Hmm. Ive hit things with my trailer over the years and its Never Failed like that.
Admitidly its a steel tailer. but even so I would expect a trailer to be able to take a fair ammout of knocks and bumps as they need to due to pot holes,speed bumps crap roads etc.

Looks like poor welds and poor ally. IMO.

Ali goes slightly brittle either side of any welding line. I would guess that if you look at the trailer it has failed next to a weld

If you look at the weld pics on page 2, it appears that the "weld" was actually just bead; no fusing of the base material, based on how cleanly the two pieces separated. Not the best weld job IMO.

i was down there on friday chatting to some lads in the yard, they said that the damage was as a result of the trailer having been jack-knifed and the boat shooting forwards and damaging the short wheelbase landrover that was towing it. Apparently there is an investigation going on to find out the cause of the accident !!

Well, trailer arrived in Stockholm on Friday, carrying a 2800kg boat, with no issues.
I have only had the trailer since last year, and have now sold it, I found it towed really well, and seemed more than capable, and a lot cheaper than the trailers sold by SW RIB Charter.

Accident damage then and not a 'catastrophic trailure failure?' I thought SW Rib centre were a little disingenuous with the reporting. I've seen several Gullwings at QAB which is right on Michaels (South West Rib Charter aka South Coast Boat Trailers) doorstep.

I always thought they were quality trailer

Isn't that what everybody will now be coming out and saying anyway ? Before knowing the full details we (me included) were all saying poor design, poorly built etc. Turns out it may well be driver error after all...or maybe not

My point is let's wait and see before jumping on any bandwagons

As a saddo trailer type I'd be interested to hear the facts and the manufacturer's side of things before coming to a conclusion.

...just a possibility?

OK, so the trailer was shock-loaded when the boat LEFT the trailer (or attempted to leave the trailer anyway ) and not while it was loaded onto it.......but i was close

As AMac already suggested, the dimensions of the profiles used dont seem to correspond with a trailer designed to carry nearly 3.5t...

If the trailer is genuinly designed to carry the coresponding load, is it possible it was shock loaded when the boat was loaded onto it?

I wouldnt expect to see weld failures on the swing beam clamp from any kind of cyclic stress as that area shouldn't be flexing as much as say, the main longitudinals....
