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...]


Good prediction, from noon the wind would increase to 25 knots. Started with the Ice 5.3: testing between the FreestyleWave 102 and SingleThruster 99. Sailed the SingleThruster 99 for the first time without thrusters: works very well. Wind increased, time for the Ice 4.7, so no more testing with the 100L boards, but delicious with the FSWF 84, used the K4 Rockets (18/12) under it. Looking for waves to jump and wave. Was a really lovely afternoon, very good wind, unfortunately no sun. [Read...]

After more than 15 years of sailing with DaKine Core Contour footstraps, one is broken, one that I bought used. I have many sets, but this is the only one with cracks. Also the other 2 of the set are still have no signs of cracks. [Read...]

Good wind predicted: 20 to 25 knots, so of to Zeeland. Used the Ice 5.3 al day. Sailed a lot on the JP Single Thruster 99 Pro, tested with different fins. Also used the FreestyleWave 102 to compare. Sail was often a bit big. Weather was delicious, nice and warm and the sun showed itself. Today, the SingleThruster 99 was more fun than the FreestyleWave 102. Was nice to sail together with Martijn and Marvin. [Read...]


Had missed a beautiful sunday afternoon, so took a couple of hours of from work to go today. My 2nd Warp F2010 8.0: Training sail used for the first time. Tested with the iSonic 117 with different fins: Z-Fins 42cm, 44cm and Sonntag SL-X 43cm. Wind was minimal, but with a few pumps I could planing. Not a lot of pressure in the sail, but planing. Clear blue sky, delicious. Little getting used to the curve of the Severne boom. Delicious sailing, 8.0 quite the time not full-power, looking back the 9.0 would have been better. The sun made it a very lovely day. [Read...]


Wind predicted for all the day: 14-18 knots. In the morning, it was already 20-24 knots. So quick to the sea. On arrival wind was gone. All afternoon sailed with the iSonic 127 and Warp 9.0. Tested several fins: Z-Fins 46cm, Select 50cm, Sonntag 48cm and Boss 49cm. Wind fortunately picked up and allowed me to sail. Good light weather test day. [Read...]


Storm wind predicted, good time to make a choice between the AHD Power Wave 253 and the JP Single Thruster 75. Crowded at Kabbelaarsbank. Sailed all day with the Voodoo 3.7, started with the JP FSW 84, soon switched to the AHD Pro Wave 253, then the JP Single Thruster 75. Switched a lot between the AHD and the ST 75, see which board is better in these circumstances. What a day, real summer storm, not cold, and gusts over 45 knots. Especially after the rain was gone it was very good. [Read...]

Ascension day 2019, Sun and wind. Started with the Duke 5.9 on the FSW 102 and MFC 29cm. Soon switched to the Single Thruster 99 to test it. Opted for the MFC 22cm with 12cm K4 Ezzy thrusters. Waveriding is very nice. When the wind decreased took the FSW 102 again, sailed until I could hardly plane anymore. Top day, sun came early, so delicious weather. Pretty fun waves. Could do some good testing of The Single Thruster 99, but need more time to test, the FSW 102 is a really good board. [Read...]


My 7 year old Neil Pryde UXT 48cm is broken, does not lock well anymore. Time for a new one. I am looking for a long 46cm+ extension that is solid and easy to use. That is not so easy in 2019. The Duotone extensions are too short, other brands have other disadvantages. [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...]

Cold Weekend, RegioCup zuid cancelled, some free sailing. iSonic 127 with Warp 9.0 and Z-Fins 46 S--: lots of lift. Then used the Boss 49cm, more familiar. Stance on the board not good. Only in gusts enough to plane. At the end of the afternoon more sun, warmer and wind slightly better. [Read...]

Nico Prien also has a very useful vlog about sail trim. Good summary of the main trim points of the sail. Also interesting for non competition surfers. [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) Together with Rob an afternoon on Kabbelaarsbank hazards. Snuggle up with the Warp 7.0 on the iSonic 101. Different fins tested: SL-P 35/37 cm and 36 cm Venom. In the chop is the Venom 36 cm still favories. [Read...]

(machine translated in 2018) Finally a lot of wind predicted, at last chance to the JP SingleThruster 75 to test properly. Delicious with the Voodoo 3.7 dangers, and who was often even to the small side. Different vin setups tested. Ultimately seemed a longer center fin to work best on the choppy water. [Read...]
