Naval Architecture: Hull Design

A completed hull design is the end result of design iteration through calculation for multiple load cases, powering options, hydrostatics, stability, and seakeeping. Our hull designs start their journey as the preliminary 2D plan and profile. They are then reduced to data format, in which deadrise distribution, center of waterplane area, projected chine length, longitudinal chine angle, bottom loading, etc. are all calculated for varying load cases and centers of gravity incorporated in the weight study. These criteria and particulars are non-dimensionalized so that they can be both quantitatively and qualitatively analyzed, graphed, and compared to design standards as well as other completed vessels. After the data is refined, hull offsets or hard lines are developed into NURBS surfaces. These 3D surfaces are then be imported and analyzed further for hydrostatics, stability, and sea keeping. In this stage the hull will often go back for another round of iteration to ensure that all requirements are met and if not, changes in the hull data will be made. After a hull has been accepted in base form, final fairing of the NURBS surfaces is completed. Detailing of the hull then includes transom details, adding appendages (keel, strakes, tunnels, fairings, etc.) and required tooling details for a complete 3D model.
