Naval Architect Toolbox Plug-in for Rhino

KJ Engineering Consulting has developed a plug-in for the popular Rhino 3d design software. The plug-in is currently being tested and provides tools for the naval architect to more efficiently design and analyse yacht hulls.

The analysis tool calculates a great range of hydrostatic properties of the hull. The results can be written to a csv file for archiving or analysis in Excel. Additionally a graph of the cross section areas can be plotted in the Rhino window.

A balance tool adjusts the sink distance and pitch angle of a hull so that the centre of buoyancy matches the centre of gravity and the specified displacement. This allows to visually check how the hull would float in the water depending on displacement and centre of gravity location.

The most complex tool creates and analyses balanced hull surfaces in a range of heel angles. Each of the hulls created has the longitudinal centre of buoyancy located at the x- position of the centre of gravity and the displaced volume matches the input value. All results are written to a csv file for later analysis in Excel. In Excel it is easy to plot graphs of the righting moment, wetted surface area and other hydrostatic parameters depending on the heel angle.

A free evaluation version can be downloaded at food4Rhino. A pro version is available in our shop.

Below is a demo video of the naval architect tool box plug-in for Rhino.
