Guide posts

I'm finally getting around to finishing off the guide posts I'm fitting to my trailer. Hopefully without the arse end of the boat swinging around it will be easier for me to recover the boat by myself when required.

So to those who use them, probably more Ribnetters from over the pond to be fair, how are they set up?

Are they tight against the boat?
Or does it work best with a small, say 1/2", gap either side and allow the boat to sit to one side or another?

They are to be covered with Poly waste pipe, so will be slippery.

Cheers

Nasher

They can afford to be fairly tight as the tubes will compress quite easily if you are not perfectly aligned.

I swear by guide poles, with my past boat if you got the bow between the poles you were on the trailer...unfortunately I do not have them on my current boat. Much of the gap is going to be determined by the bunk layout. More gap is better if the boat will center itself up as it moves forward on the trailer. If more of a flat bottom type boat and it can sit most anywhere on the bunks then the posts need to be closer in. I would say at least 30mm on each side should be good.

Got a picture of the stern of the boat on the trailer showing the bunk angles etc?

Thanks Guys.

It's a Roller trailer so no bunks.

I'll design in around an inch either side to start with as with my design it will be easier to bring them in a bit later than to spread them out.

The uprights are 35mm OD thick wall tube which I'm having galvanised when I've welded the box section on the bottom.

Will post some pictures once I've done it as like usual I've done it slightly differently.

Nasher.

Most competition ski/wakeboard boats here have a PVC or ABS pipe fitted over the steel upright that allows it to roll. Often then a foam tubing will be fitted over that to protect even further (Of course that also makes them float which doesn't work very well as they have been known to float away, although a piece of rope inside solves the problem). To me, having something "roll along" as the boat moves forward makes sense.

I've got commercial uprights: A formed piece of square steel tubing rolled to a 90 degree "L", about a foot and a half per leg. The post is a piece of 1.5" PVC pipe that slips over the steel. I don't think I've ever seen the post "roll" while recovering (or launching.)

I have a couple of pairs of posts with the attachments for the trailer if anyone needs some.

I thought you drove your RIB on to your trailer like me? You did when I came out with you a few years ago?

Hey HT, how's tricks?

I do sometimes drive on, sometimes not, but am assuming either way will be easier with the guides.

The trouble I've found with driving on when you're alone, especially at a steep slip like the camber, is the boat rolling back off the trailer whilst you get out and attach the strap.
I have been known to leave it in gear whilst I jump out and attach the strap but it's a really stupid thing to do.

I've also figured out a way to have the strap on a line to one of the guide posts so I don't have to get out the boat to attach the strap to the bow eye via a short secondary strap.

Nasher.
