I'm trying to understand some terminology here.
My old man has taken his boat and trailer up to the weigh station and been given a scrawl with 2 numbers.
"Boat on trailer tare: 860kg".
That's fine.
"Boat on car: 940kg".
This is the one I don't understand. I'm obviously missing something, but clearly the boat can't weigh more than itself when it's attached to the tow ball.
Can anyone shed some light?
