Its not! Not withstanding the fact that an average man is 83.6 kg (in the UK, 2010) having the weight in the boot (probably directly over the rear axle) is rather different from having it positioned on a lever perhaps a meter behind the axle. Perhaps even more importantly passengers or cement are sitting pretty still in the boot, whilst the tow ball load is dynamically changing as the trailer passes over bumps etc. Of course the manufacturers spec assumes you also have your car loaded - which in many cases with people going away for a long trip it will be! It is unusual to find "family cars" in the UK rated to take 100 kg nose weight, even though they may well be rated to pull 1600 kg.

Ultimately though, even if the car can take it without the handling being affected you can expect that if it falls under scrutiny (either by an insurer or the authorities as the result of an accident or a random* stop) then being massively over the manufacturer's stated nose weight limit isn't going to be good.

Finally from a purely practical point of view anything too heavy becomes impossible to lift on and off the ball which makes you reliant on the jockey wheel (which we all know are liable to jamming under excess load) and harder to manage when moving around without the aid of a vehicle.


* And having a car that appears to be sitting low at the back because of a heavy trailer is a good way to get selected 'at random'.

Generic recommended stuff is well dangerous.

Your vehicle will have a max hitch load. Over here in sunny Europe it's usually 75kg for your average "family saloon / hatchback / estate". The key point is "max".

Let's pur this in perspective. How am I supposed to get 75 kg nose weight on a laser dinghy which clocks in at 58 kg. ?

My rib hovers around the 45kg mark. The whole trailing load is approximately 75 kg......

I wonder why the Uk has much lower ratings than the US and Aus, my light 4x4 has a tow rating up to 2500kg and a towball rating of 250kg. As for getting heavy loads onto a tow ball simply back the vehicle to the hitch then lower the jockey wheel.



easy guide to help when backing up alone



easy guide flipped and locked to stop theft and chains crossed incase of boat coming off the hitch somehow, we also have to have d shackles with ratings on by law

Most manufacturers of cars put a recommended nose/tongue weight of a trailer in their handbook, so I doubt you'll have to calculate anything your self.

I would look at moving my trailer wheels back to get the desired nose weight. That way I keep my trailer longer and keep a more flexible arrangement for the future.

If you need to shorten the draw bar then using scales you can jack at various points along its length to measure nose weight and decide where the chop needs to be made.

Of course another option you have is to have an internal depth transducer. Obviously this doesn't work if you have a speed paddle wheel version.

Seems that every site I look at backs the aprox 10% and the RACQ claim the light weight limits on European cars can cause the trailer to become unstable RACQ - Trailer and tow vehicle specifications | Cars & Driving

Your own Racq link says often around 10% but can be much lower or higher. That is rather different from should be 10%.

It's remarkable that with all these unstable trailers across all of Europe that we manage to manoeuvre our cars around the inevitable carnage! I have certainly seen trailers crashed, but I've also seen that in the USA.

You cant compare with the likes of the US or even Australia both have a much higher trailer boat community.

Statistics found online state approximately 50000 power boat owners for the entire UK. New South Wales (one of 6 states an 2 territories) also my home state has 215000 registered power boats. Given most of us don't have boats on moorings most of these are trailered. Boats that dont travell over 10 knots and sailing vessels dont need to be registered so dont show in those figures.

Given we have more trailered boats Ive yet to hear of any tow ball issues, I also works as a marine rescue volunteer and have owned boats for 38 years, would of thought in that time I would of heard of the odd problem.

I do find that when anyone asks for any advice on this forum there seem to be people waiting just to dissagree and post the even when they are shown links etc backing the claims. Opinions are like assholes we all have them.
