Besides Hullspeed's regression methods like Holtrop, Savitsky, Delft et al, there is also an analytical method available for ships with a high L/B ratio to determine wave resistance. In v12, you have more control over the geometry that is used to calculate the wave resistance of slender vessels.
It is now possible to cross reference heeling arms into several criteria. This means that the heeling arm only needs to be defined and updated in one location, yet can be used in several criteria. It also reduces the clutter in the GZ-graph.
This video shows how the new Automation features in Maxsurf, Hydromax, Seakeeper and Hullspeed enable you to write Microsoft VBA macros in Excel (or Word, Access, etc.) A Maxsurf model is generated from a template design and parameters entered in an Excel spreadsheet
Seakeeper polar plots
It is now possible to view the vessel response for different speeds and different headings at the same time in a polar graph. play
