Jim Antrim, often called the Wizard of El Sobrante, is a naval architect who apprenticed under Dick Carter, Britton Chance and Gary Mull. He’s designed record breaking multihull and monohull sailboats as well as popular production boats. He’s an expert in composite material engineering and has developed several computer programs used in performance analysis and prediction. I met him in his office to talk about many of his designs and how he got into naval architecture in the first place.
