Dietmar Weselin loves to figure out how things work, and he's spent lots of time doing just that. Professionally, he brought his training as a design engineer to bear as chief executive officer of Walter Grinders Inc., a Virginia-based company that makes tool and cutter grinding machines plus scissors, knives, saws, and other products. When Dietmar retired, he and his wife, Mary Lou, who owned and operated an interior-design firm, combined their skills to bring Romany Life, a 1998 Hylas 54, back to pristine condition. The boat had seen hard use before they purchased it in July 2004, and it needed sprucing up. The Weselins had to refit almost every aspect of the boat.
