Interesting capsize and flotation study using Orca3D
Scott Graham of Graham Marine, Inc. is restoring a wooden Lightning class sailboat, and wanted to look at various options for adding flotation to make it easier to recover from a capsize. After building a detailed model in Rhino that accounts for the thickness of all of the parts, he looked at adding watertight bulkheads, airbags in various locations, and foam under the gunwales. Using Orca3D, he computed righting arm curves that include the effect of the crew and the buoyant mast for each configuration.
