Chuck, What do you mean by "fixed windows?" Aren't all good ports (windows) fixed to the coachouse, glued on, bolted on or other? I think maybe the ports that were glued on with Plexus and found on the 80's C&C designs were done that way mostly for appearance and not necesarily to add strength...I am skeptical about whether or not they added anymore strength than the framed ports did on the older (70's) designed boats.
