Re-creating and analyzing a 17th-century sailing ship with Rhino, Grasshopper, and Orca3D

In her senior project at St. Mary's College in Historic St. Mary's City, Maryland, Rebecca Prasher studied ship hull form design methods from the 17th century, and reproduced the rules and methods in a detailed Grasshopper script. Using the script, she re-created the hull shape of the Maryland Dove (a replica of the Maryland Dove is homeported in St. Mary's City), and then she studied the effects of varying vertical center of gravity and beam on the stability of a sailing ship. Her report makes for very interesting reading, with significant background on the historical naval architecture texts that she used, detailed explanations of the rules and methods that she found and the Grasshopper script that she wrote to apply them, and finally an analysis of the stability. It's an impressive look at what can be accomplished using Rhino and the broad range of available plug-ins such as Grasshopper and Orca3D, together with some good research and creativity.
