About HydroComp

HydroComp, Inc. was founded in the 1980s by Jill Aaron (Managing Director) and Donald MacPherson (Technical Director). The two partners continue to direct HydroComp’s evolution and growth, resulting in a dynamic consultancy known worldwide for its software and services.

NavCad remains 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 include PropElements, PropCad, and PropExpert – programs for wake-adapted propeller “design for performance”, geometric propeller “design for manufacture”, and application propeller sizing for smaller vessels.

HydroComp provides a broad range of technical services to companies large and small through engineering services using the same commercial software sold to the maritime industry. We utilize a progressive internal research and design program to keep ongoing technical services at the cutting edge of contemporary knowledge and expertise. 

HydroComp propeller designs are in most sectors of the marine community, including submersibles, the AUV/UUV communities, foil boards, and other recreational equipment. Even industries outside of the marine community come to HydroComp for propulsor designs, such as for commercial industrial mixers.

HydroComp continues to develop software tools for the future with core values rooted in pragmatic design. From ship operation and duty-profile analysis, including fuel consumption and carbon footprint to underwater radiated-noise models, we develop tools for the next generation of smart, sustainable design. 

Demand for such tools takes HydroComp around the globe. A significant international presence results in a family of customers and consulting clients in more than 65 countries. Most of the world’s major propulsion equipment manufacturers and research institutions count themselves among HydroComp’s clients. Carefully-selected global representatives support this worldwide effort with localized attention and support.

HydroComp’s team is justifiably proud of 35-plus years of enthusiasm by its staff, its dedication to the original mission, and the loyalty of more than 1200 companies directly influenced by HydroComp software and services.
