Wind WNW and clear skies: perfect for the Grevelingendam. Sailed with the Banzai 6.0 and ith JP FSW 102. Tested inboard and outboard strap positions. Inboard clearly nicer for jumping and waveriding. Outboard feels more freeride: faster and more natural feel. It was wonderfully sunny. With 10 degrees not very cold, but wind still felt chilly. [Read...]


The whole afternoon a lot of rain predicted. Before the rain sailed with the iSonic 117, S-Type SL 8.3 and Busca 46cm. Lots of variation in the wind, happy with the variable outhaul. Sailed untill the showers came. In the evening, after the showers went to go surfing again: iSonic 117 with S-Type SL 8.3 and Sonntag SL-P 44cm. Nice sailing until the wind died. Several 490 masts tested. [Read...]


Went sailing with the slalom competition guys at Oostvoornse Meer. Wind direction NNE, which is not at all favourable. Used iSonic 127 with Warp 9.0 and Z-Fins 46cm. Used a Power XT 2.0 for the first time: impressed. Wind was extremely gusty and turned a lot. Not a very nice session. Worked on the trim of the 9.0 a bit. Not really nice sailing, but instructive.

A few years back, Pieter Bijl has made a very good video about camber and batten tension tuning. What is the correct tension, how do you adjust it to etc. Useful for everyone who is sailing with cambersails. [Read...]

For years, there has hardly been any innovation on extensions. The North Power XT exists since 2004. Now there is the NoerStick, really a new concept for an extensions. [Read...]

Slalom training. Wind less then expected, sailed with the iSonic 127 and Warp 9.0. Tested different fins: Sonntag SL-P 46, 48cm and Busca 46cm. Usefull but cold afternoon, the SL-P 48 cm seems too big. Should spend some time to find a better trim need more pressure on my front foot. [Read...]


(machine translated in 2018) Asked about Zeeland, wind especially in the morning, on arrival no wind. Started with 6.6, which was quick to great. 4.7 on the FSW 84 get caught, first with thrusters, later single fin. To the wind decreased, the 6.6 again getting caught. The getrimmed and very good 6.6 practiced a lot on jibes views, that quickly went very well. Fun and fun day with my buddies. I enjoyed, was cozy, and also much in the afternoon sun. [Read...]


(machine translated in 2018) Wind was a lot less than predicted, ideal for the 9.0 LW to trimming. First time with my new Severne Enigma boom. Board was the iSonic 127 with Boss 49 cm. Good trim, wind went from a minimum to a maximum of 9.0 for the LW. The iSonic seems leak under the foot band. Informative/useful day. [Read...]


(machine translated in 2018) Delicious afternoon at sea hazards. The whole afternoon with JPW Freestyle Wave and Ice hazards, together with Martijn 5.3 84 different vin setups tested. The 5.3 was quite the afternoon on the large side. I is becoming more joyful of my FSW 84 Pro which Thrusters give me even more tuning possibilities and that is where the range is even greater.

(machine translated in 2018) Prediction: this morning was still wind, to hour or 1, then quickly decreasing. So I was early in Zeeland. Only a single surfer at Kabbelaarsbank. Few hours tested many different fin configurations under JP FSW 84 Pro 4.7 with the Ice. I start to feel reasonably at which fins good and which work less. Which fins for which and when work well. Very happy with the extra options under the JP FSW 84 Pro. It was delicious sunny. [Read...]


(machine translated in 2018) Wind forecast took towards the weekend, but there was still 12 a 16 knots predicted. Delicious the time taken to Daytona 9.0 on the Epic 520 cm mast to trim and to try different fins. 47 cm Boss is on the small side, the C3 D2 52 cm and Select 50 cm seem very good, very different and both are not too large. Weather was great, nice and warm and fine breeze to have a good trim for the 9.0. [Read...]

(machine translated in 2018) After more than 4 months, the come, there is again surfed. 7.3 spirit of my father used on my iSonic 117. Resignation and planing, jibes: by geplaneerd. Proud of myself! Slats of the Spirit trimmed. Kauila v2 is delightful as your back is painful: recommended. Nice to be back again. [Read...]

(machine translated in 2018) Sonntag produces high quality Finnish, each fin has some numbers on the base, for example: BS75FT33% on SL-P me 35 cm. But what does that mean? Bs = Bending Stiffness, FT = Flex Tip. Okay, but what does that mean? [Read...]
