[Paddlewise] paddle sizing heresy

Had a little conversation with George Gronseth today. One of the benefits of
teaching for him is that I get to ask as many questions about kayaking as I
want. I have to admit some lack of education on proper paddle sizing as far
as euro-style paddles are concerned. I always use a Greenland stick, because
they are so much fun compared to white-man's paddles.

Anyhow, what I learned from George makes a lot of sense to me at least,
though undoubtedly many on this list will think it heresy. :)

#1 Only the paddle shaft length is important, not the overall length of the
shaft plus blades.
#2 The proper shaft length does not depend on the size of the paddler at
all, but rather on the size of the kayak being paddled.

The reasons for this has to do with the catch phase of the stroke. Too short
a paddle will cause the side of the kayak to interfere with the catch. This
will cause the stroke to initiate with some fraction of power wasted because
the catch starts further back. Unfortunately, the initial catch is where the
majority of the paddle stroke power is generated. Thus a lot of power is
wasted if the paddle shaft is too short. I experienced this when I paddled
with a 200cm whitewater paddle some time back. The blade would bump into the
deck, severely limiting the most useful part of my stroke.

Blade size does not matter, because as Matt Broze said earlier, water is a
heavy fluid and even most small blades hardly slip through the water.

Paddler size does not matter much... not when compared to kayak beam and
deck height. These factors dominate over paddler size, because they dictate
how long the paddle shaft should be.

According to George, the best way to determine proper paddle shaft length is
trial and error. Try several different paddle shaft lengths, and determine
which one gives you just enough clearance over your deck. Once clearance is
achieved, any extra length is only a disadvantage because of the slower
stroke cadence (and other reasons).

None of this applies to a Greenland style paddle, because that is a totally
different animal.

One other bit of George wisdom, which is one of the first things he teaches
in his classes... Feather angle does not matter at all. Just pick one, and
stick with it.

Cheers,
Kevin
