This article describes studies that evaluate the accuracy of measuring a ship’s heeling angle with an
inclinometer. It does so by comparing inclinometer readings with benchmark measurements made with the
optical method. The first part of the article describes the measurement station used for gathering measurement
data. This station included an inclinometer and a CCD camera, and was used to process digital images
incorporating a horizon line to indicate the ship’s heeling angle. The second part of the article describes the
data gathering process carried out on a ship at sea. The final part describes a statistical analysis which
compares the angular measurements based on an inclinometer with simultaneous optical benchmark
measurements.
