Securing rib to trailer

Good evening,

Just collected our rib this afternoon. The rib was strapped to the trailer via the winch strap, plus a rope tied into the frame then the d ring under the bow. The back end was secured with two ratchet straps to d rings on transom then to trailer frame.

My questions are.....

Is this the best way to keep the rib secure on the trailer?

Should I use a strap across the top of the tubes?

How tight should the underneath straps be....should the be very tight to not allow any movement or should the be any play ?

It towed fine but was a little concerned when not on the motorway and minor roads were uneven...

Don't strap over the tubes, you risk bursting them and will add wear and tear to the fabric.

IMHO you want the ratchet at the bow and stern tight enough that the boat isn't bouncing around on the trailer.

i ratchet mine with 2 straps at back through the D rings you mention with HD ratchets to the swing beam.

I also ratchet my outboard to the trailer to minimise it bouncing.

At the front i use the winch and a ratchet strap.

You will want them tight and ideally check them every 5-10 miles then tighten again, you will get a feel for how far you can go before checking again, i'm normally 20-30 miles depending on the roads. motorway is obviously more but not often it is on motorway for me.

HTH

cheers

In addition to the winch, I have a nice wide ratchet strap going from the trailer to the bow eye at an angle of about 30 - not so much to keep it on the trailer but to stop (or at least slow) the boat in the event of an accident that brings things to a sudden stop. The boat might be blunt and full of air but I don't want to see in my rear-view mirror the boat coming through the rear window, or watching it slide down the road into oncoming traffic or pedestrians.

I strategically replaced some of the nuts on my trailer with galvanised eye-nuts (or what ever they are called) and lots of threadlock. The tie-down straps at the stern are point-to-point to the boat with no scope for movement. I still check and, if necessary, tighten the ratchets a couple of clicks after a couple of miles though.

The boat is securely fixed to the trailer but other than driving very slowly and avoiding potholes where possible there's not much than can be done about the trailer bouncing around on the rubbish roads round here.

All good advice above, a support from the outboard leg to the trailer and a ratchet strap to snug it down are worth considering too.

Thankyou all for your advice.

I will replace all straps for new ratchets and an additional for the outboard.

It was a little unnerving to se it bouncing around on the minor roads....even at low speeds.

Towed my Avon Adventure back from Kingsbridge yesterday on B roads and by the time i got home it had bounced around a bit and was sat a little sideways on the trailer. A bit unnerving to see how much it had moved when i got home (only 20mins). Looks like a visit to screwfix for some more ratchet straps for me too!

On a related note, and as I'm about to get a roller trailer which will be a bit more critical in terms of strappage, what's the accumulated wisdom on the strength of a bow eye in terms of what it bolts into inside the GRP? I presume they usually have some sort of metal backing plate inside the GRP but I have often wondered about the loads imposed by winding up straps and ropes etc all on to one little eye....

good question!

i always assumed (dangerous) that they were designed to pull the boat onto the trailer from the ground. i.e they should be able to take the weight to move the boat up and over the first swing beam (in my case). there is way to work out the load but it is probably in the region 1/6th the boat weight. i.e you couldn't ratchet it down hard enough to do anymore damage than winching it on in the first place.

i'm happy to be proved wrong by others as the above was just what i figured.

should also factor in the boat your doing it with i guess and consider build quality perhaps?

cheers

Can I suggest stainless steel ratchet straps. Your day can then start with out rusty hands!

I have a customer who supplies them - he's also got his own RIB although I don't think he posts on here.

Buy Stainless Lifting Slings and Ratchets at www.rapidmarine.co.uk
