Next time I get to the yard, I'm going to check the whole trailer set up.

Will order some new rollers as well. A web search suggests polyurethane rollers best for grp hulls, these seem widely available outside the uk, not so apparent to buy in the uk. Any recommendations or does everyone just go for the blue non marking rollers that seem to be widely available?
look on e-bay blue rollers you can buy sets to suit

cheers

It all depends on your slip. Our local is very steep so if i reverse until the trailer hubs are wet, the stern would be floating off. Instead I tend to launch with a helm (usually me) on board until the trailer tires are just wet then wrap the painter around the winch post, let slack off of the winch strap and unclip, then let the painter out gently using the friction from the winch post to keep the speed in check. Helm then drives off and docks in the marina. If on my own, I let the boat out on the painter as above then drag alongside the slip where it can be tied up whilst I sort the trailer.

Recovery involves parking the trailer with the hubs just clear of the water and driving up the trailer to the missus can clip on the winch line and wind it in. If on my own, I use the painter to position the boat then winch all the way onto the trailer. I tend to climb down the trailer beyond the waterline so I can clip the winch line without getting wet feet.

At a shallower slip I'd stick the trailer much further in but where I am I can avoid dunking the hubs.

Trailer setup

Had the boat out today and had a chance to have another look at the trailer setup.

Firstly, the boat did come off the trailer a little easier, but I had squirted all the rollers with some WD40 first! A new set of rollers will be ordered in the next week or two, I think the rubber ones are a bit past their best.

Boat looks fairly level on the trailer, I was expecting it to be higher at the front than the back to aid with launching. I checked all the roller mountings and they are all mounted at the same height all round using the same mounting holes. I did also check a number of other trailers in the yard and they all seem to be the same, so it looks as though mine is ok.

Next was the moving mounting brackets. One bracket (with 2 rollers mounted) is really loose, all the others are really tight with little or no movements available.

The nearest trailer to mine in the yard had all the rollers fixed with no movement so I'm unclear what the correct setup needs to be.

I can tighten or loosen the nut/bolt holding each mounting bracket to make more or less movement.

So, a couple of questions
1. Should the 'mountings' onto which the rollers are mounted, be free to move either a little (tight) or a lot (loose)?
2. While the boat is on the trailer, should I slacken the mounting bolts to make sure that all the rollers are sitting in the right places, might help given I know many of mine are really stiff and no movement available.

I found aan old post from 'trailer guy' with some useful info; making sure rollers aren't on the chines but straddle either side plus making sure rear rollers are as close to rear/transom as possible and preferably spaced a little wider which would in turn lower the stern slightly on the trailer and help with launch and recovery.

I'll have to take my tape measure and spinners next visit to make some adjustments, I thing front rollers are ok, rears could probably be made slightly wider.

dont forget the slipway will give you the angle to roll off your rollers [not seen your trailer]but keel will be static and roll easy, carrier rollers mine had two sets stern & two thirds to the bow approx they should move to accommodate the hull passing meaning the hull isn't the same shape all the way mine had a floating carrier at the stern to aid recovery meaning it floats forward and back also the rollers tip the same and side to side if that makes sense that means if the boat come at an angle the rollers and carrier line it up, all rollers should touch the hull when transporting. the keel and the stern carrier taking the brunt of the weight.i did find might only been me but i set the last keel roller with another behind it in piggy back[hitch side ] higher so when the bow hit the two i then set my winch post snubber to hit at the same time that stopped the bow climbing off the front set of rollers and the hull banging during towing

I thought a couple pics may assist!

trailer has 16 rollers, all a bit old. the rear 8 are on a swinging cradle.

I'm not sure if i should have more rollers!

Boat is a 5.85 Ribcraft with 150 Mercury so theres a lot of weight on the back.






does anyone think i need more rollers, particularly at the rear??

That looks Bob on to me and a good design I think you just need a bit of maintenance to make her roll that might be changing rollers for new or just a grease up have a play before spending money

Cheers

I'm not saying that you do , but when you consider that weight bouncing about at the rear end during any reasonable tow , it could only help ?

Here's a poor pic of my Ribcraft 5.85 with Yammy F100 and Susy 5 auxilliary. The reserve container for the auxilliary is also set quite well back , so it's nice to know it is well supported ( 8 rubber rollers on each side at the stern ).

Making Rib Cover...

Go easy on yourself ! There's no substitute for experience with many of your present " niggles " !

Mine has 4 sets of 8 on swing beams and a few keel rollers. It only makes contact with about half of those on each set as the hull is quite curved so I really wouldn't worry about yours. It looks fine.

Just make sure the carriers move in the direction they should if they don't tilt easy they will slow the hull down when pushing off.
