I've owned both 18' and 20' SeaCraft boats and have had fly rod racks on both.
I'm lazy these days and the OP would do best to contact me directly as hosting photos on Photobucket just to re-post what I've posted here a decade ago ain't gonna happen.
If the OP wants to go down this road, email is
mark@markpix.com and there is a verification email bounce they will have to contend with from my spam filter.
