Marine Hull Resistance: displacement_monohull|Cb0.60|Rn10e8.0
Ship hull resistance coefficients for resistance prediction: ITTC 1957 friction line, Schoenherr line, Holtrop-Mennen form factors, residuary and wave-making resistance coefficients, and total resistance coefficients. Covers displacement monohulls, planing hulls, catamarans, SWATH, sailing yachts, and barges across Froude numbers 0.10–2.00.
