I like that system but part of the issue with the trailer last weekend was that the relatively small keel rollers don't really hold the bow in place and as it comes up it rolls off to one side which was how I damaged the hull. What I need is for somebody to invent a bloody great big keel roller about 2ft across and about 6 inches from the top to bottom of the V, that would do the trick nicely

I really like the snap-on boat securing system too - might have to filch some of those ideas, much better than buggering around with ratchet straps and rope

Would something like this help? These are called Eziguides - and the idea is that they are spring loaded so help align the boat over the rollers. I've never actually seen anyone use them - but they are not too expensive, and might avoid some major work.

In the example wear baldy bangs his head on youtube, did he use the winch to pull the boat off or was that just the winch spooling out under gravity?

Didn't get the idea of that second off last line he clipped on, if had broke loose it would have slid off at least a metre probably two. I have seen a bottle screw used for his last connection. We take a few turns around the winch post with the painter as a supplemental line.

You can get anal though - second winch post (incase first gives way)
Multiple D rings on keel - I ve seen it probably weakened it more than strengthened.

the back swinging one has 40 rollers on it, not really an H more of a T.
all the rest are like a T with lugs welded on the top and the rollers are on solid 3/4inch bar again with a lug on them.
the back lot swing backwards and forward as well as side to side and the whole arm swings as well, all the rest only swing side to side.

I find that most people having trouble getting square on the trailer have problems because the trailer is too far into the water. With a RIB having a deep V, you might find you can back most of the way in, but then power your way up onto the trailer (being careful of your lower unit...)

In my case, I only have about 2/3 of the bunks in the water. As I power up the boat self-centres on the bunks (I have 2 on each side).

On Sunday, we recovered the boat on a ramp that was in a river with a strong side current. I came onto the trailer at a good clip to maintain steerage, with the engine tipped up... and drove her right up into the nose chock. And this was with three sets of twin tanks and three stage bottles...

Try it and you might be surprised how well it works...

Stoo the problem is with this trailer and other similar layouts, if you F it up and miss the rollers, you run the hull up on the metal part of the trailer.

On my old trailer I used to do much as you describe, the worse the conditions the further out of the water the trailer would be but usually about 1/2 out of the water, whack the boat on with a bit of momentum and it would self centre and sit there securely whatever happened, whereas with this one you'd only need to go off a bit sideways and you'd need a lot of new gelcoat...

When I power load (which isn't all that often), I do pretty much what Stoo does, except I usually put the bunks in about halfway, rather than 2/3 (kind of trailer dependent, I'd guess. Swell and such also affects how deep you need to be.)

Having the motor trimmed way out should give your prop additional clearance, and it also tends to lift the nose of the boat, allowing it to slide up the bunks a little easier.

Normally, once I get the bow up to the stop, the boat will sit nicely on the bunks while the truck is eased up far enough to secure the winch strap and safety chain without having to get wet or balance on the tongue while you hook things up.

I don't know how this would work using a roller trailer, though, as I have zero experience with them.
