Resistance and Powering Prediction Program

Autopower's advanced user interface enables optimization of hull parameters based upon twelve independent resistance and propulsion methods for displacement, semi-displacement, planing hulls, and catamarans.


Autopower Key Features:

  • 8 methods for displacement hulls
  • 1 method for semi-displacement hulls
  • 2 methods for planing hulls
  • 1 method for catamarans
  • Propeller optimization
  • Methods based on empirical studies and approved tank methods
  • Analysis of 5 models concurrently
  • Hull parameters may be generated by Autoship
  • Can be called from Autoship
  • Editable graphic and tabular reports
  • Rapid calculations and output
  • Built-in Report Editor. Save reports to MS Excel
  • Graphics can be resized or repositioned within report


Autopower resistance and power prediction program provides the designer with twelve resistance prediction methods suitable for displacement vessels, planing vessels, semi-displacement vessels and catamarans. High quality editable output is displayed on-screen or printed as tabular and graphical reports.

Graphic User Interface

Up to five different hull alternatives can be considered simultaneously, facilitating comparative design studies and optimization. Parameters may be easily changed for quick recalculations. Limits of each resistance prediction method are clearly displayed, providing guidance on the selection of the most suitable methods. Using Windows, Autopower may be one of several programs running at once - a significant time and frustration saver when the effect of a change to the model is to be examined.

Fast Link to Autoship

Autopower has a fast link which enables hull parameters to be imported from Autoship. Hull parameters may also be easily specified by the user.

Export to Word Processing Programs

Edit reports off-line using either the built-in Autoship Report Editor, or export to MS Excel.

Displacement Methods

Andersen & Guldhammer, Holtrop, Fung, van Oortmerssen, Digernes & Cheng, Jin, Su & Tan, Calisal and FAO (UN).

Planing Methods

Savitsky and Radojcic.

Semi-Displacement Method


Catamaran Method


Propulsion Efficiencies

User-specified or calculated according to Wageningen B-series or Gawn-Burrill KCA series polynomials.

Propeller Optimization

Propeller optimization can be carried out in two modes: for fixed propeller diameter and ship speed or for given delivered power and propeller rpm.

Hardware required: For optimum performance we recommend a fast Pentium with 16 MB of RAM, 10 MB free disk space, 1 MB graphics card and an SVGA monitor.
