Twenty-five years ago HydroComp was formed with a mission to provide naval architects and ship builders with resistance and propulsion analysis solutions. HydroComp was formed as a corporation in 1984 by Jill Aaron, Managing Director, and Donald MacPherson, Technical Director. This partnership continues to direct HydroComp's evolution and growth. HydroComp now serves software customers and consulting clients in over 50 countries. NavCad is still HydroComp's flagship product, with users in all corners of the world from design to construction to academia. In addition to NavCad, HydroComp's software products grew to include PropExpert, PropCad, and SwiftCraft programs for propeller sizing & analysis, propeller CAD, and resistance and powering.
