Description

Formula windsurfing aims at top performance from 8 to 20+ knots upwind and downwind. The board is 100 cm wide, 230 cm long, the fin is 70 cm long, and the sail is about 11 sq.meter.

Apparent wind analysis

Upwind

Downwind

The apparent wind is of course very front oriented. Its speed ranges from 27 to 29 knots, with a 18 real wind.

As you can see here, the apparent wind speed can be lower than real wind (16 knots compared to 18), and moreover to board's speed (about 22 knots): less wind in your face than if your was standing on beach!

Another important point here with windsurfing is that apparent wind always comes in front of you, even when going downwind. The apparent direction is somehow comparable to the one of upwind course, but with less power in the sail.

The Apparent wind direction changes radically from one tack to the other (much more than on the upwind example)
