Trailer setup shallow slip

[Tom P]

Hi All
After a bit of advice on launching my ribtec455 on shallow slips. When I come to a shallow slipway its a right old bugger to push off, managed it a few times on my own but take a lots of puffing/swearing and shoving the boat up and down!! Here are some pics of the trailer setup, I think its a fairly large trailer for the boat (used to be a braked trailer apparently). So any suggestions/ideas about moving rollers or setup of swing bunks? Would towbar extension be the way to go?
Thanks in advance
Tom

How about an electric winch up front with a snatch block secured at the rear for the cable to loop and a v-roller at the front to position the cable and let the winch pull it off.

Can you not lower the rear swing beam and move those rollers to an outer chine? Possibly also lifting the front rollers?

The idea of a roller trailer is that it needs little assistance to roll off and on the trailer. Id suggest that maybe there is something not quite right with one or more of your rollers.

Also, make sure the bow is slightly higher than the stern as this will aid with rolling. With mine, if I release the winch cable, it’s already unloading it’s self 🤣

Yep a couple of tweaks to the trailer should get the boat wanting to move back, looks to me like the front swing beam is too far back & maybe putting too much weight on those few rollers instead of being evenly distributed. I'd look at moving the front swing beam forward slightly and move the rollers closer together & the rear rollers possibly further apart and down if thats possible.

Yep possibly a few rollers stuck or partially siezed often boats start to roll as soon as you unclip the winch I have to take a bight with the painter on a 5.4m I have or the boat moves before you can unclip the winch strap

Swap the rollers for the hard blue ones, game changer

Looks to me like someone has modified the mini swing arm brackets so you have no height adjustment from from front to back
call extreme trailers they will sell you the bits you need


Heres one i prepared earlier ,hard rollers will also help as ian sugests but i am partial to the orange !

Good shout. I'd missed that the front rollers are set too far back. Also on mine I've got a bow roller attached to the drawbar. And look how far forward the front carriages are.

As an aside, I set my snubber higher than Tom's, should help in the event of a car crash. I also fasten the bow down with a strap, not good to rely on just the bow ring, winch or winch post U-bolts.

To me it looks like those swing brackets are both set the same: ie high. Rear beam can be dropped. The brackets don't have to be vertical on the chassis rail, can be set on an angle and the swing beam will adjust.

Moving the rollers to an outer chine helped a lot. Also with towing stability. Every single U-bolt sheared, I couldn't be bothered cutting the nuts off and they were rusty anyway. Got quite expensive!

Rollers are the way to go. One very inexpensive roller design is a bunk roller. I have used it on several SIBS and RIBS. Slides right off and easy to crank back up with your wench when you don't want to bury the back of your vehicle in the water. They come in 4'-8' lengths. Take a look at some examples here:

Thanks for all the replies and photos, very useful. Will try the front swing foward a bit and rear rollers out some, think I will be the same Limecc and shearing quite a few of them!!
Will price up some of the harder blue rollers Ian

Thanks again everyone

Hi Tom

Your boat appears far too high on the trailer. So was mine until I was advised to move the axle from under the frame to the top. It looks as if you have enough clearance above your mud guards, but of course measure it first to be sure.

Do you want the full monty or maybe a hat over the tackle?

I have been trying to work out how to do this myself without pulling the winch strap against the bottom of the boat. Got any pictures or ideas? It seems impossible to me but I also need the ability to help my boat off roller trailer.

As already stated, the forward roller cradle is far too far back. Hence all the weight of the front of the boat is sitting on the bow snubber - that'll be why its so hard to shove off. Move the forward cradle further forward which will take the weight off the snubber and you'll have no issues.

Smaller I know but same principle: with the setup below on the slipway the whole boat will roll back without any input from me as soon as I start to unwind the winch strip. Also means I can drive the RIB on and off single handed if thats easier for the situation.

I’ve got a box of hard blue rollers for sale if your interested?

[Salty Pete]

I suggested before that changing the axle to above instead of below the frame would lower it. It would but maybe the bottom of the trailer would be too close to the ground.

The trailer looks like it was made for a boat with a deep skeg that is why there is so much clearance between the keel and the trailer frame.

As has already been mentioned the boat is riding too high on the trailer.

The drawbar is long enough and the boat looks like it would float off if it was lower on the trailer.

I feel that the OP needs to get rid of the construction under the rollers but without having the facilities to do it would be difficult. The restricting element is the clearance above the mudguards.

P.S. Does this trailer have springs? I can't see any.
