The blades on a wind turbine spin according to the speed of the wind.

Ac75 max wind speed. Crucially at the lower end of the scale they are now capable of travelling three or four times the speed of the wind making for exciting in racing in light airs. Their only criticism is. Topping the 50-knot barrier used to be the.

Maximum Daily Mean Wind Speed kmh Since 1984 for Climate Station. Min wind 6 knots max 24. That will be fun if wind is at minimum.

These 75-foot foiling monohulls are now travelling at three or four times the speed of the wind regularly breaking the 50 knots mark and 100 kmh 54 knots looks possible. I guess theyll do the same this series.
