Planing hull: Fridsma series, parametric Rhino

Parametric model of the Fridsma (1969) planing hull series, a classic reference for planing and CFD studies: 9 in chine beam, L/b 5, constant deadrise 10, 20 and 30 degrees. Geometry from the published series parameters; bow planform and keel profile assumed elliptical. Rhino hydrostatics checked against an independent calculation (volume within 0.002 %). Free-floating at load coefficient 0.608: draft 51 mm at mid-length, trim 1.5 deg by the stern (LCG assumed at 62 % L). Files: 3DM, STEP.
