Easy Data Input
The RhinoMarine Planing Analysis is flexible, allowing almost any type of units to be used. Calculations can be run in sea water, fresh water, or any user-defined density. With two simple inputs, the orientation of the model in the Rhino coordinate system is defined. The output carries your company name and logo, and a project description.
Two forms of output are available; an Excel spreadsheet that includes both tabular and plotted data, and an HTML report that opens in your browser, nicely formatted for printing.
Next, the speed range is defined. The Design Speed is used for the drag reduction analysis.
Basic vessel data is all that's required. All other measurements are automatically taken from the model. If you have run RhinoMarine hydrostatics, that data can automatically be imported.
The Savitsky method is used to predict the bare hull drag of the vessel. In order to determine the required installed horsepower, two additional values are required. The Percent Design Margin includes your estimate of wind and appendage drag, and the Overall Propulsive Coefficient accounts for propeller and mechanical inefficiencies.
