Keel roller or multi roller

[Adam and Hayley]

Having taking a chunk of GRP out of the rib while recovering on Saturday it occurred to me that multi roller would be kinder than my keel rollers to the hull. Does anyone have any view on this? My trailer is a brenderup with "super rollers"

Part of me worried that all of weight of the boat is on 2 or 3 points on the keel. Others have said that this puts least strain on the boat.


Any thoughts?

well without jumping to the wrong conclusion ,and never having expierience of the brenderup system ,sort of guessing if your boat is sitting on the keel rollers this may be wrongly set up ??? ,i would think the first keel roller is to lift the hull up onto the swingers ,i think you may need to bring the side rollers in much closer at the vee of the hull to hold the boat above the keel rollers ,i think in some cases keel rollers are there just as bump stops ..........sorry if i am up the wrong tree here !!

you could well be right. The chunk of grp would imply so and if it's not loaded dead straight the I find we're off and on until its sitting correctly... much to the annoyance of others as I drive out and then reverse back in!

yes ,if you bring the back rollers much closer ,then you will drive at the centre roller and the swinging rollers will quickly pick upwards and centralising will automatically take place , another thing many people do wrong in my opinion is dunk the trailer so deep to float on ,personally i load my trailer virtually dry (dunked only to the top of the tyre wall ) this way a good winch is a must but
lining up is much easier and bearings and brakes need less or no maintainance ,i do winch manually the whole way though after leading the boat up on the painter

I'd say try it again but dont go in so deep with the trailer so you keep weight on the keel rollers all the time. Keeping weight on the keel roller and tension on the winch line helps everything stay in line. I prefer the load spread over as many rollers as possible. And would try to avoid setting up the boat so its clear of the keel rollers

Thanks for your help. This is much appreciated

I feel your pain. Trying to hit a 6" strip in a current + wind can be a bitch. Missus is worse obviously

[Adam and Hayley]

.. regrettably my missus is much better than me (... Don't tell her obviously!)

Mine isn't on here so can say what I like he

I always set my rollers so that the gap between them is too narrow for the keel to “ground” on the trailer chassis. I don’t have keel rollers at the rear of the trailer.

Me too. You only need the breeze to be blowing and the boat will list a little and be slightly sideways too, your chance of aligning with the keel rollers will be zilch.

Multi rollers seem to work much better shallow especially when recovering. I had that if I went too deep the boat would end up on the up end of a roller and damage it.

The rollers on swing arms should catch the weight and guide you in prior to a keel roller in my opinion. Two roller trailers I’ve owned did not have keel rollers. If you go to fast you can over power the rollers and go over the top. Check for protruding bits of metal like lighting boards and maybe move roller set backward. My step dad gives subtle hand movements and I try to do it In one hit as the boat will turn quickly in the tide at calshot. Taken a chunk out of first boat so feel your pain. Drive into wind and tide and keep it shallow.
