Windsurf season 2017 – 2nd half – new stuff

The 2nd half of this 2017 windsurf season the opportunities to go windsurfing where less than I wanted. So the moments to remember are extra special. πŸ™‚

I enjoyed our family holiday in North Wales. What a spectacular landscape and coastline it has!

This year again I had a few good raceboard sessions. The combo of the good old Fanatic Cat 380 with the new Warp F2017 9.6 is working out great. The reduced luff curve and less loose leech gives the sail good lift needed for railing on the daggerboard with tight upwind courses.

We also had the introduction of new 2018 surfstuff at Telstar Surfclub. A lot to see for next season with some good inside info from Jordy Vonk and Herman van den Berg.

Some snippets:

  • Falcon TE 98, new shape
  • Blast, now with tuttle box
  • Gecko foil edition
  • Biggest sizes Falcon/Blast foil approved
  • Freewave STB
  • New footstraps, more comfort, with sizeindicator
  • Super Session, new freewave sail in the range
  • Warp f2018 proto, evolution from extensive R&D, colors/graphics will be different
  • All sails new symmetric battenpockets and come pre-tensioned specific per sail/batten

I changed from the two big slalomboards (129/159) to one, the Fanatic Falcon 136 85cm wide. My experience was that with my weight (78kg) haveing two lightwind slalomboards didn't have enough advantage. That's why I'm back to one big lightwind slalomboard and the 136 is a winner!

For the fins I now have a new F-HOT RS3 45cm to try. This fin will be the most used with the Falcon 136 and Warp 8.4.

Just in. the North Sails Warp F2018 8.4, rigth out of the bag, prΓ©-tuned battens, just rig and go! Smooth camber rotation. Check the movie on my Instragram account.

Very motivated for next season, hope the winter is short!

Windfoil is coming!

Exciting times, Fanatic is launching a windfoil and I will be one of the first to try it! πŸ™‚

I'm very curious about the learning curve and lightwind performance compared to Lightwind Slalom and Formula. Will feel like an absolute beginner again πŸ˜‰

The Fanatic windfoil will have a alu mast and carbon wings. Info about he Fanatic windfoil will follow soon. Also there will be Fanatic boards "foil approved" with reinforced tuttlebox and nose.

Here's a productvideo of the Gecko foil edition with a sneak peak of the windfoil in it.

Track your progress and keep improving!

Windsurfing is great and motivating to try to improve yourself every time!

To keep track of my progress I have been using a GPS device for my slalom/speed sessions since 2008 when I started windsurfing again. The website offers the possibility to record your sessions including the equipment used. I have 199 recorded sessions sofar and hope to add a lot more in the coming years!

Last weekend I decided to go windsurfing with a lot of surfmates on the Veluwemeer. This spot is called Polsmaten and with the predicted wind ideal for a nice Slalom session. 

We arrived early and with the predicted wind I rigged my Warp 7.7 with the Falcon 114 and F-HOT 38cm fin. On the water the wind was on/off but the gusts kept getting stronger. With a few changes in settings, mastrack 0,5cm back and more outhaul, the Falcon just flew over the small chop with a lot of control and good speed. In the meantime a lot of riders where already using 90ltrs/7.0 sets, but I stayed 3 hours on the water with the same Slalomset because of I wanted to get most out of it.

This session resulted in a Personal Best for this medium size Slalomset:

  • 10 sec run 33,1 knots
  • 500 m 31,5 knots

Fastest for me since 2008 with slalomboards >68cm and sails >7.6!

I'm very happy with this improvement and this motivates me for the next sessions!

Thanks for reading! See you next time, Mark.

March windsurf sessions – spring is in the air!

Last month has been up and down with the weather in the Netherlands. Spring is starting but difficult to get the right windsurfing conditions in combonation with time available. I did have time to do some fin testing for the Falcon Lightwind and spend time windsurfing with my daugther!

Lightwind Fin testing

Sunny, windy, surfmates, top! 

A bit time for (Falcon 159) Lightwind Slalom fintesting! F-HOT S3 48, Choco Black Pearl 50, Gasoil 6/3 52, Select S1 57. What fin would be best for mini-formula, combi Warp 9.6. At my homespot Kraaijenbergse Plassen.

Used the Falcon 159 LW and Warp F2017 9.6.

Need more time/trimming with this combo to get more speed, not satisfied yet (max2sec 25,4 knots). Motivated!

Lightwind Slalomfin testresult:

  • Select S1 57cm to stiff, no lift, difficult to rail, sail free and push against.
  • Choco Blackpearl 50cm, very good allround fin for this board with 9.0 and smaller
  • F-HOT 48 cm, to small for this board
  • F-HOT 54cm perfect, good lift and control, good railing, easy! Thx for trying Peter! Have to order one πŸ˜‰ 

/update: ordered a F-HOT 60cm lightwind slalomfin "special" made by Steve

Weed Speed Race

Since 2013 we are organizing the Weed Speed Race event. This is a virtual speed event where you can post sessions on The spot is "Strand Horst", a well known speedspot in the middle of the Netherlands. My part in that is "ranking master", I developed the software for the dailly/yearly ranking. End of march we had the pricegiving ceremony at Telstar Surfclub with some nice prices from our sponsors. πŸ™‚

Windsurfsessions winter 2017

It's still winter in the Netherlands but I had a few very nice windsurfsessions last weeks.

Luckily for me Sipke Bijlsma made was there to shoot some picures, thanks!

Equipment I used in these sessions.

  • Fanatic Falcon 159 LW with the North Sails Warp F2017 9.0 and Choco Fireblade 50cm
  • Fanatic Falcon 129 TE with the North Sais Warp F2017 8.4 and F-HOT 42cm

My fitness is better than before, now with enough breath and strength and having FUN!

Findings from these sessions below.

Falcon 159 / Warp 9.0

Conditions: gusty wind 8-16 knots, inland lake, windchop.
+ early planing, passive just go a bit broad, active on the same course
+ good tracking course, no luff/lee steering
+ surprisingly good gybing (in/out) and keeping speed in the gybe
+ very good speed and keep going in luls, compared to surfmates
- a lot of pressure on my back leg, no time to change settings yet
- because it was choppy not enough lift, railing was diffucult, next time try a different fin

Falcon 129 /  Warp 8.4

Conditons: wind 16-25 knots, inland lake, windchop.
+ with my slalom setup easy to sail with a lot of control, board and sail!
+ with this big slalomset no problem with the chop and wind gusts
+ the Falcon 129 (80cm wide) does not need a big fin
- for more speed I need to change mastfoot/boom positions

See you next time, Mark.

Why I’m happy with my F-HOT Slalom fins

Since 2013 I've been using F-HOT Slalom fins. I was one of the early adopters and still happy with these top fins!

In that year I compared them to several other Salom fins after I have been using the Choco Fireblades for several years. I wrote my review on fins some time ago.

Based on that review I choose F-HOT. I now have them in several sizes, type S3, 36-48cm. I use them with my Fanatic Falcons. For the biggest board (130/138) my most used fin is the S3 46cm with the North Warp 9.0 combo.

What I really like is the light and free feeling these fins give my boards. You can put pressure on them early and after that they give an even and constant lift when accelerating, with good control. That gives confidence, never strange or unexpected moves from the fins. You can focus on other things. πŸ™‚

Ross Williams uses the F-HOT RS series that have been developed after the S series. More focussed on PWA conditions, downwind course, fully powered at the limit. What I hear is that the RS is more technical to sail but faster when you can handle them.

With my weight (78kg/184cm) I use my set most often in well powered conditions, not on the high-end. The performance that the fins give me is more dependant on me than the fins. I feel that I did not get the max out of the fins yet and I expect more is possible. Also the support on the fins that Steve Cook gives is also remarkable, a real craftsman. I crashed one of my fins and Steve repaired this fin as new!

Please let me know if you have questions or need advice on what fin type/size for your set. Happy to help you.

See you next time, Mark

Windsurfblog update: new layout, personal goals, quiver review and tuning tips!

A fresh start of 2017 with a new layout of! 

For 2017 I'm planning to give more frequent blog updates. Please let me know what you think of the new layout and specific subjects or questions that you want me to blog about.

Personal goals

My goals for this windsurf season is simple, get fit again so I can get more time on the water and choose the best quiver for this purpose.

Because of my rheumatism medication I have anemia and it's difficult to keep my fitness on level. End of last year I started with the supplement Floradix, a liquid iron elixer. Last month I started with a basic (indoor) workout program, 2x per week, 2 hrs, 13 exercises with focus on endurance, flexibility Γ‘nd strength. The first results are very positive. I can see that my fitness improves every week! Also the daily walks with our dog Didi are much easier and longer than before, a win-win. πŸ™‚

But the best therapy for me is of course go Windsurfing! πŸ™‚ 

Windsurf quiver review

I changed my quiver for this windsurfseason to maximise the range of use, conditions and fun! Last season the Falcon 138 (85cm) and Warp F2016 9.0 was the most used Slalom combo for me. Because my homespot Kraaijenbergse Plassen is a small lake the wind is always gusty and fluky, you need a big set. This year I decided to go for the new Fanatic Falcon 159 Lightwind (90cm) wide and replace the Falcon 138 with the Falcon 129 (80cm). Also I added the biggest North Sails Warp F2017 9.6 to use with the Lightwind. Combined with the Falcon 114 (71cm) this should cover my Slalom needs.

When the conditions get rough I don't have the physics to hold down a full-on slalomboard. So I decided to change my highwind Falcon slalomboard for a new Fanatic Blast 100 (62cm). This new stubby syle board is called a performance freeride and looks just what I need for blasting around. For this board I added the S_Type SL 6.0, 6.6 (3 cam sail), a bit easier to handle than the full-on Warps.

The Slalom fins I use for a few seasons now are F-HOT Slalom S3. These carbon fins fit my style, they give good lift and performance with ease of control! The Blast has standard a powerbox Choco 34cm fin that I still have to try.
Falcon 159 LW, Warp 9.6, 9.0, 8.4
Falcon 129, Warp 8.4, 9.0, 7.7
Falcon 114, Warp 7.7, 8.4, 6.6
Freeride (performance)
Blast 100, S_Type SL 6.0, 6.6
For my other quiver (speed, wave, raceboard) see further below in this article.

Fanatic Falcon 159 LW (Lightwind)

I have used the Falcon Lightwind several times together with the Warp 9.6. 

Remarkably good / fine trim, you can give full pressure and with every gust the board accelerates with control, the nose remains low. It jumps onto a plane easily and is very fast at all courses in comparison with my surfing buddies at 85cm slalom and formula boards. i used it with the standard included Choco 50, as well as with Select S1 57 but this was less loose.

A very special board!

My impression is that this Falcon Lightwind does not need a super large fin to sail very loose. This I believe has to do with the other cutouts compared to the 152.  

Specs: 90x230cm, 159ltr, full biax glass fibre / full PVC Sandwich, 8.5kg

Fanatic Falcon TE 129

I used the Falcon 129 at the RealTrip event in very light winds with the Warp 9.6 and F-HOT 46cm fin. The board can handle big sails/fins but this was just too big. Next time I will use the Warp 8.0 and F-HOT 44cm. I expect that there will be just enough overlap between the Falcon 129 and 159 to switch easy. For example when the 9.6 with 159 is on it's highend, I can switch to the 9.0 or 8.4 with the 129. Al depending on the waterconditions of course. When it's flat the combo big sail with a small board is faster, but when it's choppy a wide board has an advantage.

The same goes for the switch to the Falcon 114 (71cm), when the 8.4 with 129 get to big I can switch to the 114 with the 7.7 or 8.4.

Specs: 80x230cm, 129ltr, full biax carbon sandwich, 6.9kg

Fanatic Blast LTD 100 

I haven't used the Blast with the S_Type yet, but the combo look promising. The shape of the Blast is stubby like and should feel compact on the water. The bottomshape is a light concave V-bottom for good control, speed and easy gybing. 

Performance freeride Fanatic Blast LTD 100 with the North Sails S_Type SL 6.6/6.0.

Specs: 62x231cm, 100ltr, full biax glass fibre / full PVC Sandwich, 6.3kg

North Sails S_Type SL

The S_Type has a very nice profile and feels very light. Both 6.0 and 6.6 fit on the same 430 mast.

North Sail Warp F2017

Evolution of the succesful Warp F2016, some small changes that I can spot sofar like mastsleeve reinforcements.

I used the North Sails Warp F2017 9.6 with the Fanatic Falcon 159 LW. Third time with the 9.6, getting dialed in with the trim. Ideal with these low wind conditions. The Warp feels a bit softer and better to pump, yet stable in the gusts. Very happy with that.

Tuning- and trimtips Warp F2017

Cams: The Warps are provided with cams pacers, factory fitted. I pull it off and go out sailing a few times with a sail. The sail must "set" itself first. Then look for the right camberpressure. The camber just below the boom (cross batten) you need to press just to leeward. The cam just above the boom needs to press easier. The upper cam even easier. The lower cam is usually the tightest but would like to have a little less than the cam under the boom.

Note that this is different from battentension.

Tension battens, cross batten the tightest, that is turning with two fingers, do not overdo it. The lower and 3rd bar slightly less. All other battens no tension, just that the batten does not have to many wrinkles.

Wrinkels in the sleeve are not a problem! Please look at this on the water when there is pressure in the sail, not on shore or in the garden. πŸ˜‰

For example, look at this picture from Laurence Carey who's traning on Tenerife right now.

Downhaul: I use my sails never super overpowered. Ideal for me downhaul 1 cm from the maxtrim sticker in the upper part o fthe sail. Never mind the exact dimensions, trimming purely on the sticker in the sail!

Outhaul: use vario! Sailing is super with only trimming the outhaul. No weird feeling with flat or full trimmed, the sail stays in balance.

Rigging I do in this order: downhaul to 10cm from below, put on first the boom with good outhaul. Then put on the cams, first the cam under the boom, then the lower and above the boom, the upper cam goes on itself when putting on more downhaul. Please note that you only push on the cams itself and not on the mast sleeve. Then apply the appropiate downhaul tension. De-rigging is in exactly the reverse order.

My other windsurf quiver

For Speed I will stick to my favorite Falcon 85 (58cm). With this board I got my personal record of 40 knots max and I first want to breack that personal record before changing this board.

Cruizing and making long trips in lightwind is also what I like to do with the Fanatic Cat 380 raceboard and a big oldskool ART 10.0 racesail. I also use this board for SUPing. Ideal when it's glassy and sunny.

For Wave (bump&jump) I use my 30year old custommade Kosmos board, still going strong. This picture is taken at Makkum, IJsselmeer.

Falcon 85, Warp 5.7
Wave (bump&jump)
Kosmos 85, Curve 4.7
Cat 380, ART 10.0

Now it's time to get back on the water again and have some fun! πŸ˜‰
