Yesterday we did our first sail this year and that was not bad, the hum we did have above 14kn were gone. The tuning of the daggerboard has helped to solve this. I only have to calibrate the windsensor but that I do coming Thursday. The sensor was dismantled and the wind angle over both sides is not the same.
This is not difficult, sailing on the wind on both tracks and make the angle the same with two buttons on the windsensor interface.
On the end we looked on the max speed we did and that was not bad 17,7 kn in max 20 kn wind with only jib and main.
Coming weekend we have our first race of the season https://50mijl.nl/
