This document reviews the existing state of practice in the computation of leeway drift. Five documents were specified for review. One document was found to be unavailable. All four remaining documents used essentially the same governing equations for the body motion. These equations are well known and widely used. After definition of terms, the generalized analysis of the force balance of a drifting object in the open ocean is presented. Comparisons of the generalized presentation with two of the referenced papers are made to show the parallelism of approach. An idealized measurement program is defined to parallel the theoretical formulation. A set of sensitivity analyses to test the relative contribution of the various terms and parameters in the model analysis is presented. Recommendations for future work, both in the laboratory and the field, are presented. |
