Back when I didn't know it mattered I bought a new 1974 Steury Bass Boat with a 40 Johnson. It was a 16 foot fiberglass boat, got no idea what it weighed.
My tow car? A 1969 Volkswagen Squareback. There is a real possibly the boat weighed more than the car, but I towed it all over the state. Couple of steep ramps I wasn't sure I was going to make it but it always did.
Young, foolish, and broke!
