When I was actively practicing naval architecture and yacht design, I established a number of working relationships with boat builders, mast builders, custom fabricators, naval architects, boat designers, yachting and boating magazines, and other professional organizations around the country and around the world such as are listed below. Of equal importance, and for that which I am most proud, are the websites of my family listed at the end.
