Apparently this is what the car feels.

Ac75 apparent wind. There is only 4 degrees difference to the apparent wind from going on the wind to running as deep as you can. Thats apparent wind - its what your hand feels out of the window and on a boat its what the sails feel. The virtual reality goggles and lack of any apparent wind spray or noise make for a surreal experience.

But once the boat is foiling the apparent wind speed and angle will change dramatically. As the car speeds up the wind increases in velocity and the direction of origin feels like it moves forward. Throughout the race the teams will constantly adapt their sail plan up and down the apparent wind range.

AC75 Class Rule 1210 Proposed amendment. The AC75 is a completely new class and two years ago. The wind that the car feels is the shifted wind called the apparent wind.

As with the AC72 the vexed issue with the Code Zero is that in displacement mode the Extra is required in marginal conditions to get the AC75 up to foiling speed but once the AC75 is up and foiling the sail is an impediment as the apparent wind comes forward very quickly. The variance in strength and direction raises the issue of why race organisers are even bothering with the potential TV stopping tidal flow complication - given that the AC75s are sailing in an apparent wind of up to 60kts and a knot or so of tidal effect on the race boats is going to be negligible. At the speeds reached by the AC75 we are talking about 50 knots the apparent wind is such that the sailboat is upwind with a beam wind.

The fifth yacht planned from the American Stars Stripes challenge has not yet been built and already the challengers and the defender are working on their second yacht which should be launched next summer for the first ones. The boat feels the new wind generated by its own speed. The AC75s are able to lift out of the water and fly in just six knots of wind.

Im sure weve all experienced situations when our mainsail trimmer didnt react to a movement of the helm. Click and drag on the slider bar. In mere seconds the AC75 goes from low-speed displacement sailing in as little as 10 knots apparent wind speed to high-speed foiling in excess of 50 knots apparent wind speed.
