WebThe way to calculate the wind direction given leeway is to think in the frame of reference of both the boat heading and the direction of travel. What we want for calculating the true wind direction is apparent wind measurements from the standpoint of the boats direction of travel. We then use vector math to find the true wind direction. black and neon green t shirt
