My first fiberglass boat was a 1967 Glasspar Avalon with a Mercury 65 HP O/B on the transom. It was #2 of 19 (so far).
I picked it up used in the mid 70's. I didn't have to refurb it since it was still like new (it was originally purchased new by an old fart that kept it in his garage) when I got it.
I did add a lot to it though. CB, FF, gauges, indoor/outdoor carpeting, cockpit lighting, etc...
If a TV show called "Pimp my Boat" existed back then, I could have starred in it!
