Calibrating to Ensure Data Accuracy
The accuracy of the data generated by your instruments and performance evaluation systems depends on accurate calibration. While the following subsection presents an introductory explanation of instrument calibration, you must refer to the manuals that came with your instrumentation systems for the specific calibration procedures.
The subsections that follow explain the calibration methodologies for the following variables:
∙Boat speed
∙Compass
∙Apparent wind angle
∙True wind angle
∙True wind speed
Boat Speed Calibration
Boat speed calibrations are entered directly into your instrumentation system (refer to your system’s manual for the procedure). While it may not be practical to check boat speed calibration on a daily basis, we encourage you to check this variable on a measured mile as often as possible, as the
