Get Bent

Background

There are lots of claims about the efficiency and wonders of Bent Shaft paddles - Shawn Burke probably makes the best case. Although I don't typically use one, unless I am on a longer lake 'cruise', I do agree that they do provide an increase in efficiency. The increased efficiency may mean a faster ride, more energy to spare at the end of a long paddling day, or a reduced chance of repetitive strain injuries. There are various claims on how much extra you can get out of a bent shaft but there is very little actual research to substantiate the claims (number range from 2-15%). The increase can translate to a few extra kilometres over a day of paddling, or a little increase in speed (maybe 1-2km/hr).

The consensus seems to be a bend of 12 degrees (although there is lots of discussion ranging from 10-15 degrees) provides the optimal touring paddle. The overall length of the paddle should be shorter than your 'normal' touring straight shaft paddle. Here again, there is lots of discussion, some people actually like a longer bent shaft paddle. My bent shaft paddle(s) is a little shorter overall, but the actual shaft length is about the same as my normal touring paddle.

How it Works

The bend angles the blade forward at the start (catch) of the stroke. This means during the most powerful portion of the stroke, for most paddlers, the blade remains more vertical in the water. The vertical blade presents a larger surface area providing more efficient transfer of power during the section of the stroke that pulls the canoe forward through the water. If you only have one bent shaft then give it to the bow paddler, their job is to paddle (an unthinking automaton). If you have two then sit-n-switch down the lake.
