Graves Yacht Yard (USA)
Located in Marblehead MA, and one of the oldest concerns of it's type still in business in the US. (2010) Founded by James E. Graves, at the turn of the 20th century, initially for the building of racing (rowing)dories.
A wonderful article appeared in the 'Marblehead' magazine (2006?) by Mildred Graves Stetson, the founders daughter, that covers the history of this establishment. The current link (2010) is:
