The wind vector on the Garmin it is stuck into the inset or MFD map and the direction is not available as a number except possibly on a subpage somewhere. Vector CA represents the actual wind vector In order to calculate vector CA, we need to calculate the angle at point C. The tangent of an angle is the opposite side divided by the adjacent side. In this case the tangent(angle C)=side BA/side CB= tangent(angle C)= 9/9= 1 Simple reason: if the drag on the hull is low, you can get a significant "head wind" which you add to the actual wind vector to give the apparent wind. This apparent wind needs to be at a "sensible" angle to the boat - enough lateral component that it can still "push" the sail. The lower the drag on the boat, the further downwind this optimum lies.
