With a 600 L tank Mr H. Tower is able to smuggle cheap fuel across the ditch?

I'd debate that point - if you are Front Wheel drive, then you have the weight of the engine above the axle = more grip . Most hitches (definetley the Focus) are max 50KG, so traction is better up front. Then there's the small matter that I can reverse my rear wheels onto relatively slippy stuff and as long as the front is still on the clean tarmac, I know I'll get back out.

Dare I ask what model of Focus you have? The max limits (in the back of book) will vary widely from the 1.6 petrol to the 2.0L diesel (and also the old & new bodies). I have one of the heavier Focus variants, and could legally have bought an unbraked trailer for my Humber. I only went braked to "future proof" it against any lighter cars I might buy in the future.



As for the max width, it's something like 2.3M max. That;s why if you see a Pac on the back of a lorry, the toobs are always deflated - the solid hull is not far off 2.3m wide - with the toobs inflated, they'd need a widre load escort to move it.

It's an original 1.8 petrol but thinking of upgrading to something with a meaty turbo diesel. Thanks for all the replies.

Downhilldai, would be interested to know how the weight of your 5.8 compares to the 6.2...

i was in same position as you when i bought my RIB a couple of weeks back. i passed my test in 99 so i also have the same restrictions on towing.

there is a LOT of conflicting info out there and the DVLA website does nothing to help that IMHO so i called the road police for an answer-

unladen is car with no spare wheel/driver and 3 ltrs of fuel

kerb wight is car with spare wheel, 90% full fuel tank and a driver of 75kg

MAM is the car, spare wheel, full tank of fuel and 4 adult passangers.

(all the above details ican be found stamped on your door pillar)

as an example-

my car is a vectra CDTI 150 SRI-

unladen weight 1428
kerb weight 1595
MAM 2005kg

my RIB is an avon 5.6 on a braked trailer with a MAM/GVW of 1100kg (that includes the trailer weight itself remember!)

the max i can tow on my licence is less than 3.5 tons which includes the car MAM and the boat/trailer MAM so my combined is under the legal limit. i'm also under the limit of the MAM of the trailer versus the unladen weight of the car so happy days.

the british caravan club advise not to tow more than 85% of the kerb weight of the towing car. remember though this was made with wind resistance of a huge caravan in mind so you could go a little more if you really had to "comfortably".

little word of warning-i got conflicting info on what the police look for or will charge you against.

i was told the 3.5 ton limit is the PLATED MAM of the car and trailer. i.e the theretical load it will take and not the actual-another police officer said it is the actual weight.......i'm under both so not a concern but worth a watch and clarification.

cheers

Around 1450 kg with 100 litres of fuel and a fair bit of kit onboard.
I haven't weighed it totally empty.

That's the gross weight including the trailer or just the boat?

Come down to my local slip and we can have a debate after I've recovered you

Weight transfer to the downhill wheels when on a slope seems to be significant - try reversing an empty pickup uphill in 2WD...... even with no trailer on the back my Ranger squeals the tyres if you don't take off very gently.

The whole lot, on a local weighbridge. Even had air in the toobs.
