Art Anderson Associates has completed a number of naval architecture projects that have involved hydrodynamic analysis of hull resistance and power requirements. Often, these calculations are performed as a part of a repowering or renovation project, but they've also been components of some of our advanced research projects with the United States Navy. Our naval architects use software tools such as NavCAD to analyze the resistance of both displacement and planing vessels and use our professional knowledge and judgement to select appropriate engines and drivetrains. We also have experience in more rigorous forms of resistance calculations that include model development and tank testing.
