I had the same hull, only 16'9".
Brunswick bought the original Fisher line and name, and slapped it on a boat they were already making, Spectrum. They started making them in the early 90's, I had a 1995 model. I believe it was Brunswicks first venture into a welded hull.
Hated it. Very thin hull skin.
Hull was all dented up around the supports just from running in moderate 1' waves.
Very stern heavy.
Tried lots of tricks, props, trim, engine height, nothing helped the constant porpoising.
And due to having no external strakes or ribs, the hull would slide in turns, and track poorly.
Glad its gone.
To bad they didn't leave the original Fisher line alone. It was a premium boat that was all aluminum, wood free, back in the 80's.
