Solid naval architectural calculations and diagrams are needed to give the neccessary underlaying basement for a succesful design and certification to CE- or other criteria.
Check and re-check of weight, weightcontribution, hydrostatics, hydrodynamics and aerodynamics are processed by using advanced and specialised software programs such
as for instance PIAS for the intact- and, if needed or wanted, damage stability information.
When needed we tow-tank a scale model or make complex CFD calculations.
