Now that the greenland paddle heat has cooled (I hope) some, maybe I can 
get some of the scientific minds to answer a small question.

I, as most of you know?, paddle folding boats and use stock, break apart 
paddles. Nothing fancy, altho after joining this list I have cut down one 
of my plastic paddles to relieve the pressure on my ageing joints.(seems 
to work) Most of this heated debate has been interesting, even if very 
confussing! I would guess paddles were like bows. They used the style 
that suited the purpose. ie, the short bows of the plains indians because 
of the horse...Modern man uses them ones with training wheels because he 
likes to cheat(he thinks)and like to tinker.(I guess this is for anouther 
site tho) :>)

My question. I have noticed the twin little vortex swirls coming off the 
edges of my paddles from time to time and under certain 
circumstances(while backing out of a tight cove)I have noticed that these 
darn things can spin on seemingly forever. (I watched one spin for I know 
a solid minute, and would have went longer except I stuck my finger in 
it)
Where does these things get their energy to keep spinning? I find it hard 
to believe that they are kept spinning on the paddle stroke energy. 

Maybe not important in the world of high pressure paddling, but it darn 
sure is in my world of laid back paddling.

Thanks.

James

 Not so quick. I did a little scientific experiment this weekend while
paddling down the St. Marys river. It was low do to not much rain from the
rain Gods no matter who we have sacrificed to try to appeased them.
Any how back to my observations. My paddle stroke with my greenland paddle
is about 2 ft. While paddling many miles of 8-10 inch water over white sand
I watched my stroke. Yes the boat did move forward but my paddle slide back
4-6 inches each stroke . Now my mind isn't all that scientific after
spending 12 years in the 5th grade I finally did graduate. About a forth of
my stroke was slippage, I watch the big blade paddlers but could not make
any sense of it their paddles keep hitting the sand. My stroke was normal
even though I was in shallow water. Now what do all of you learned minds
make of this? anything to it or did I just pend a lot of time watching my
paddle instead of the logs and trees that I ran into along the way in this
experiment?

It sounds as though a pole may have been more efficient : )Fred

Wow!!! I have an excuse to do another experiment! Any particular diameter ?
I have heard of some canoe guides up north some where using poles to paddle
with and they do pretty good if what I hear is right, a little slow to get
up to speed but nothing new there if you use a Greenland blade .
