Mooring Kit

[riverliver]

Hi. Might be a dumb question but I am looking into installing "something" on the river mooring to allow for rise and fall of water levels which in a bad winter where I am can be considerable. Picture attached of what I would like (with a mooring ring to rise and fall ) but cant find anything on the internet or even a name for what it might be. The pic looks like this might have been purpose made but off the shelf would be preferred. Any ideas? (and if there is a search word for it that would be a start).

thanks in advance

You are right. They are not off the shelf items. Not difficult for a metal fabricator to make and have galvanised.

 

[Refueler]

As T says - not an Off the Shelf item ....

But easy to make .... two metal 90 deg brackets and a length of stud bar and nuts. Ring placed over stud bar before securing of course.

Yes trouble is I'm a bit of a click n collect buyer. With all the folk on tidal moorings I am a bit surprised that there is nothing on the market

How about a long grab rail? Must be a huge number of different styles available.

 

[Pump-Out]

even a name for what it might be

They are called flood piles.

Yes trouble is I'm a bit of a click n collect buyer

Trouble is each set are made for the depth of water into which the pile is to be driven, the anticipated rise, and the angle of the mooring line for the size of boat for which it is to be designed. There is no "off the shelf" solution.

When the piles are installed the contractor attaches the bars. They last a long time and would guess the mooring owner would have them replaced when required. The market from individuals is pretty close to zero. Suggest you contact the mooring provider or the contractor for advice.

Appreciate you might be on a river given your forum name but the same principle applies. If you have your own piles then you will have to make or have made rise bars to suit your situation.

grab rail! why couldn't I drag that name out of the depths. You won't believe the number of search words I inserted (apart from that one) Could be an answer.

Pump out not sure if we are thinking the same thing here. I am looking for the metal "grab rail" ( (C) PCUK) not what its attached to

If you get stuck give me a shout and I'll make you some

The item shown in your photo is NOT a grab rail - it is just as described in post#6. Custom made to suit your specific location, and really not difficult to have made using stock bar and angle, although you will have to source a ring.

A stair handrail would be suitable

A better solution would be a solid bar bent in a "Z" shape each end. Each end would be forged flat & drilled to take a coach bolt. A ring would run up & down this. This has the advantage that there are no sharp edges for any part of a craft to catch on the corners of the angle brackets.
Quite common on timber piles in Dutch harbours etc.

There was a similar set-up in the Netherlands at Lauersoog in the tidal harbour. I was moored there one night and noticed that the moving ‘shackle’ had caught underneath the riser rod and was not going to free itself. Later that day I was able to photograph a local boat dragged down into the water as the tide rose and at risk of being flooded. If you are going to go for something like this, it has to be carefully thought out.

My apologies.

In that case you just need a blacksmith, or fabricator.

mmm... I'm not sure I'd be trusting my pride and joy to a handrail intended to take the load or one human being, and probably getting rain water on it at best (so not corroding its thin metal from the inside).

Personally, I wonder what advantage the metal bar brings over a fairly chunky rope with an eye splice it with chaff protection on it? I have seen something similar to this used on a stone pier but there was no option just to tie round the whole "pile" then.

I've moored often to such ring + bar .... and its a good system. But as said - a handrail would not be strong enough ...... handrails are usually thin wall tube ...

Shouldn't be much work for you to do. You have a photo, You presumably know how long you want it - All you need now do is google a metal fabricator nearby - show them the picture, tell them you want two of those of X CM in length and with holes for large coachbolts drilled and then collect.

Most if not all pulpits and pushpits are made of thin wall tube.

If you or ylop can provide me with the possible load on the mooring bar I can do the stress analysis for the size of handrails in question

My hand rails are 38 mm O/D tube and my bowsprit is 1 1/4 schedule tube.

I you wish to over design use 1 " schedule 40 tube that would take at least 20 ton pressure bender to put a bend in the tube

I have twice had to have pulpits 'bent' back to shape after far less force than a boat could apply to such mooring bars !!

Don't forget rings on as well - if closed bar setup
