Default What way to edge.

Now I'm confused. Doing my two star training we did a lot of edging, both on
calm water and for getting in and out of different flow rates, you lean left
you turn left - no problem.
I just watched a Kayaking DVD "Performance Sea Kayaking" in which they
covered edging to turn the boat. They all turned the OPPOSITE way to whci
they edged the boat!
Have I missed something?


Yes,
but the question is, do you want to have all the information there is
about leaning and edging/heeling when doing a two star training? Most
instructors don't want to make it more complicated than necessary,
I guess?

With canoeing one normally speaks about 'leaning',
and with kayaking one normally says 'edging' when you 'heel' a boat.
When I say 'leaning' I mean the action one has to do to make the boat
'heel', because you can also heel a canoe without leaning, for instance by
kneeling with two knees in the bilge. Furthermore you can make a difference
between a boat lean (a.k.a. J-lean) and a body lean (a.k.a. bell buoy
lean).

Which effect you get when you heel your boat, depends on the design of that
boat, which way/side you heel the boat and how much you lean the boat
and the way the boat is moving through the water.

Also you can heel the boat for different purposes.

* To give the boat a tendency to turn in a certain direction.
With forward speed most designs 'want' to go to the right with a heel to
the left and vice versa.
Some designs will do this the opposite way though! Can also be different on
the amount of heel.
Experimenting with your own boat is the only sure way to find that out.

* To make the boat more maneuverable.
The more you heel the boat, the more shape in the water of the boat changes
to a more maneuverable shape. Especially for straighter keeled boats this is
recommended by many people, but personally, I consider this only useful as a
fla****er technique. In waves and current I prefer a design that doesn't need
to be heeled to make a turn. I care more about stability then...

* For stability purposes.
For instance when encountering great differences in current,
one has to heel the boat downstream.
(Preferably not more than is really necessary.)
But also with hard side winds I heel a bit into the wind.

* To keep an open canoe 'possibly' dryer by heeling _temporarily_ away
from a wave. (Only recommended if you know when and how to do it!)

Although the text is in the dutch language, the pictures on:

may make some things I wrote here more clear?

If I might offer a little gloss on the above. I think it's useful to
use the words "lean" and "edge/heel" (kayaks edge, open boats heel)
separately. Edging refers to the boat being other than flat on the
water. It does not refer to the position of the body and head, which
remain vertical and balanced. Leaning indicates that the head and body
are not vertical and not above the boat. Obviously, the boat will be
edged when you do this, unless you're in a very stable boat. You can
sustain an edge indefinitely, a lean results in a flip unless something
else--brace, bow, dock, whale--intervenes.

Another way to think about it: you edge your boat by diferentially
pulling/pushing with your knees; you lean by moving your torso
sideways.

Most of the time, edging is preferable. Low and high brace kayak turns
are the main places I would see a lean being used. So edge in to the
eddy, edge as a beam wave passes under you.

To the OP: in WW boats you generally edge into the turn, bicycle-wise,
although modern boats turn so easily it really doesn't matter, you can
stay flat except when crossing current differentials. In a sea kayak,
you edge to the outside of a sweep turn, so that (1) you turn quicker,
with less resistance and (2) you are supported by your sweeping paddle
blade.

Heeling is used for all kind of boats,
edging is mostly used for kayaks and closed canoes,
and leaning is mostly for open canoes, also because
the action of leaning is more a kneeling thing, I suppose,
but it also depends on the language one uses:

american english(?): boat lean - body lean
american english: J-lean - bell-buoy lean
english: edging - leaning

See this picture too:
http://www.xs4all.nl/~dbarends/lln.gif

Personally I prefer to use the word 'leaning', because it is easier
to understand what is meant by leaning (to the) right or left,
where edging (to the) left or right gives more room for misinterpretations...
as I have noticed.
Also, in the Netherlands at least, edging right is leaning left, and vice versa,
and that makes it even less desirable to use those words together indeed
to avoid confusion!
Luckily the boats and the water don't care about it at all,
and only know a right or wrong way to do it ;-)

I make the distinction precisely because i want to be able to use the
terms differently. So that I can say to a beginner, for example, "Don't
lean, edge the boat" Unless I'm teaching a low brace turn, which is
leaned, by my definition.

Also, in the Netherlands at least, edging right is leaning left, and vice versa,
and that makes it even less desirable to use those words together indeed

So, you always say "lean" (or "leun"), but then add "boat" or "body" to
the front of it to make your meaning clear. That should work I like my
way better, but I wouldn't want to talk you out of yours. The important
thing is consistency. If "lean" can mean two things, saying "Lean!" is
ambiguous. "Lean the boat!" isn't.

http://www.paddlermagazine.com/issues/1999_2/Skheel.htm


Note that Mark uses the terms "boat lean" or "J-lean" a couple of times
initially, then abandons the word and uses "heel" for the rest of the
article. That's consistent with the way he teaches in person, IIRC.

Yes, but since I prefer a 'boat lean" (edging) over a "body lean"
in most situations,
when I am certain that it is clear that I mean a "boat lean",
I just say 'lean' (right or left).
Although I am well aware that for some kind of boats (very/too stable ones)
and situations, to get enough "boat lean", more or less "body lean" is
unavoidable though. In that case, the ability to brace (recovery in the UK?)
is certainly required, in my view and experience...

Pople are getting a bit too bitchy with each other for my liking, and a
bit too technical for my liking.

If you're in a long boat edge away fom the direction you want to turn;
if you're in a short boat edge toward the direction you want to turn.

Or, to avoid confusing the dutch: if you're in a marathon boat and want
to turn left, put all your weight on your right bum cheek.

Bitchy? Moi? I thought this was a very respectful exchange of views.
Technical? Well, only if you don't care why it works.

If you're in a long boat edge away fom the direction you want to turn;
if you're in a short boat edge toward the direction you want to turn.


That pretty much sums it up for me.

Yet another way to put it. Thanks.

That's a bit too, errr, /wrong/ for my liking. While it's true for
a carved turn, if I try and break into a strong tidal flow in a 5m
sea kayak using that advice then I'll get very, very wet and very,
very fast.

Long boats can be edged either way, according to the sort of turn
you make and the conditions you do it in.
