The Display menu contains commands for setting the analysis parameters and solving the analysis.

Selecting Methods will bring up a dialog box which allows the user to select which prediction methods will be used. The methods chosen will be saved together with its required input data.

Selecting Speeds will bring up a dialog box which allows you to select the speed range over which the analysis will be performed.

Selecting Efficiency will display a dialog box which allows the user to specify the efficiency, , used to calculate the ship’s power, P, from the resistance, R:

, where

V is the ship velocity

The efficiency is entered as a percentage.

Selecting Measure Hull will cause Hullspeed to calculate the data it requires from the Maxsurf file currently loaded. The user will be asked to select the surfaces to be included in the measurement process. For designs such as yacht hulls, it is advisable not to include the surfaces, which define the appendages, such as the rudder and keel.

If this option is chosen, any data already input by the user will be over written by the measured values.

Used to set up the surfaces and bounding box to be used to calculate the slender body mesh. You can also specify the number of sections to be used and the colour of the drawn mesh.

All analysis methods other than the slender body method are computed as soon as any of the analysis parameters are changed. However, the computation time for the analytical slender body method is considerably slower; for this method, you must tell Hullspeed to perform the analysis by selecting the Solve Resistance Analysis command.

Calculates the wave pattern generated by the vessel for the specified speed using the slender body method.
