Struggled to find the right settings for the Evo V 5.4. At the end of the morning discovered that the harness line on the upwind side was to far back. Unfortunatly that cost me a lot of energy and a fully pumped left arm. After a short break I lacked confidence to push, something didn't feel right. Either the sail does need the 370 mast or it simply doesn't work with the JP 49. Will try it with the JP 45 next time. But can't complain, windsurfing in the Netherlands is a no go at the moment. Overhere we had loads of wind and nice temperatures, what more do you want?! Maybe tomorrow morning another session. But will have to see how I feel. At the moment completely wasted after six days of skiing/ snowboarding and one day speedsurfing.
