YES! I record how far we have gone each day, or for segments of the voyage, and then calculate average speeds. I look constantly at data from the boat, like boatspeed and windspeed, and the angles (geometry) of the wind and the boat. In navigation also I look a angles of when to tack or gybe. Math is used extensively in the design and engineering and building of the boat, and also in sailing her.
