Inverted Y Foil Version 4.00


After the foil test Idefix VII went for a regular sail with standart and Mach 2 foils. However the forestay snapped resulting in dismasting, luckely with no other damage. The set of stays was out of PBO, will not be using that again. Going back to regular stainless steel. The load on the forestay is quite high.

Yesterday Idefix VII got fitted with inverted Y foil Version 4.00. Conditions were: 010900Z 330/12 46/09 995. Geometry: rectangular: 2 x 8mm x 70cm x 12cm, 40Deg x 4Deg. Fixation: 12 layers of carbon, 6 and 2 M8 screws. Aoa set arround 6 Deg. Max speed reached was 5.5 Knots and did not get foiling. Drag to high and not enough angle of attack.

Inverted Y foil gets foilborn, version 3B



Today here in Abu Dhabi, winds at 330/12, 40C, QNH <1000 allowed to get foilborn on steel inverted Y foils. Idefix VII did not foil for long as ventilation caused total lost of lift resulting in bow dive.

Rich Miller was the first to come with the concept of inverted Y bow foil which he tested very successfully on a windsurfer in California. Further information can be found under: www.foils.org/miller.htm

Foil improvement is again at the order of the day, the concept looks feasable.
