Ribcraft 6.4 towing

I am in my second season with a Ribcraft 5.3, chosen after detailed study of the advice here - for which many thanks to all concerned. It has been great, and the whole family has had a huge amount of fun, but now I want to go bigger and have a new boat built. It will be definitely be another Ribcraft and I am looking at a 6.4 with a Suzuki 175. But that's getting heavy and I really don't want to change cars as well. So I could use some advice from anyone who has been down this road before me.

I have a Volvo V70 diesel estate which will tow up to 1800 kgs. And that is pretty much what a 6.4 on a double axle trailer is said to weigh (boat 975, engine 220, trailer 550) and then there's going to be some fuel in the tank, plus odds and ends. So probably too close to the limit for comfort. But do I need a double axle? If I don't, that's 150 kg saved for a start.

Alternatively, Jason at Ribcraft says they could save some weight by using Nedapan composite for the deck and stringers and a structural foam transom, as used on their specialist commercial boats. In my dinghy racing days, light was always good, but these days solid sounds better and - although I have great faith in the Ribcraft guys - high tech could end up expensive.

Any thoughts?

Welcome to Ribnet Curlew. The material is Nidaplast - and it will certainly save weight. It's more difficult to bolt things onto though and this needs to be considered at the time of the design. AFAIK, 1900kg is the most heavy duty axle for this application?

Personally I'd build a standard Ribcraft, lose the V70 and buy a truck...

Bigger tow vehicle. You will have the boat long after you change cars. "Don't spoil the ship for a ha'p'orth of car"
That's a healthy sized engine for that boat, if the boat is too light, you'll never keep it in the water.


Sh1t happens

I'm not a lover of twin axle trailers so if a single will carry the weight I'd go that way rather than lighten the boat you can change trailers later if need be.
Twins are numb to move by hand and cost twice as much to maintain
A properly set up single axle well maintained will be better than a marginally maintained twin. The danger is you think "I've got backup/can't afford/don't have time to maintain a twin" so you just use it anyway when you would probably be more concerned about a single and will actually look after it.
Used trailers sell realy well so if in the future you upgrade the car it may not be an expensive upgrade to change the trailer

How often do you expect to tow the new boat?

If it's beginning and end of the season then your needs are less demanding than regular trips.

We have Volvo XC60 D5 AWD (2.2t towing capacity). Avon Adventure 620/115hp Outboard on twin axle trailer, lighter than your proposed set up.
You barely notice it behind car.
We have also towed it with Peugeot 508 sw 2.o diesel (1.8t towing capacity) and you notice it much more.
Regardless of 1 or 2 axles a heftier towing vehicle would be my choice.
Whether you buy a hard core 4wd or a "soft roader" like us depends on the balance of every day driving versus how often you will be towing.

Let us know how you get on.
I like your choice of new boat btw

i have a ribcraft 6.8 so this may not be much use for you but just incase.

i know fact mine with an sbs 1800kg single axle trailer and full of fuel was 1910kg as i took it to a weight bridge. it was obviously over the legal limit for the trailer thanks to a cock up with the company i bought it from. they put it right though and i now have an sbs 2600kg trailer under it downrated to 2200kg currently, i have not weighed it yet to know what this one is but it should be about 2000kg with 220lts of fuel.

i tow mine with a nissan xtrail rated to 2200kg but i am in the middle of getting a proper 4x4 to do the job as sooner or later the clutch will give up and that is a 1k fix and best put towards an auto me thinks and a second car as i do 70 miles a day to work.

some people on here forget a car is meant for more than just towing a boat and automatically say just get a 4x4 and live with it, that is all well and good if the situaton suits you.

i am EXTREMELY loathe to pay 500 quid for road tax to sit in my driveway 99% of its life but that is the reality of where i am at as i choose not to buy an older bus and don't want the outlay of a low tax band new one.

Buy a new tow vehicle just for the boat. Considering you'll be splashing out 30k+ for the new Ribcraft, what's 5k for Discovery TD3.
