Mooring springs-How do you use and what benefits?

[Woodstock]

Hi- I've seen a few references to mooring springs on here recently- and I hadn't heard of them before.

How do you use them and are there different designs

What benefits do they give over the usual pins

 

Thanks

[Guest leeparkinson]

A spring is used to stop a boat running backwards and forwards it is simple to use you simply put the rope in the opposite direction from how you normaly tie up

[Pen n Ink]

Just to clarify: the spring IS the diagonal rope - it isn't a separate item of kit.

[blodger]

I think the OP may in part be refering to the 'tensioner' springs put into lines to absorb shock. If so, a waste of money as not necessary (Seagoing ships do not use them either).

Snubbers are really only of any use in exposed coastal marinas where you can get a lot of snatch on your ropes with the wind and wave action. We have never found a need for them inland and rarely use them on the coast either.

 

The springs the OP will be refering too are diagonal lines set to reduce the fore and aft movement of a moored boat or lines which are set to allow for the rise and fall of the tide when moored against a fixed wall/berth. Completely different.

When you moor a boat to pins in a normal way, any passing boat causing drag of water and can make your boat surge, which can pull out your mooring pins. By tying extra ropes from the back of the boat to the front mooring pin and from the front of the boat to the back mooring pin this stops the surge of the boat and helps keep the mooring pins in the ground. Also when you tie your rope to the mooring pin use a clove hitch so the pin stays on the rope if it is pulled out and into the canal. Springs can also be used on their own where there is changes in the water level.

Not a particularly good diagram but it gives the general idea...

 

 

Slightly better one.

However most narrow and widebeam canal boats wont use ropes from the back to the front because this would mean carrying very long ropes. Most tend to use "half" springs where the ropes are taken to a third point either on the boat or the bank depending on how they have set them, if they use them of course.

 

We always moor using spring lines as they only take a few extra seconds to set but they do make for a much more comfortable ride onboard, especially as NC is such a light boat. With this in mind we have never had the need to complain about people going past our moored boat too quickly despite mooring in an area where a lot of the boats struggle to do the speed limit, but that is a matter for another topic

I Have to use a stern spring on my boat because I have an old ships life boat and there is not a straight part of the boat so for safety of my freinds and family I use it to pull the stern closer to the bank

I find a lot of people moan at boats going to fast because they don't tie ther boat properly they put there ropes straight to the bank instead of at an angle from the bow or stern

[nicknorman]

I don't think it matters whether the spring rope goes back towards the boat, or away from it. The essence is a longish rope running primarily in the fore/aft direction. Its ability to control fore/aft movement is the primary benefit on inland waterways. It ability to cope with changing water levels is the primary benefit on rivers and tidal water.

The usual way, on a narrowboat, of arranging springs is like this;

 

 

using a pair of extra pins and a couple of ropes, sometimes the rope is run from one pin to the other and then back to the boat.

 

sometimes you will see just an extra rope at the front.

 

 

don't be tempted to use a centre rope fixing (as most of the round profile boat diagrams show) unless it's on the gunwale, which would be unusual on a 'standard' narrow boat.

 

As has been pointed out, on a boat with round sides, it's almost impossible to keep still at a mooring without them.

That's exactly how I moor, stops the boat moving as boats go past

Even if the lines work slightly loose they still minimise the chances of your boat breaking loose. As the surge of a passing craft pulls you forward the tension is on the bow spring and stern line, and as you slide back the other way the tension is on the bow line and stern spring. So your craft slides backwards and forward alongside the quay rather than one end or the other pulling right out across the canal, and without pulling over as it does with a tight line tied at right angles.

[Woodstock]

As always- very helpful and knowledgeable replies- I've learnt so much from this forum

I did get confused because I thought it was to do with extra lines, but when I googled- I found some boat spring tensioners advertised- so all is clear

 

thank you

[nicknorman]

That rather symmetrical arrangement may be effective on inland waterways, but it is not really a spring in the conventional sense. More like 1/2 spring and 1/2 mooring line!

Centre rope fixing is OK provided the lie of the rope is mostly along the boat (ie in the fore/aft direction) since the angle thus gives rise to very little if any rolling effect.

I am so sorry Mr Norman, I thought we were discussing the mooring of boats on canals.

 

"not really a spring in the conventional sense"? What pompous rubbish.

 

If you would care to look a little more closely at the diagrams so kindly posted by MJG you will perhaps notice that neither of those arrangements are suitable for a narrow boat "in the conventional sense", so I posted a diagram of what I have observed people do in the real world on narrow boats and that fulfils the function required, that of checking fore and aft movement when a boat passes.

I disagree. Centre rope fixing, if from the top of the boat, is always bad in this context and will only ever increase the movement of the boat.

The lie of the rope in the way you describe is, to my mind, ugly, ineffective, likely to cause an obstruction or trip hazard and likely to catch on items on the roof. It will also, without the provision of fairleads, remove paint and lead to the early failure of the rope.

One of the reasons we were keen to move our boat. A short pontoon means we can only secure our boat with the centre and bow or stern line.

 

The centre line and the paint on the hand rails are both looking a bit worse for wear.

[Ray T]

Martin, slightly but I have one of these each side of the boat to run the centre rope in.

 

 

Before anyone comes on and says how dangerous, what a disaster they are, I have not yet managed to: rip them out, capsize the boat, snap a rope or hang the boat up in a lock with them.

Hi,

 

Just returned form a trip on the Southern GU, I found tying up as you describe the best way, for absolute comfort I found the floating a couple of inflated wheelbarrow wheels at each end kept the boat in deeper water and away from underwater bankside ridges.

 

Leo.

[nicknorman]

What pompous rubbish.

Naughty Pinkie! You have been such a good boy recently that I had taken you off my ignore list, and now you have gone and had one of your "wrong time of the month" hissy fits just because someone has a different opinion from you. Its to the naughty step for you (aka ignore list).

 

I thought we were discussing the mooring of boats on canals.

 

The OP was asking what springs were, he did not specify canal springs. Although this forum is CW.. it usually includes rivers, tidal and non. It would therefore be an incomplete answer to the OP to give only the method that worked on a NB on a canal, rather than mention the true origins of the word.

Yes, and useful it was too, but not really a spring in the conventional (ie global nautical) sense of the word. Still a handy way of tying up on a canal though.

Beauty is in the eye of the beholder of course, but I would prefer to be securely moor with ropes that might be seen as ugly, than bouncing around with immaculately manicured ropes.

 

ineffective

 

No, quite effective actually but I would presume from the tone of your rant that you have never tried it.

 

likely to cause an obstruction or trip hazard

 

Possibly, but less so than taking a rope back towards the centre of the boat from the front or back, as shown in your diagram. Any fool can see that. Oh - sorry...

 

 

without the provision of fairleads, remove paint and lead to the early failure of the rope.

 

mmmh, maybe you should try having some fairleads then?

 

Was there anything else? Oh, sorry I forgot, ignore list and all that.

Which actually has no place 'in the real world' where we boat because the bollards and or rings are invariably not in the correct place to be able to moor as you showed.

[bizzard]

Depending on the rise and fall of tide and wind strength and direction large ships can run out very long springs sometime four or more of them from aft going forward and from forward to aft, some short and some long, sometimes running out another half a ships length along the quay. A passenger ship tied up to a quay and using a hovering type of boarding gangway can have a positively cats cradle of spring and lateral cables run out to keep the ship still whilst passengers come and go.

Spring ? its nearly autumn.

Just a not on fairleads. If you are going to fit them make sure they are man enough for the job. Some of the ones for sale are pathetically undersized and will distort at the first pull of the rope through them.

It is worth noting Martin that the diagrams above are both salty water vessels and will have additional spring cleats at a suitable height for the job. Most narrowboats wont have the benefit of additional spring cleats to aid the lines.
