I agree, I estimate the trailer, outboard, fuel and other kit in the rib when towing to total just under 500kg. That's why I asked if the car has to be rated to the actual gross weight (500kg) or the plated max gross weight on the trailer (710kg for my trailer).

From answers so far it seems to be the later, so only the 180hp diesel engined Octavias would be legal with an unbraked trailer. I suspect that the majority of ribs being towed on unbraked trailers behind family cars are actually breaking the law.

Not a problem for me at present as I tow my sr4 behind a very big 4x4, but it seems to be restricting my choice of replacement vehicle when I change the 4x4 for a smaller more fuel efficient hatchback or estate in the future.

Think you may be looking at an old 2litre?
The current 2 litre, 150BHP hatch is 1255kg (they were proud to drop something like 150kg on the last re-design!) So unbraked weight is quoted by Skoda as 660kg.

The 184BHP will tow 710kg just.

The only octavia I can see that goes to 750kg now is the estate. (184BHP, 2Litre)

A lot of the smaller unbraked trailers exactly like what you might find a SR4 on are played to 500 or 600 kg...

I know you've a new trailer so probably doesn't apply.

If the weight genuinely is only 500kg, then all you need to do is get the trailer down plated and then you have a much wider choice of tow car.

I had a Honda accord estate which had a tow weight of 500kg unbraked as stated in the manual. I don't know why it was so low it wasn't due to the weight of the vehicle. My rib plus engine etc that I weighed when new was around 600kg on a 700kg trailer. Are you breaking the law or just invalidating any warranty as I did?

Just changed it for the 2wd mazda cx5 with unbraked tow weight 740kg. The unbraked weight of the Honda crv is only 600kg in the manual. I rate the Honda build quality but this was one reason along with fuel economy that I went for the mazda.

My intention was to upgrade the trailer with a braked axle but never got around to it. I therefore have a new tow hitch and braked axle available if anyone is interested.

The simple answer is that you were breaking the law due to being overweight. Although knowing what most warranty companies are like then you probably invalidated it as well....

For all these reasons, and the subjective weight of gear, fuel etc, I have decided to go with a braked 1100kg trailer for my new rib, even though it might come in under the limit.

I can live with the extra maintenance, but I am not gambling with insurance and warranties if something went wrong.

My rough calcs so please feel free to shoot them down:
SR4 dry weight (600lbs) = 275Kg
Outboard - unsure what you have but say a 50hp = 120Kg
50 litres of fuel = 50x 0.74 = 37Kg
Onboard electrical (inc battery) = 12Kg
Onboard others (anchor, wrap etc) = 15Kg
Total = 460 Kg
Assuming the towcar can tow 750Kg, that leaves 750-460 = 290 Kg for the weight of the trailer plus error margin.
If the tow car can only tow 500Kg, you may only have 40Kg for the trailer and error...
Does this look correct?

EDIT: Legal max as Trailer Guy mentions is 750Kg unbraked https://www.gov.uk/towing-with-car
Cheers
