Keel roller bracket for trailer

[simonfraser]

I have trouble centering the bow on the small roller on the aft part of my trailer, if I miss the roller the bow hits the metal trailer bar to the side of the bow roller
By accident one of the newer park and ride guys drove the trailer in 'too deep' and the side rollers centred the RIB perfectly, but according to the yard boss the tractor should not be immersed so far

Have been looking at posts to centre the bow of the 4.5m RIB, but the trailer is not launched deep enough for this to work

So was thinking of something like this

But it would need to have a guide on bot sides, and preferably a proper centering roller too

Is this made ? Or can I buy side rollers ?

I have seen easy glide systems, but am concerned I would ride the bow up in between the wheels

You can buy side rollers to create quite a comprehensive roller set

Ours extend beyond the keel roller and tilt to accept the incoming hull. You can just see the keel roller in the picture below.

However I would suggest if the trailer is not deep enough for your rollers to work then the yard boss needs to "grow a pair" as if the trailer is not deep enough then his tractor is only paddling and could go deeper. I guess he is trying to preserve it from salt corrosion.

We have a drawbar extension which really helps the trailer go deeper, or you could use a rope/strop to let the trailer go deeper.

Fitting side rollers to the first roller will make a big difference. See attached photo. I also found that because I climb the boat onto the trailer rather than floating it on (to keep my wheels and brakes dry), the first roller is under a lot of pressure and was reluctant to turn properly and caused the keel to slide on the roller and create a groove. Layering the roller with rubber bands cut from an inner tube made the keel grip the roller and thus turn properly.
