Solid wind for 3.7 sail on wind foil today launching from Locarno.
I was thinking back to the "old days" (I was a bit of a late start). Back then if someone was out on 5.0 (windsurf) this was good guidance. Now, there are so many wind sport versions out there is hard to know. The extreme today was one on 2.5 kite (foil) at the same time as someone else on a 12M (twintip).
