Wow, some of those YMBARN if lines about boats really brought back some memories.....
I've had rod holders on my former P18-2, they were detachable though. Landed my biggest King Mackeral ever on that boat, 53"! I didn't use the hulls for bait wells however.
I used a piece of an old windsurfer boom to permanently fix a broken tiller crossbar on that same boat.
