Trailer Set up

Picked up the Dixon Bate trailer for the new Osprey and unfortunately it had not been set up properly.

Even with then engine on the back of the boat there was so much weight on the nose that I could hardly lift it. When I looked at it I could see that the axle was set quite far back on the trailer so I moved it forward about 18" which has given a much more reasonable weight on the nose.

Now I am looking at the front set of rollers and thinking that they look too far back on the trailer as well. Does anyone have any pics of their set ups.

Any ideas?

Bear in mind when you look at the photo below that this was taken after I had moved the axle forward 18" so you can see what I mean about it being too far back initially!!

If you're setting up a DixonBate watch the rollers on the chines-mine cut into the rubber on the rollers on the front sets where the chines rubbed on them.It made the outer rubber covering on the rollers split.
Dixon-Bate were fantastic though-sent me a set of rollers without quibble under warranty.

I think you need more rollers than that. I don't know what their capacity is but its less than a bunk and you have very little support under there right now. Both the front and rear set should be 1.5 to 2x longer IMO. Only THEN the front set extend a bit more forward on the hull. But just moving the forward set up is going to leave a huge unsupported gap in between.

My old set up was very well balanced if it helps!

Main rollers look ok to me .. hard to tell from the pic, but you are missing one under the bow which you will need to stop draw bar bounce

I find this set-up just about spot-on with my 5.8

Its there Just needs adjusting.

This is the standard trailer that Osprey supply with the 6.5 and I dont think I need more rollers. Once the boat is on the water I can try a few changes to the set up.

Mine is as per the picture and no problems the distance from the transom to the rear pivot point is 600 mm and between pivots is 2700 mm I measured a trailer at Osprey with their demo 6.5 on to get my setup and I think it's about 75 kg on the hitch with everything on board and a full tank of petrol 220 L

Might help as a starting point

Not sure if these two pictures help at all. Even after engine went on it was still a little nose heavy, but acceptable. I haven't bothered to adjust anything yet, but you should be able to guage the position of the axle.

Erin, thanks for the pics, you can see when you compare that on yours the front set of rollers are further forward.

And I can also see that your axle is where mine was when I collected the trailer. I think you will find that you have to move it forwards 18" or so if you want to get the balance right.
