Ribcraft 4.8 Weight - Unbraked Trailer?

Hi - Does anyone have a Ribcraft 4.8 or something similar?

I am interested in the actual 'real world' weight of the boat once loaded up with gear including 50l fuel, anchor, battery etc to make sure it would be within the 535kg weight limit for an unbraked trailer. In theory it should be but wondered how much of a margin there is to play with?

Car is 1400kg which I think legally has to be twice the weight of boat and trailer.

Cheers.

why not take the whole lot to your nearest public weigh bridge ,that way for a couple of £quid you will know for definate and get a recipt /certificate to prove it ,the weight of the trailer should be half that of the car if no brakes fitted ,so about 700 kgs for your trailer boat and equipment if you say your car weighs 1400kgs .

I would do but unfortunately don't have the boat yet.

The issue is I am potentially buying an unbraked trailer on the assumption it will be less than 700kg in total so was wondering if anyone else had weighed their boat as these thing always seem to add up to more than expected...

Im sure it will be under 700kg's. I know of 3 of them that are on unbraked trailers. But I dont know the exact weight. More like 600 - 650 would be my estimate.

My 5.4m searider on its trailer, 90hp Mariner 2 stroke, 2 man console, battery and 100 litres of fuel was about 740kg when I weighed it.

Not a 4.8m Ribcraft but a guide.

750kg gross weight is the limit for unbraked trailer - subject to this being ok for your car.

I have a Tornado 5m with a 60hp 2S on an unbraked Snipe trailer, which is what it came with from Barnet marine when I bought it from new in 98.

I estimate it's around 600kgs loaded with fuel and bits and pieces although I have yet to take it on a weighbridge.

I would be happy to think a ribcraft 4,8 was well within the unbraked limit.

Thanks. It should hopefully be well under 700kg including trailer but has a ski frame and stainless tank so dont know what they weigh. Engine is 145kg.

The hull is 325 kilos alone (dry):

With the engine that takes you up to 470 kilos, so I'd say you'll be under 700.

I'd give the guys at Ribcraft a quick call - depends on any extras fitted. I was quite surprised on the additional weight of the A-Frame, jockeys etc. Ribcraft were able to give an estimated weight.

I've seen a few 4.8's on unbraked trailers but I also guess it depends how much fuel / gear you have in there.

Good boats!

Agreed and often overlooked The manufacturers limits are the key check your handbook my laguna estate has an unbraked towing limit of 650kg
