Being in the boat business in SE Florida since 1979, the only boats I KNOW were "transporters" were a 36' Cigarette, a 36' Mirage, a 36' Scorpion, a 33' Carrera and the center console Midnight Express. A dead giveaway was a low x-dimension, high fuel capacity and a 36" square foredeck hatch.
The aforementioned boats either came up for auction or were for sale when I was selling brokerage boats back in the early 80s.
I remember the Cigarette was dark green and the Midnight had 800 gallons fuel capacity and 4 200 Mercs. The Carrera had such a low x-dimension, it wouldn't respond to outdrive trim. The 36' Scorpion had #3 SSM drives and 6 hours on the meters. If I remember anything else, I will post again.
