Hullspeed Training

1 Background
Hullspeed is a resistance prediction tool. It uses a number of standard regression
equations to estimate naked hull resistance. The hull measurements and parameters
required may be automatically calculated from an existing Maxsurf design, or may
be entered directly without the need for a Maxsurf design file.
By specifying an overall efficiency, the vessel's power requirements may be
calculated.
1.1. Methods
Hullspeed is able to compute the hull resistance using the following methods:
• Savitsky (planing and pre-planing)
• Lahtiharju
• Holtrop
• Van Oortmerssen
• Series 60
• Delft yacht series
See the Hullspeed manual for details of the applicability of the different methods.
