Hydrostatics and Equilibrium Characteristics Computer Program for Recreational Boats.

摘要

This report is intended to serve as complete documentation of a versatile computer program which calculates hydrostatics and equilibrium characteristics. It differs from other hydrostatics programs in its applicability to odd-shaped boats and in its capability of performing equilibrium calculations. The integration scheme uses trapezoidal rule throughout, allowing random spacing of points and stations defining the hull form. This allows almost every type of hull form to be represented and computations performed. The equilibrium characteristics feature allows determination of transverse and longitudinal righting moment curves, heave restoring forces, trim vs. heel angle coupling, etc. It also is possible to determine the draft, trim and heel for any loading condition Included in the report are a program explanation, user guide, program listings, program flow charts, and a sample run.
