Your alternative would be to heat up the bent bit whilst tightening the U bolts.
I agree with everything you said, I guess one never knows till it happens and this is going to be a venture into the dark in some aspects. I take a little comfort that my local slip is only 6 miles away and all slow roads

Bit of an update! Things didn't go to plan today, I hadn't factored on the drawbar not regaining it's original form and have ended up cutting off one end of my fabrication so that a modified angled plate can be welded into position

This is beggining to turn into a bit of a saga, story of my life where boating is concerned at the moment.

I'll fit the masts instead this weekend.

Do all of the bits attached to the box section bolt on(winch post, hitch etc) and what size and wall thickness is the existing box section, should it be a straight piece

I've just found out today that a Halmark trailer drawbar is the same design, the box is 10mm smaller at 70 square, but that should be a problem. However they can only supply with a 2m long one, mine is 2.5m's. I've got to run the rule over the trailer in a min.

Is that bracket just two bits of flat with an airgap between? I think you should have used square hollow section. the flat will have very little strength to compressive forces without a top and bottom to stop it twisting. I would guess the whole affair adds virtually no strength to the drawbar in the direction you need it as the flat plated will just bow. Get the 9" disc cutter out and start again! It will be better in the long run.

Couldn't use a box section as the brake rod goes down the middle, I had already though of what you're suggesting and had some spacers made to bolt the sides together after fitment.

Might cut my losses (not that it's cost me anything yet (except for loss of boating).

I'm considering buying another trailer if one can be found at the right money, getting the Admiral repaired with a drawbar purchased from indespension and selling it.

ahh that makes sense then! i suppose you could run the brake bar through a tube but that doesnt leave any room for error/futher bending!
You could sell the trailer bent! it would save the hassle of fixing it, i am sure there are people on ebay (myself included when i needed a trailer) who would happily buy a bent trailer if they have access to a disc cutter and a MIG. it would only take a half a day to fab a new drawbar and 80 to get it galvanised. (unless you know someone who has lots done) I bet you could sell it and buy a brand new one for the cost of a two or three tanks of petrol, or if you leave it a month or two one tank of petrol, next year a litre

Different Makes of Trailer

Being a little paranoid about long drawbars has made me want to go for a trailer long side beams and no or little drawbar, so what sort of options do I have for a 6.2m RIB weighing no more than 1200kg's and keeping with a single axle. I have found a Bramber but is rated at 1100kg's capacity which I think is a little low.

What do you guys think?
