Very much so, moving a rib on a four wheel trailer is hard work.

If you loose one wheel on a four wheel trailer will the remaining wheel and axle take the full weight? I don't know but looking at the tyre ratings I doubt it, and on my 4 wheel trailer it would mean the remaining axle taking nearly 100% overload, so either way your not going far if you loose a wheel on a four wheel trailer with a boat on it.

Finally the cost. A 1500 kg axle from De Graff is 350, or 700 for a pair.

Alko Bearings........

I wouldn't touch 'em with a Barge Pole . Unless you are happy to have the hubs & bearings fully serviced at ridiculously short intervals. As I understand it "sealed" means sealed against dust NOT water , especially the salty kind .

Pete - when I said 'manoeuvre to safety' I meant get the rig to the hard shoulder/verge safely! Surely that's got to be better than having the rig stuck in the middle of the road? Or would that never happen anyway?

We've got a twin axle caravan which is a b***h to move by hand. If we push it on the back of the car we get major wheel scrub, to the point where we removed a huge divit if grass on a campsite and had a very annoyed campsite warden!!

I have always known when a wheel was going to fall off, simply by the vibration and noise in the car, so it never came as a suprise giving me chance to find a nice spot to stop ( you will want a nice spot because its going to take the AA a while to get to you). the last time I had 20 miles of warning, just a shame I lived 22 miles away, nearly made it guess whose trailer it was

I have towed a 4 wheel horse box a lot years ago & it was hard work to move around! It is made essayer if you wind up the jockey wheel so lifting the first wheels of the ground!
I would stick with 2 wheels & check your bearings regularly & try not to submerge them when launching! I always keep mine dry

This I want to see.

Where do you launch from ? A skateboard ramp ?

When we launch at Crosshouse, the exhaust on our old Pajero is burbling under water and the sea is lapping at the running boards!

Took the Pajero back for a service a year later to the place that I had bought it from and they were truly shocked at the punishment I'd inflicted on it. 4 years later and it's still running (touch wood)

Normally at the Hamble public hard!
Ideally would use something with a bit More gradient but it is doable with my coaster 3 trailer & rib!

go for the Degraff trailer - but for more stability when towing go for twin axles-. Despite what previous posts say it is easier to reverse a twin axle trailer than a single one - as the single one turns very quickly and you end up at right angles to your hitch quicker than you can say " jack robinson".
But anyway - when backing down a slip- way - you are going to take it pretty cool. I have a 1994 degraff twin 30' trailer and only this year replaced
one out of the 4 wheel hub bearings. There are (were) rubber hub seals at the inner bearing. All bearings are TIMKIN ( USA) and require minimum maintenance.Wheel bearing replacement is DIY and you need a small sledge hammer,chaser and hub puller.
hope this helps

Jonathan

Pete, dont want to correct you- but the other day due to my inborn stupidity lost a back wheel as i had put the conical bearings in the wrong way.

The wheel went sailing pass me ---- but the trailer ( had the boat on as well) - was just as stable.
