SeaHorse Hydrostatics is a Rhino plugin providing extended hydrostatic analysis for boat hulls. The plugin exposes a single main comand - shHydrostatics. Version query is available via the shVersion command. SeaHorse Hydrostatics is free to use, however consider donating to support further development.

Typical input characterisitcs:

• closed surface or polysurface
• the World XY plane is considered to be the water plane, so input must not be placed below or above the World XY plane
• bow must point towards the Origin of the World XY plane in order to get a correct rocker entry and exit angle
• sail area input is optional (in sqm, independent on document units)
• meshes are not supported

Output:

• LOA
• BOA
• LWL
• BWL
• LWL/BWL
• Draft
• CoB/WL
• CoB location
• CoF/WL
• CoF location
• Hull entry angle (given the fact that most boat hulls have a rounded entry at the rocker tip, the entry angle is given by a tangent vector a little bit behind the bow lower tip, that actual distance is now fixed, but could be an open parameter if requested)
• Hull exit angle
• Displacement
• Per inch immersion
• Hull area
• Wetted area
• Max underwater cross section area
• Water plane area
• Prismatic coefficient
• Waterplane coefficient
• DLR
• SLR
• Displacement speed (classic theory and light displacement craft)
• Sail area/displacement ratio
• Sail area/wetted surface ratio
• Bruce number
• Displacement curve (if the displacement curve presents kinks and weird turns, try tightening the document tolerances)
• Center of buoyancy
• Center of flotation
• A .csv file containing the analysis results

Further coefficients can be implemented on request.

Installation:

• download the installation package to your preferred location
