New Speed Fin Releases

Today I heard about 3 speed fins going into production. This got to be a new achievement, a milestone for speedsurfing. Again prove speedsurfing is alive and back.

GPS_4
GPS_5
The Sonntag Fins GPS_4 is the speedfin with conventional outline, the main thing we tested for was a good performance and safety/grip. The GPS_4 can be tweaked both in rake and lay-up from a flat water water powerhouse up to a chaotic off-/onshore grippy and safe fin. The Sonntag Fins GPS_5 is a new widebase design, made to make windsurfing possible in extreme shallow flat water. The GPS_5 has a wide range of working angle of attack, in other words its not needed to be the best most fit windsurfer in the world to handle this widebase. Read More about Sonntag Fins



Type X
The 3th new speedfin release is a complet new concept. From Black Project Fins. The Type X. Widebase AND asymmetrical, this is new.
But there is more, you don't order a type X in lenght! No you can order for the speed you aim for. A fin for 40kn, 45kn or 50kn. Both for starboard and port tack. Read More about the Black Project Type X

Very Deep Deck Concave

For 2011 we saw Starboard and some others lowering the mastfoot towards the waterline. Most extreme example at this moment is the Starboard iSonic. After a couple of months sailing the iSonic 107 its time to evaluate...

Upgrades 107 vs 111
Upgrades: very deep deck concave, harder rails/more square rails under backfoot, slightly more V (overall).

First the extra V and harder rails. The board has a little extra freedom over lenght axle also less drag at the tail thanks to this extra bit of V. The harder rails are easy noticed, and thicker tail, clearly the board can be used now with some more tailpressure.

The Very Deep Deck Concave, first times sailing on the iS107 board the improvement was not really clear. Lateron I tested the iSonic 107 in 30kn gusts (and even more a bit later), NOW it was finally clear. In highwind for (each) iSonic the board has been improved (and this probably doesn't come from xtra V& harder rails). The board has become more neutral trimmed in overpowered conditions, nose doesn't go upward as easy in the gusts. Especially when making a lot of airtime in choppy conditions it helps, and makes windsurfing fast easier

Also I have this feeling the very deep deck concave prevents rolling over the lenght axle a bit, because afterwards looking to the board shape I was amazed not to notice the extra V on  (only the good things that come with more V= speed)

Conclusion Very Deep Deck Concave

  • Board becomes more stable in the air in highwind flows
  • Rolling over lenght axle reduces a little bit

Speedsurfing with Freeracestuff – Part1

I started Speedsurfing with a mix of Freemove- and Slalomstuff and orientated my quiver more and more to Slalom- and Speedsurfing. For a lot people who like to go fast and thinking about starting Speedsurfing it is a tough question if it makes sense to buy pure Slalommaterial or to start with something like Freeraceboards and -sails. Especially during the last few years some brands introduced Freeracematerial which should be nearly as fast as pure Slalomstuff, but easier to handle.
I have checked the GP3S database and tried to analyze the potential of this Freeracestuff. Okay you get much more information about Slalomboards and -sails, but in my opinion there was enough information to get a trend. The first part of the article contains my results and in the second one I will tell something about possible reasons.

The usual (slalom) iSonic
+ fullrace sail
Let's start with the easier chapter, the sails. Are Freeracesails only the little brothers of full Racesails? Okay, no Freeracesail reached 50knots until now, but most notably the Neilpryde RS:Slalom, Northsails Ram and Severne Overdrive scored a lot of sessions with 40knots+ averages. 40knots+ average is a really fast session for nearly everyone and the best sessions with these sails are around 42,5knots which mean you are close to the top 50 in the GP3S Overallranking. In my opinion there are definitely competitive Freeracesails on the market!


To analyze the potential of the Freeraceboards is much more difficult, because you have to consider that more sessions were done with Slalomboards and furthermore the trend is not as clear at it is with the Freeracesails. Obviously you have to compare the Freeraceboards with the Slalomboards and not with the smaller Speedboards on which most of the highspeeds were done.
VERSUS (freerace) Futura 93
+ fullrace sail 
I have heard the rumor that the Starboard Futura is maybe faster than the iSonic. Well, the GP3S database doesn't really confirm this all up, but average speeds around 36,5knots done on a Futura 93 demonstrate the potential of this board. The best speeds on iSonics with the same width are around 38,5knots and on JP Slaloms or Fanatic Falcons even faster speeds were set, up to 40knots. It is hard to evaluate this speeds because, as I said, more sessions were done on Slalomboards, but in my opinion 2knots or more are a bit too much to say the Futura has the same potential as the iSonic or another pure Slalomboard, on the other hand 36,5knots is really fast and with a bit more comfort the Futura is definitely an option. Beside the Starboard Futura the JP SuperSport/Cross 96 had also great results with speeds around 36,5knots average.
Viewing the next two sizes verifies this impression. With a margin of around 2knots+ the Slalomboards stay ahead of the Freeraceboards. Moreover the treatment of the real big boards is very interesting, now the advantage of the Slalomboards decrease notedly. Many Freeraceboards like Starboard Futura 122/133, JP Supersport 74 or Fanatic Ray 125 scored really good results. As a matter of fact the fastest session on a Futura 122 was 34,36knots and therefore it is slightly faster than the one on an iSonic 122 which was 34,29knots...

All in all many Freeraceboards have a good potential for going fast even though the pure Slalomboards seem to be a bit faster, especially the smaller sizes. For starting Speedsurfing some Freeraceboards are an intersting option, you get some comfort like more volume and you can go really fast. Maybe you can beat your friend on his Slalomstuff :)

YEAH you can have fun in 13kn gusts with GPS

Thanks Marjon van Leeuwen and Raymond Wortel for this beautiful shot!
Saturday 2 April 2011, I went windsurfing with my brother Wouter. He could decide where to go and we went to the Gouwzee, because Wouter wanted to test his 96cm wide board for lightwind. The Gouwzee is a perfect spot for having a good time, many good windsurfers, nice water and a little bit less wind compared to the Amstelmeer.

I rigged my brandnew Severne ReflexII 7.8, and used both the iSonic 107 and 127 with Sonntag SL-P fins. On the picture I ride Erik Schram his iSonic 127, what a great ride, what a joy! Another one on my list "what to buy" when I win the lotery ;). Thanks Erik for letting me try 85cm wide iSonic 127!

Yeah lightwind is fun too, waiting for a gust and go with the flow. And during/between windsurfing in the sun getting a tan, or talking with friends. Only 14 minutes above 20kn boardspeed, GPS topspeed below 30kn, it all doesn't matter when you're having fun together with other friendly windsurfers. Still fun and challenging to see if you can double the windspeed :)

German Speedchannel!!

German speedchannel in the making
Finally the channel will be ready this season, a topsecret project for many years. Dimensions 2100m long and 150m wide, curved course. It will be great to have a speedspot without tidal problem and free to use. Manfred Merle and Thomas Doublin claim the record will be back this year.
