Mooring pins

[WotEver]

I've just come across these:

The idea is that with the pull being where it is they suffer less from loosening through leverage.

 

I think they look good, what do the team think? Would they be less-come-loosable than traditional pins?

tent pegs, doubt they would hold my boat, and where to hit em with hammer?

I think that if the boat moves forwards and backwards it'll twist that loose in the ground. I suppose it will be fine if you get the mooring line and the top bar exactly aligned and it stays that way

 

I also think they won't take a lot of hammering

I have a pair made of bar steel some 40 rears ago. You hammer them in at the top of the angle. Best suited if mooring on springs. ( No not that sort)

Looks like a rond anchor to me

Well I had to go and google that but yes it does... so are rond anchors any good on soft ground? Better than pegs?

I imagine these are at that angle so that the pull is at 45^o to embedded portion. Of course, this would only apply if you were able to hammer the entire length of the spiky bit in. Otherwise it would be pulling on a turning moment just like an ordinary pin. And there's going to be precious few places where there's that depth of unobstructed ground. In my experience, any road.

[RLWP]

Thinking about it, it would be better if the two functions were separated. Have a strong straight part you could hammer into the ground without being restricted by getting the horizontal part aligned with the surface, then having a pivotted portion pointing out towards the boat pushed right down to the pin/ground interface. I suggest a longish, round pin with maybe a formed head, then perhaps a flexible textile based element to attach to the boat.

I don't like those things, can you tell?

Yeah, I was getting that impression

I wonder why somebody hasn't thought of that idea before

They do look very similar to Rond anchors to me also. We used them a lot on the Broads on soft ground and they wre quite effective. However it must be remembered that our boat at the time was a 40ft X 12ft GRP cruiser which was considerably less tonnage than our present boat and we have'nt tried using them yet so cannot say how effective they are on a N.B.

Regularly used to moor our very first 19 foot plywood canal boat with rond anchors, and it was generally fine.

 

I wouldn't want to try it with a narrow boat of any size though.

 

That poor little downward facing hook on these looks ill thought out. If you had already hammered them close to the ground, trying to pass a reasonable line with a back-splice on the end through them would be nigh on impossible.

 

"And for that reason, I'm not investing, and declare myself out!"

[FadeToScarlet]

They don't look particularly secure for the rope, either- without a full ring to pass the rope through, it looks like it could be easily unhooked, or even unhook itself if the mooring line goes slack.

[Tiny]

On the fens they all had them but no-one had a hammer so they could only push them a little bit into the ground and first boat past pulled them out. We were in a metal boat on pins which stayed in OK. I had to get the hammer out to help this lot who seemed to have little idea and bashed their anchors in for them. Hitting at the right angle was a fine art I found. Later I found a lot of these blokes pay anyone (a kid at one place earning hundreds each weekend) to work them through locks so maybe I should have charged a fiver an anchor to knock them in.

If they're supposed to work the way in which they look like they do then I can't see any advantage over ordinary mooring pins. Think of horizontal rope instead of the horizontal bar.

Normally inadequate stakes are pulled out by the top being dragged towards the boat to the point where they are no longer angled away from the boat, but towards it, at which point they can come out far more easily.

 

The horizontal part of the rond anchor will be against the ground when fully in inserted the bank, and this means that the angled part inserted in the ground can not be pulled over in the same way, and the inserted part should stay angled in a way that is against the pull.

 

I still would not try this design with a narrowboat though. At only 150mm long, they are going to grip very little bank, and I think it many surfaces there is every chance of them still getting ripped out.

 

Better to spend money on long enough stakes and a big enough hammer, in my view.

 

I have never had stakes pulled out by passing boats - ever.

If the ground was that soft for pins to be pulled out then I can't see the horizontal part stopping it. Besides, depending on the height of the bank, if you hammer one of these anchors down fully, the rope would most likely rise upwards at an angle from the ground to the boat so the horizontal bar isn't pulled horizontally and won't actually add much advantage because it's being pulled up.

 

I once had a mooring stake pulled out, but that was because I hadn't used a long enough stake. Now my shortest stake is 2' long and I've got a few that are 3' long.

If you go back to my humorous posting about round pins and flexible textile elements, you'll find I suggest that the rope is firmly down at ground level. Is that what you do, Alan?

Far better than any mooring pin (Which just pulls out), A rond anchor digs in and holds. When the 'Swamp duck' races passed the anchors hold, pins just pull out. For a narrow boat use the largest (3/4 inch).

I think I'll get a pair and see how I get on, thanks

Well it's chucking it down here, so you're in the right place.

I would really like to use these as they are clearly far superior to mooring pins. The biggest I can find are 3/4 inch from.

 

http://www.norfolkmarine.co.uk/shop-online/product_info.php?products_id=5659{2}16946

 

In fact the only place I can find on line that sell them.

 

The size looks big enough to me, but clearly digging up this old thread most comments are on a smaller version.

 

Has anyone used these on a wide beam??????????????? we're only 10/6 so not as wide as most.

 

3/4" (6170047) - Length overall 38cm, Fluke length 21.5cm, Weight: 1.5kg approx

 

I wouldn't see it being a big problem for a welder or Blacksmith to make the same a bit bigger and meatier if need be. Used off the peg though they are galvanised and ready to go.

I use those on my NB quite happily. Biggest risk is that they can pull up much easier than a pin, by accident or mischief.

Cheers oarfish, I've just also realised that I get more google response using Rhond rather than rond, so clearly there's another spelling.

I knew you'd find that (in a rhondabout way)
