I've found a 17-foot molded plywood 1959 or 1960 SEA FLY 17 foot open fisherman on a shoreline trailer up near Ft Hood, TX that needs "some love" & a complete restoration.
It seems that SEA FLY built molded plywood RUNABOUTS & DECKED OPEN FISHERMEN from 16-20 feet from 1956 to (probably) 1962 in Houston, TX.
That is essentially ALL that I've found about the company or its boats.
IF anyone here knows anything more about the boats or the company that built them, please advise by email to: firstname.lastname@example.org
