What's the advantage (or advantages) of a bent-shaft canoe paddle?
I've been told that it allows for more efficient use of both arms: the rationale I heard was that your arm on the grip does more work than your arm on the blade with a straight paddle and this is "evened out" with a bent-shaft paddle.
I've also been told that it moves the water more efficiently (though, assuming the same blade, I fail to understand the theory here.)
I'm neither a kinesiologist nor a physicist, so I'm not convinced about either of these answers. I find a bent-shaft paddle more comfortable, but I've always chalked that up to personal preference more than anything else.
Can anybody shed some light on this?
