River Trent Eagre
Neil Purling
the River Trent.
How many of you uk boaters out there have seen this phenomenon?
I would like to see this too but I need to arm myself with information. What
is the best spot to see it I can go anywhere where there is road access to
witness this phenomenon. I needinformation enabling me to predict around
when it could occur.
Hopefully there are a few Trent boaters who have seen the eagre for
themselves and can tell me what tide tables to work from.

I think it's called the eiger but I may be wrong! If you can hang on a couple of days I
do have information about this. It's just that it's on my boat at the moment. However, I
might be going there tomorrow so I can pick up the info for you. These tidal waves happen
during the Spring and Autumn tides. I'll let you know as much as I can as soon as I can.

with these

It gives you some info to be going on with. Hope this helps.

I haven't seen it since the mid eighties when I left the area, but I
have seen it a few times on the Keadby - Stockwith section (roads run on
the river bank most of the way), it can be quite impressive on a good
day (as it can on the Ouse up at Selby). Apparently it isn't as good as
it used to be (what is) due to the training walls and other river
defence works low down.
It occurs at low water on the big spring tides, so work out when low
water is on the Keadby/West Stockwith stretch is. Get there early
(remember the tide times are predictions), and if it is a nice
day/sensible time of day you should find a few spectators around. May
be worth asking the lock keepers for advice. Having seen the effect on
a loaded gravel barge, I would suggest watching from the bank.

Nearly, it is just spring tides - but these happen all year round :-)
A spring tide is one where the sun, moon and earth are more or less in
line (the order can also be sun, earth, moon). This therefore happens
every half lunar month - or two weeks. The more in line things are the
higher the high tide and lower the low tide. Of course if things are
perfectly in line we also get an eclipse somewhere!
In the 'in between' weeks, when things are at right angles, we get
neap tides and the high tides aren't very high and the low tides
aren't very low either.
It is all to do with the pull of gravity on the waters of the oceans.
These tend to be pulled towards either sun and/or moon and because of
the rotation of the earth the waters tend to form an ellipse around
the earths waist and not merely a heap on one side.

One's on the Tent and the other's on the Severn :-)}
Actually in my business the Severn bore was Peter Scott's nickname! Not
to his face of course! In the same way any shot of an animal's
backside was known as an Animal Magic shot :-0}

I always thought everyone, but me found him rivettingly interesting.
Tel us more about David Attenborough :-)

At a guess, the difference is whether you speak Anglian or Saxon.

And there is one lady activist in matters to do with the Thames to whom I
have been known to refer as "the mouth of the Thames".

Don't you just hate rhetorical questions?

You wouldn't catch me on a narrow boat on the tidal Trent so this is
an academic question, but presumably you could easily sink a narrow
boat this way? Has this happened in living memory?

Yes. In 1971? a ~40ft converted ex Thomas Clayton boat (OHIO?) saw the
aegir approaching and decided to turn and run (BIG mistake - you
could never be fast enough) and was caught broadside and swamped. The
boat was quickly raised and continued in use for many years.
The point is you should always face the aeigir head on. I have not
done this myself but I am told there is a moment of panic as the bows
plunge into the oncoming wave but a second later you are 4 ft higher
and all is calm around you as if nothing had happened.
There is nothing wrong with the tidal Trent provided you keep your
wits about you. For safety's sake wear life jackets, have a *working*
anchor and follow the advice from lock keepers. Only a few tides
actually cause an aeigir and these are easily avoided if you plan your
trip according to the phases of the moon as described yesterdays
message in this thread. (Ie aim for quarter days - not full or new
days)

Scarcely had I written the earlier post than I read the article in
this month's Canal and Riverboat on NB Progress's trip to Ostend.
Wouldn't have believed it possible.

the lockies office. Great shot of an aegre hitting a beached barge,
side-on. It survived because the crew had time to ensure that all
hatches were tight - it just bobbed up.

my dad used to talk about seeing one on the Welland at Fosdyke, near where
he worked as a tractor driver. I don't think it exists there any more.
Dredging spoils the effect.
