Swath hull split strut
Splet01. feb. 2024 · With the use of Chebychev functions, a given area, centroid, and even inertia can be imposed on a curve that is later modelled with a B-spline curve. In this way, the SWATH struts can be designed with a given Waterplane area, LCF and inertia, and then combined with a SWATH Lower Hull definition to obtain the ship's displacement and LCB.
