Yes but was it a warm day?

Admittedly my whole rib+trailer only clocks in at around the 750Kg mark full of fuel most of which isn't there when I recover it. The car is about half a ton heavier than it's "piddly petrol sized" cousins, so it may not be as big an issue for me as some!

So how steep is your slip? - I've yet to find one where I couldn't get back up. (Famous last words moment - Cue disaster next outing on flat, clean...... ) Seriously tho' I'd be interested to see the maths for that, considering the percentage of the weight over the front to start with.......

Assuming you want to stick with the blue oval, current Focus (well ,the pre facelift current, assume new new will be similar) 2.0L estate clocks in at 1600- ish Kg. Rated for towing 750Kg unbraked!

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
It's all done on plated weight AFAIK.
i.e. for a cat B licence, the combined plated weights of the combo must be under 3500kg, irrespective of the actual weight.
If you exceed the plated weight limit of either vehicle (or even an individual axle) then they can prosecute you for overloading.

That can't be right. I checked when I was lugging mine around, and I didn't need to do anything to my tubes, and it's 2.7m wide. Think about how wide some caravans are - and I'd guess that they are up to the max width.

He's kind of right! http://www.dft.gov.uk/pgr/roads/vehi...frequently4577 although apparently the government's website is out of date: http://www.ntta.co.uk/news/news_details.aspx?NewsID=11

So the maximum width of a trailer (behind a car) is 2.55m. However you are allowed to have the load overhang the trailer by (I think 30 cm) on each side - so your boat can be bigger than this.

I would have to agree that front wheel drive is useless on a slip trying to recover any sort of weight.
The tow hitch weight and weight transfer because of the slope means most of the weight is over the rear wheels.
Even on a flat piece of ground rear wheel drive will put more power onto the tarmac because of weight transfer when accelerating, hence the limits on power on front wheel drive powerful cars.
I have watched, with lots of supressed giggles, the antics of some folk trying to recover any reasonably sized boat on our local steepish slip using front wheel drive cars. There are lots of rubber marks from these attempts.........

you should have seen my first attemp at recovering mine last weekend for a laugh!!! inexperience with a rib/roller trailer, rough sea and a FWD car is a recipe for a good laugh.

because i have a FWD car i went with the rope it up/down the slip method and it works fine albeit if it is a busy slip you better turn up before the crowd does or you will get dirty looks due to the time taken.

to try and speed things up and keep me/car safe i bought an electric towbar winch setup to do the job for me-will try it this weekend and report back.

cheers

This may be where I win- the whole lot fuelled only weighs in at about 730KG. (weighbridge weight) after a day's entertainment, there's about 60L of liquid missing......... Also my hitch nose weight is probably nearer 40Kg so all that "extra" weight isn't as bad as some...

True, the slope will transfer some weight, but taking the Focus as an example - Mine clocks in at 1600Kg. If I load the boot to max GVW, I can see the wheels dissapear into the arches. That doesn't happen when I hitch up. It also doesn't happen if I park on a slope, so once again, I'd like to see some maths, which I'll try to do if I can get over the weighbridge in the next few days to get the axle weights.

If weight transfer was such a huge problem, how come all front wheel drives don't come to a slipping halt when towing trailers or with a full boot when driving over the Gross Glockner or that nice hill on the York - Scarbrough road?

Agreed, but if the rear wheels are on slippy stuff when the front are on the solid stuff, that extra traction is about as much use as a chocolate fireguard. I know which one I'd rather try to get out!

Yep, and I've also smiled at the smell of many burning clutches...... There are three important words here: "clutch", "throttle" and "control" - With a big turbo diesel, it's possible to get sufficient torque to the wheels without winding the turbo up so the torque really kicks in & the tyres let go. I've successfully recovered on the public slip at Blairvadach (it's a cobbled slip onto this http://www.geograph.org.uk/photo/87921) numerous times with a Focus.

Yes, If I was dragging a ton & a half of 7M boat with a huge engine and full fuel tanks to match around then yes, I'd be looking at something bigger & 4WD, but with careful choice of boat & car, use of a saloon or estate should not be an issue.


All I'm saying is that as per usual with ribs, the absolutes of a given item are not as important as the whole set-up!
