calculates the optimum open water efficiency Wageningen B-Screw Series propeller subject to user-specified diameter and cavitation constraints. The nonlinear programming Nelder and Mead Simplex Search method is used with an External Penalty Function. The program will also calculate the operating conditions and efficiency for a specified operating point.
calculates the resistance and hull/propeller interaction of a displacement hull using the regression-based method of Haltrop and Mennon. This uses a modified Hughes Method. An explicit air drag model has been added.
uses (1) methods presented by Clarke et al to assess the course stability, turnability, and controllability by a helmsman, and (2) the regression results of Lyster and Knights to estimate the turning circle characteristics of a displacement vessel.
is an adaptation of the five degree-of- freedom SCORES program to provide estimates of heave, pitch, roll, vertical wave bending moment, horizontal wave bending moment, and hull torsional moment in a random long-crested seaway. It can be used at the parameter stage for initial estimates or, with greater accuracy, after the specific Sectional Area Curve and Design Waterline Curves are available.
