I'm sure you'll be OK with that.

No reason why not, but remember that if you have the rear roller too far aft then if you brake hard and your RIb isn't absiolutely rigidly held from moving forward, it could potentially fall forward. I almost had that on my first outing with mine, got to the water to find the centreline of the rear roller about 1/4" behind the transom! thankfully it was a 4 roller per side and so didn't drop. Yours being a twin roller if that happens you may need to go buy some fibreglass as you won't have another roller to support it should it walk foorward, and the beam will tip forward as the forward roller takes al lthe weight, it swings forward and your hull meets the metalwork below.......

Personally, I'd move the axle - It's easier if you are unbraked!

........ or buy a bigger engine

Moving the swing beam will have little or no affect on the nose weight unless you move the winching post too.
Moving the axle is easy. Just mark before you do anything and carefully measure the movements.

Exactly my thoughts, however JSP wants to get some support further back under the engine as well.
Moving the winch post forward would do this, but then the axle would need to be moved further forward than ever to lighten off the nose weight.

I think you're in for some fiddling mate, but that axle has to move.

This will have you head butting the keyboard. I've already got the nose weight spot on.

I have my reasons for moving things about though. Just no time to type it.

Before I do, does anyone know a reason why I shouldn't?

Last post: This will have you head butting the keyboard. I've already got the nose weight spot on.
Yup; That will do it.

I have my reasons for jiggling things about (such as launching), plus I have the use of a deserted slipway and road to keep trying it out until I'm happy I have it how I want it.
Plus, I've got no more nuts and bolts to mess around with on the RIB and I'm getting withdrawal symptoms

You could move the swing beam further back towards the ends of the trailer, however you will have to move the boat further back too by moving the winch post. It's at the winch post stage you can fine tune the roller positions relitive to the Transom.

BUT.....Why move things back if the nose weight is right? You realize that you could make the trailer unstable on the road by having a nose weight that is too light.

Oh yeah, not to worry mate. I've messed about with normal trailers for years. I've already moved the post and boat back on the trailer to get the nose weight right.
The bow is far to close to the hitch, when I'm putting the boat into the garden I have to jackknife it abit and the bow ends up touching the back of the van. Also want to set the trailer up so the transom is sitting lower on the trailer.
Believe me I could go on and on ...

And like I say, I have a deserted road and slipway to test things out.
