Jeff and Marty, yes the New Horizon was built in Toledo, Ohio at Ray Greene and Co. and is a Sparkman and Stephens design. At the time it was the smallest boat they had designed.
I beg to differ, the manufacturer understood the materials, Ray Greene is the father of fiberglas boats! The boat was popular for having 6' headroom as well as roominess down below in the cabin.
If this boat had been poorly built as Jeff suggests there wouldn't be any sailing today, 50/40 years after being made.
Smooth sailing always,
