Abstract
A device and apparatus for determining wind conditions around a sailboat. The device includes means for receiving a measured wind angle and wind speed readings from a wind sensor attached to the sailboat and readings of boat heading and boat speed through the water, means for storing wind angle correction data, a computing unit for computing a corrected wind angle reading using the measured wind angle reading, the boat speed reading and the wind angle correction data and for computing a wind direction using the corrected wind angle reading and the boat heading reading, and means for displaying the wind direction. The device additionally includes input means for receiving a wind direction error tack to tack, means for determining the current tack state of the sailboat using the measured wind angle reading, and means for modifying the correction data. Thus, powerful and intuitive correction of wind direction readings is possible.
