a big contrast to the nominal wind (about 35kn). Don't know if there is an actual speedbarrier in sudden increase of drag, for me it felt like yesterday the control needed was the limiting factor. For true records I believe the efficient setup has to be used, survival till one megarun (controlable thanks to increasing windstrenght along the run). Yes you have to be lucky, and worst case scenario you could end up losing dayranking without 1 fast run.

Too bad the wind changed quickly and the tide came up, I was one of the few lucky ones in the Netherlands with 5 runs...

My session:

Currently in top10 this month and year :)

Severne 7.0 speeeeed

Today while driving I thought lets do something crazy, walk almost 4km with 7.0 in the mud for a speedsession, would be interesting for sure. I was convinced it would be a mediocre session, and better do something new on such days is my vision. Result is more than I would ever wished for, I did a faster run on my 7.0 than I ever did before with such a big sail. Even my fastest 6.2 10sec run doesn't come close:


Sorry the speed is not in knots, don't want to calculate it right now.

Funny thing about today is there was no lead in my weightvest, only 4 fins. Soo I bothered to measure my total weight today, plus summer shortarm wetsuit, plus weightvest (including 4 fins), plus some small stuff, plus seatharnass ===> 86kg. I seem to have lost some weight again lastest sessions :(. Time to eat! Good news for me and some other, it is really getting easier to go fast even if your not that heavy. Couldn't believe almost being able to match Jurjen vd Noord his extreme fast 7.0 10sec runs. The big gear does feel a bit draggy, still the numbers on my GPS made me satisfied :).  Now 5x10seconds above 40kn with 7.0 on a bit more constant day!!

Conditions were not perfect, also not bad, rather gusty for the Brace. The spot is changing fast, it has been to long ago when I was speeding here. Might be faster nowadays, at least it was flat considering the winddirection, windstrenght, etc...

Congrats for Robert Seinen, he pushed again a fast run!!! I saw it was fast :), a bit faster than me.

My sailquiver experience for speed

Sometimes I am asked about a good sailrange, for gps-speedsurfing I have had many changes in sailrange which I like to share. One thing really changed mid-2007, I convinced myself to stick with speedsizes and train as much as possible with them.  Learned a lot about surfing underpowered, which wasn't always fun.

Below are the sails I bought and used for those periods:

before GPS_______8.0m2 + 6.5m2
11/2005 - 7/2006__8.3m2 + 7.3m2 + 6.3m2
7/2006 - 7/2007___7.5m2 + 6.9m2 + 6.3m2 + 5.7m2 + 5.1m2
7/2007 - 4/2008___6.5m2 + 5.5m2
4/2008 - 6/2008___6.7m2 + 5.5m2
6/2008 - 10/2008__5.8m2
10/2008 - 5/2009__6.7m2* + 5.8m2
5/2009 - 7/2009___6.7m2 + 5.5m2
7/2009 - 9/2009___6.2m2 + 5.5m2
9/2009 - 10/2009__5.5m2
10/2009 - 4/2010__6.2m2** + 5.5m2
4/2010 - 5/2010___7.0m2* + 6.2m2 + 5.5m2
5/2010 - 6/2010___6.2m2 + 5.5m2
6/2010 - now_____7.0m2 + 6.2m2 + 5.6m2 + 5.1m2

*Could borrow 2 periods a bigger speedsail from Peter de Wit/Kater, to make it possible to train a bit.
** Thanks to Martin van Meurs I could buy one off his 6.2 (everything was sold out), after wrecking my own 6.2...

- I like a +- 7.0m2 to get good training (in wind below 18kn), I even think a bigger sail (7.8-8.6) gives even more good training opportunities, maybe something for 2011 ;)
- The +- 6.2 is most important for powered up sessions and dutch competition
- The <5.6  is only needed if you aim for records/ or simply like to speedsurf in 35kn or much more (depending on windsurfer's weight)
- 2 sizes sailquiver is possible, but absolutely not fun all the time, I had to choose lightwind or highwind combo. An 1 sailquiver is frustrating (at least if you trying to do your best).

[preview] Fanatic Falcon 2011

As a former falcon rider I have put all information together on internet about the new fanatic boards (for all fanatic riders). The fanatic slalomboard range is completly new and ready to rock! I have seen some prototypes from international teamriders Peter Volwater and Peter de Wit, these boards looked like the 2010 but the whole concept is finetuned. I wonder how much the fanatic ray range is evolved, will it be like the falcon 2010 or 2009 idea??
fanatic falcon 2011
The fanatic speedboard range is also a exciting new development for 2011. The first proto 51cm wide board I saw looks great and will have a hard job to improve older model. So far I saw enough bouyancy and superb upwind angle and good speed. It look likes this new speedboard is ment to be an allround performer.

The 2011 boards
Fanatic Ray 100 LTD 240x61
Fanatic Ray 115 LTD 240x67
Fanatic Ray 130 LTD 235x73
Fanatic Ray 145 LTD 235x81
Fanatic Falcon SL 85 240x58
Fanatic Falcon SL 101 235x63
Fanatic Falcon SL 111 235x69
Fanatic Falcon SL 121 230x75
Fanatic Falcon SL 134 230x82
Fanatic Falcon SL 148 230x85

Tomorrow 15-august-2010 maybe finally the introduction for the 2011 isonics on the starboard site???

Lowwind alpha at Da Curve

Latest session on Da Curve: was again a nice one, a new PB on Alpha. This time I forced myself to use the Severne Reflex 6.2 instead of my favorite sail the reflex 7.0... Only way to do soo was to keep the 7.0 onshore, when we arrived with the boat at Da Curve I had little regret by not taking the 7.0 with me.

Started to rig the Severne Reflex 6.2 on my 4.00m enigma mast. Why the 4.00m??? Because some asked me to test a shorter mast, also I was curious how it would work. For the iSonic 86 I have found good fins and tuning, sooo chose to use the iSonic speed special W49 combined with the Sonntag Fins GPS_2 28cm (rake 17 degrees)

The first attempts to get away didn't work, it was nearly impossible to plane. One lucky gust got me on the downwind course and soo I went 2km downwind. It took a long time and lots of energy to get halfway back upwind. I got again a little gust and did again a speedrun, maxspeed something like 35kn. I was thinking at this moment it would be a long day, too hard to get gliding and 4 fins + other spare parts in my crashvest didn't make it easier to get going on 64 liter. I guess we had wind inbetween 12-18kn. Later a few stronger gusts, and  completly outside the range of conditions the gear worked good. Underpowered it was already fast, I would like to know what damage it does powered up :)

Gear impression:
Severne Reflex sails do work with a shorter mast, 6.2 was tested succesfull. I believe for lowwind a shorter mast might be even a bit better, for gusty/stronger conditions I don't know yet. The 6.2 now looked very nice and I guess the sail stretched and settled good.  The feeling with a shorter mast was even lighter, more responsive, a bit harder for active planning. I have this feeling with shorter mast lightweight speedsurfers could benefit (because they always should take a smaller sailsize)

The Starboard W49 + Sonntag Fins GPS_2 28cm worked like a dream. The first run I felt it, there was absolutely less drag than any other fin I tried before, it feels rather like 23cm long from "drag point of view". Eventhough the fin is made from 35kn till high 50kn it didn't mather I was mostly under the ideal boardspeedrange. After the first fast run I was amazed and decided to stick by the W49, this limited the number of runs I could do, but it didn't matter to me. Just wanted to get as much TOW as possible on my USM gear.

I tried 2 times to do a good alpha, think that big enough gear + slalomfin would add a bit more speed.

Some thoughts:
Next time I should try both the 430 versus the 400 in the 6.2 with new downhaul/outhaul/battentuning.  It might be interesting to test 430 in the 7.0, however I don't know why (because is everything I want with 460).
The starboard W49 should be tested with a shorter GPS_2, now I used the same lenght as the one foot off. Don't feel like shorter is needed for higher speed, but maybe it does give a bit more speed for a reason I don't know yet. I have been surprised before......

5 August 2010 - Amstelmeer windsurfing

We had conditions far above expectation. After driving the day before for nothing to the Amstelmeer this was much better. Sunny and thermal winds giving the best conditions you can imagen, everybody enjoyed the weather (also on the beach). Wad1team members Gauke, Erik Schram, Niek Looze were also present. Too bad the conditions were a bit to gusty for a nice hour. I like the fact more and more people find the Amstelmeer spot.

I am almost done with tuning the iSonic 111 (2010) + Reflex 7.0 combo, as I found Erik Schram his brandnew Sonntag SL-P 40cm perfect. He has exactly the best size for overall performance, soo I will order this one too. Might also a smaller one to make speed near 40kn possible ;). Jurjen vd Noord did once 40kn on his iSonic 111, insane...


Pictures taken by Chris Kluiters, wad1team member (&webmaster) with injury. Hope to see you soon on the water Chris!

[review] Starboard iSonic 86 & 111 (2010)

After having both boards used for more than 5 times each it is time to share my findings. The boards are real slalomboards, even I (as speedsurfer) can seriously feel the difference with gybing compared to speedboards or other boards used before. It actually took a long time to find the board its weak spots, I strong believe there isn't the perfect board for everything. But after testing on different locations/conditions I think to have enough experience for a usefull review.

First findings
The first thing I noticed was the extreme upwind performance, but also high crosswind speed. Not needed to go upwind in strong gusts to keep in control. Also comming from the Fanatic Falcon monoconcave boards it was definitly different, I had to push a bit harder, after a few sessions I learned the trick.

I was a bit affraid these slalomboards had limited speedpotential, especially on flat water. But it was totally different, the boards accelerate great on flat water. On choppy water better take a bigger iSonic to get enough lift to fly over it.

From 111 to 86, is there a serious gap??
Is it possible to jump from 68.5cm wide to 56cm wide? I didn't think it was smart. I wanted to have fun below 15kn soo the iS111 was the compromise. Still there was a board needed that would do 65km/h average as fast as possible, this is exactly what the iSonic 86+ sonntag SL-S 32cm is all about. I am happy it works, actually surprised the iS111 did 66km/h peak with me driving it. It is fun trying to push a big board to high speed, it is definitly more fun for "not-perfect-high-wind-speed-days".

2006 iSonic 105
I owned a 2006 iSonic 105, at that time I had some less sailingskills soo actually hard to compare. One thing I am really sure about, the new ones are still very easy to get going. Space for error, great boards to start, gybe etc.

I use on both boards all the footstraps in the back and masttrack at recommended. For the iSonic 111 the Sonntag Fins SL-S 400 till 430 is favorite, the iSonic 86 I like to sail with the Sonntag Fins SL-S 320 till 330.  One note my biggest sail is 7.0, soo for the iSonic 111 you might find a bigger fin better suited for bigger sails. For select fans I highly recommend the new S10 39cm for the iSonic 111 or the S07 31cm for the iSonic 86. I tested the powerfull select fins and this made me realise for best overall performance the iSonic slalomboards like powerfull fins, yet it is possible to use less powerfull fins (but you need some more fins to suit all conditions).

These starboard iSonic boards have a unique and usefull combination of strenghts and weaknesses. As said before I am a strong believer of strenghts and weaknesses and this is what I am looking for. As long as you remember the weaknesses you can be the fastest man on the water. It simply is hard to beat the iSonic in the sweetspot ;).

Strenghts (compared to other boards):
  • Easy and fast gybing, lots of power!!! Wide or narrow turns both is very good to do
  • Serious speedpotential, no matter what waterstate.
  • Good performance in a wide range of conditions
  • Best upwind angle ever, I am not the only one at our homespot that claimed a 50 degree upwind angle on the 2010 iSonic
  • Superhigh crosswind speed, the first board that allowed me to keep up with speedchamp Peter de Wit at crosswind in medium wind. 
Weaknesses (compared to other boards):
  • Bottom-end in choppy water. Example: iSonic 86 in 15-18kn in choppy water is quite hard to ride fast, while it does on flat water twice the windspeed!!! Solution: Better take a bit bigger iSonic to keep enough lift and power to fly over the chop. 
  • Passive planning, it is possible but the iSonics need more speed before solid planning than long stretched slalomboards. For me I need to pump at least 2 times more before getting in straps and harnasslines. Solution: Again take a bit bigger iSonic to keep enough lift and power to get flying, or learn how to get into planning active (only needed for flatwater).
