Powering of Ships System for Naval Architects and Marine EngineersShip\'s resistance and Propeller calculations for preliminary ship design.SeaPower resistance and power prediction program provide the designer with 28 resistance prediction methods suitable for displacement vessels, planing vessels, and semi-displacement vessels plus model correlation feature and 9 propeller calculation methods. Fuel consumption for a selected range of speeds and selected engine. High-quality editable output is displayed on-screen or printed as text and graphical reports. Reports – Results can be printed from the program directly.

Numeric results are saved in TXT format and graphs in BMP format, and therefore can be modified, resized, and incorporated in any report using any word processing editor.
