    1. Scope

    Military and municipal small craft builders and buyers generally have to determine the centers of gravity for their craft in order to apply stability criteria. The conventional in-water stability test can be difficult to perform accurately on small craft, so in-air inclining experiments are often specified. However, there are no guidelines available to help standardize and explain the process. This guide serves to provide the marine industry with an understanding how to conduct an Air-Incline stability test for any small craft. It contains procedures to ensure that valid results are obtained with precision at a minimal cost to owners, shipyards and the government. The guide is not intended to direct a person in the actual calculations of the lightcraft weight and centers of gravity, but somewhat be a guide to the necessary recommended procedures followed to gather accurate data for use in the calculation of the lightcraft characteristics. A complete understanding of proper procedures to conduct a stability test is paramount to confirm the results gathered during the test can be examined for accuracy. This guide is recommended to be used for all small craft.
