FREE!ship Plus - Hull modeling with subdivision surfaces and hydrodynamics of ship calculation FREE!ship Plus is designed to offer an alternative to hullform definition programs based on NURB surface modeling.

Calculations in FREE!ship Plus are based on the systematic serial tests of models of the ships and boats, inclusive more then 25 published methods and series for calculation of resistance of a hull and 17 screw diagrams of 5 types of propellers.

Integration of programs for calculations of ship resistance on method Holtrop-Mennen, etc. methods in the program designing of a hull form enables to carry out optimization of contours of a body line on to towing resistance of a hull with usage affine transformation and also to take into account in calculations resistance 11 types of appendages of a vessel and/or to estimate effect on resistance of factors of an environment, whether it be a wind, waves or a shallow water.

FREE!ship Plus is an innovative instrument allowing you to develop a hull form, to work a maximum quantity of alternatives of a projected vessel for powers prediction and propulsive characteristics, to calculate hydrostatics and stability, to receive resu
