The moored narks!

speeding boats. I don’t want to be out on a limb, which I suppose I am
from what the general opinion seems to be, but I do feel that a number
of moored boaters seem to get unreasonably paranoid even if their boat
only moves half an inch because of a passing boat. It's a boat and
boats move for gods sake! Otherwise get a caravan.
Yes, some boats with total disregard go flat out past moored boats,
But I am sure the majority throttle down and go as slow as reasonably
possible, but there is still the abuse from the odd moored boat. V
signs, swearing and even things thrown. Those people are a bloody
nuisance and should not be on a boat! They spoil it for everybody by
giving line moorers a bad name and make it a pain for those passing,
especially when the line of boats seems to go on forever like the one
at Golden Mile or whatever they call it on the Shroppie just before
Chester.
I think we just draw up a list of known bloody minded moorers, name
the boats and where, and publish it on this group.

lines at 90 degrees to the boat to use the centre handling line as a third
mooring line, also perpendicular to the boat.
This ensures that the smallest fore-and-aft movement (which is inevitable
with perpendiculat lines) is autonmatically converted into a rocking
movement.
Although this rocking movement will initially be small it should be
remembered that the boat going past will result in a
forward-backwards-forwards-backwards pull on the moored boat usually called
the "forcing frequency" in vibration theory. If the natural frequency of the
boat surging forwards and backwards on its moorings and it's natural rocking
frequency happen to resonate with this frequency then there will be a strong
tendency for the surges to increase rather than fade away, resulting in a
violent rocking on the boat.
Now comes the interesting (or possibly boring) bit.
The forcing frequency is dependent on many several factors, the length and
draft of the boat, the depth of water, the profile of the canal and the
speed of the boat being the most obvious. This means that in some
circumstances you will cause a greater upset to a boat moored in this way by
going past slowly than by passing quickly.
It could also mean that a succession of similarly sized boats, all going
very slowly, could set off this resonant rocking while a single boat going
much faster will leave the boat effectively undisturbed.
Moral of this story:
Don't moor using your handling rope and make sure you have a decent spring
angle on your fore and aft ropes. It also helps if your mooring ropes are
ropes are attached to the boat at the centre-line rather than at the
gunwales.

It is for a similar reason that planes cruising at over 350 knots have swept
back wings. With straight wings certain forms of turbulence would cause the
wings to resonate, resulting in them flapping themselves off.

I'm rather glad about that John, at least Draco won't lose her (actually, it
was probably a he!) wings as we rarely get to that speed. Can't have our

Call me picky, but you might well end up with a list containing the
names of perfectly innocent moorers, whose name has been added to a
gulty list by some holier-than-thou @rseh*le who will never be
convinced that they ever offend in the first place
Roger Murray
Have you ever been driving along a country road Zeke, and coming
across a crouching dog by a farm drive waiting for every approaching
car, so it can dart out and have a good old yap. Well some moorers are
just like that dog, they see every passing boat as a target for their
yapping.
Yes have been a line moorer and have got pissed off with bloody minded
boaters going past at full revs and understand where you are coming
from, but the majority of boats do slow down.
The little outburst came after painfully traveling on a very wet and
miserable day past what seemed to be miles of never ending moored
boats on the Shroppie just before Chester, this I promise was at the
slowest and most painfull speed possible, to be met by twitching
curtains and the raised fist of a guy, shouting and hollering. I am
told that he has a go at every passing boat. He shouldn't be on the
canal.
Forget about the list, just the heat of the moment.
Roger.

Ehem.... before Sir (Pedantic) Aide gets hold of this I must gently
point out that swept back wings are in fact designed to reduce
relative airflow, and thus drag and turbulence over the leading edges
at the sacrifice of the coefficient of lift. Wings flapping and
falling off of are simply about strength of structure. That would be
an example of using ropes that are too thin so that they break (blue
string in BWs case). Rather than use this example of how boats should
be tied up, it is a better illustration of why your boat has a pointy
bit at the front instead of a square slab.
With regard to rope springs, usually these are long ties that reach
aft from the bow and forward from the stern of a boat to prevent all
forward and aft motion. They do not prevent the boat from rocking, and
they are not particularly practical for narrowboats, narrow boats or
narrow-boats. At dodgy moorings I use a system of triangulation,
whereby I take two lines out from the nearside mooring post and stem
post, and affix them to the bank at 90 degrees to each other so that
each line is at 45 degrees to the boat, two reaching for'd and two aft
from each post. (It is a mistake to use one line around two mooring
pins and back to the post as the line can then slip.) I find this
method makes the boat secure even where the ground is soft. It still
doesn't stop the boat from rocking when someone goes past at 4mph
though, so please slow down a bit.
thank you

job that our canals aren't used commercially anymore. He talks about
boats on the Grand Union going so fast that they would do a lock in 2
1/2 minutes! He also talks about Packet Boats that carried passengers.
They were pulled by galloping horses that were changed every 4 hours
and maintained a speed of 10 miles per hour! They had a scickle-shaped
knife fixed at their bows intended to slice through the tow rope of
any boat that got in their way!
Imagine trying to have a boating holiday with that lot around!! Worse
still imagined being moored up when they went past!

Either Golden Nook or Egg bridge moorings, I think. I used to moor just
north of Chester and have to go past the damn things every time I went
anywhere. i think everyone starts slow and then gradually speeds up
when they realuise that there is no end in sight.
I think they used to be just one side of the bridge, and then they
spread to the other side, and then another field got added. I have
always moored on linear moorings, but short ones - I can't blame anyone
speeding past a line as long as that one.

The liniear moorings just on the off side between Stretton and Ansty
have recently got longer.

Yes I do understand the yappy dog syndrome. However, the idea of
naming and shaming those owners of moored boats who do protest at
boats passing at excessive speeds is fundamentally flawed. Yes, the
majority of boaters are considerate, and do slow down, even if
sometimes their reduction in speed is insufficient. Trouble is, the
'naming and shaming' idea would give the minority of truly
inconsidreate boaters - lets call them aresholes - the opportunity to
publicly pillory those who, with good reason, object to their anti-
social behaviour. Or should we all suffer in silence at any bad
behaviour? Let's not go there eh?

Not long after the opening of the Canal du Midi (over 300 years ago) there
was a service called "le barque de poste". It was a type of "flyboat"
service (not a postal service) that left Toulouse on the morning of Day 1,
lunched at Negra before arriving at Castelnaudary for the first night stop.
Departing on Day 2, lunch was taken at Ecluse de Beteille, and the second
overnight stop was taken at Trebes. Day 3 saw lunch at La Redorte with the
third night stop at Le Somail. For Day 4, lunch was at Fonserannes and Agde
was reached that night.
These remarkable times were achieved by using a pool of 40 boats circulating
the canal. At staircase locks the passengers disembarked and carried their
bags up or down the locks before boarding another boat to save time. Even
so, 4 days is a remarkable achievement to travel approximately 240 kms and
pass through nearly 80 lock chambers on the original route of the canal.

Fom what everyone has said about 'On Line Moorings' the main problem would
be the length of the on line mooring. Would it be possible and practical to
limit the length of any on line mooring and then have a minimum length
before the next on line mooring? This length between the on line mooring
would also give the travelling boat a chance to moor for the night.

opened to normal navigation. Setting off from Porte Minervois next to the
Cesse Aqueduct, we arrived in Toulouse in 5 days.
Allowing another 2 days if we had set off from Agde, that would still have
been 7 days. We were at the locks at 0900hrs each day and cruised to cease
play at 1800hrs. In most cases we had lunch at a lock ready to be off again
at 1330hrs.
Given that we were following the "modern" route and crossing rivers by
aqueduct etc, I still think it was a remarkable achievement. Obviously if
the locks were open longer, you could reduce the time further.
The method used by Brian, ie to use red wine to reduce the memory of the
journey, does not really count in real time!!!

But we were stuck for 24 hrs because the air traffic controllers were
on strike, which for some reason meant the lock keepers were as well.

We had a number of moored boaters on a nearby river who frequently
complained about the wash from 14 foot sailing dinghies
as we went by. On one occasion when the safety boat was used in anger to
rescue some drowning people one guy
had complete apoplexy, jumping up and down on our jetty threatening to thump
everyone in sight. The safety boat planing
at 15 knots makes no wash to speak of at all.

It doesn't just seem like miles, it really is about 1.5 miles, and when
the continuous moorings finish there is still a boat about every 100
yards, so you're constantly speeding up and slowing down again. I
usually try to keep to the far side of the cut past moored boats, but
along there you can't as it's so shallow. I too got shouted at by one
man in one direction there a couple of weeks ago, but I have to confess
I had speeded up a little when I realised how long the moorings were.
I'm not prepared to go past 2 miles of continuously moored boats at 1
mph. On the Llangollen if we tried to go past boats at tickover we
wouldn't make any headway at all against the current. There's a 3/4
empty new marina about half a mile away from the end of these moorings,
he should go in there if he wants it quiet. I can understand that people
who genuinely live on board wouldn't want to live in a marina, but the
majority of boats appear to be empty for the majority of the time and
they should be in marinas when they are unoccupied.

Having been a keen dinghy racer myself in years gone by, I know what a
dreadful wake they make. ;)

I loved that. I can just imagine the scene. How aweful; should have let the
poor devils drown rather than creating a wake that might disturb someone.
Would have been wonderful if the planking on the jetty gave way!

That was when they had decent gate paddles
When we first moved onto the Wey in 1978 many locks had four gate paddles,
and by using them all the locks filled very quickly.
At St. Catherines Lock, which is quite shallow, it was almost impossible
for me to get the fourth paddle up before the gates started to open!
This was OK for a small 19 foot cruiser like 'Linton', where we could
sit safely at the back of the lock. For hireboats there was
a strong risk of filling the boat with water, so the NT have
now limited the working paddles to two. They tried halving
the paddle hole area on Catteshall and Unstead bottom gates, which
dramatically increased the time required to empty the lock - especially
if one paddle was out of order. The experiment was not
repeated when the gates were replaced.
