Later I will add a dissertation on tilting trailers and sinking trailers. For the moment I will just add a pic of my original wobble rollers for the benefit of one of our friends on the Careel site.

I fitted the side rollers on my Investigator trailer. Two sets, one as seen here and one about a metre further along the trailer. It worked a charm. However you do need to feed the bow into them at the start, and that means you cannot "power load" like the stink boaters do.

Hi Ian,

Just reading through old posts and my next trailer job happens to be keel side rollers. ! My first attempt at attaching the originals has failed, they are too far apart by about 1" each side .so may just weld the axle posts straight onto the aft beam , which was the method my trailer had before. Have considered going wobble rollers but this should be cheaper.

How are your support posts attached ? cant quite see it in the photo. Cheers

The rollers are bolted on by U shaped brackets. These were standard some time ago. You can see the vertical clamping bolts across the end of the U in the photo.

I made up a couple of rails for my trailer from 50mm square RHS and bolted the brackets to them. The advantage is that the rollers are adjustable and can be positioned further aft to make retrieving the boat a little easier. I had to modify the RHS to sit vertically on the rear cross beam, but apart from that, this arrangement is simple. I would recommend putting in another couple of verticle rollers to keep the keel centred as you winch up. I installed the rails several years ago and have had no issues with this setup.

Only problem I can see Ray, is some nasty sharp edges that you can hit with the boat, (or shins, Ouch!) if things go wrong. Usually this bit is underwater if you tilt the trailer, so not that easy to see.

Thanks for the extra info, sorry i didn't see it until today and already went ahead with a custom system for the guide rollers. Used the existing frame clamps and had to weldup doglegged guide roller holders to get around the aft double rollers but still allow movement of these.

Your systems look good, having the adjustment in two directions. My one only adjusts vertically, not horizontally so hope they're the right location widthways. So far the keel seems to sit fairly well centered in the dry land test... :)
