Hullspeed - Resistance and power prediction

• Interactive interface
• Automated hull measuring
• Multiple analysis methods
  • Planing vessels
  • Workboats
  • Ships
  • Sailing Yachts
  • Multihulls (via Slender Body method)

Hullspeed lets you estimate the resistance and power requirements for any Maxsurf design using industry standard prediction techniques.

When designing a powered vessel using Maxsurf, Hullspeed provides a wide range of calculation methods to help you estimate the resistance and powering requirements of the hull. A range of industry standard algorithms are provided, allowing you to select the methods most appropriate for the hull shape you are designing.

Calculation methods provided in Hullspeed include: Savitsky pre and post planing; Lahtiharju for planing vessels; Holtrop for fast displacement hulls; Series 60 for large ships; van Oortmerssen for full form hulls such as tugs and trawlers; and Delft systematic yacht series for sailing yachts.

As well as traditional regression based methods, Hullspeed now includes the Slender Body method to perform first principles analysis for relatively slender monohulls and multihulls.  An automated tool for form factor estimation is included within this analysis method.

Hullspeed can automatically read in any Maxsurf design file and measure the required input parameters from it. You also have the option to override these automatically calculated values to fine tune the calculations to match your requirements.

Like all modules in the Maxsurf range, Hullspeed allows you to copy and paste data to and from other Windows programs allowing you to carry out your own data preparation or post-processing.

Output from Hullspeed is provided in both tabular and graphical format and is automatically recalculated as changes are made to input parameters.
