HydroComp, Inc. began as a business venture in 1984 to meet the specific needs of naval architects and shipbuilders in the area of resistance and power predictions. Thirty years later, HydroComp has grown into a multifaceted corporation with clients from design to construction to academia in more than 60 countries. Founded in 1984 in New Hampshire, U.S. by Jill Aaron (Managing Director) and Donald MacPherson (Technical Director), HydroComp was a pioneer in the very specific area of applied hydrodynamics. This focus shaped a line of unique naval architectural software packages beginning with our flagship product NavCad, and which now include SwiftCraft, PropExpert, PropCad, SwiftTrial and most recently, PropElements.
