About Jim Antrim

A graduate of Webb Institute of Naval Architecture, Jim Antrim founded Antrim Associates in 1979 after apprenticing with leading naval architects Dick Carter, Britton Chance and Gary Mull. His design portfolio is one of the most diverse in the industry, and includes record-breaking custom multihull and monohull sailboats, popular production boats, wing-sail assisted motor-catamarans, and recently, a solar-powered unmanned electric craft.

Always keeping an eye toward efficient innovation, Jim's expertise in composite engineering yields high-performing and weight-effective structures. Jim has developed several computer programs used in laminate engineering analysis, as well as performance analysis and prediction. His services are often sought after by other leading naval architecture firms.

His love for the sport of sailing ensures thoughtful, fun and leading edge designs
