Dubois Naval Architects LtdFEA Solutions have done stress analyses work for us on several sailing yacht projects, including the full hull fabrication analysis of a very large sailing yacht. They were working off our 2D drawings, created 3D CAD models and 3D FEA models. Their FEA reports are very detailed, and the results well explained in the de-briefings they give. We are happy to recommend their services. P. B., Senior Designer
