Mac:

Beam is 4'2"; design and precut ply parts from PT Watercraft, to a design by Russel Brown and friends in Port Townsend, WA, particularly Paul Bieker and Eric Jolley, as I understand it. http://www.ptwatercraft.com/ptwatercraft/PT11Home.html

James,
Thanks for the dimensions, information and link.
