Towing w/ 2015 D4

Hello and sorry for the dumb question. I think the following is correct for a Disco 2015 TD6

Kerb weight: 2570
GVM: 3240
Payload: 670
GCM: 6740

I’m about to buy a boat (Whittley CR2600 OB) with a trailering weight of 3350 (fully loaded). It seems on my calc thats legal and I’d have a very solid payload for the vehicle on top of 800kg or so which I’d never really use.

Is that right?

Thank you!
Tim

Are you in the UK?

The Disco has a 3.5t (3500kg) tow rating. So as long as the trailer and whatever is on the trailer (aka the boat) weigh less than 3.5t, it should be fine. There will be a nose weight that is applied to the toe ball, which then counts as payload on the towing vehicle. I don't know what the Disco is rated at nose weight wise, I'd guess 150kg.

Not sure what GCM relates too, normally you'd have gross train weight or Maximum Allowed Mass.
