After the J-Stroke this should be the next stroke to master. The sweep stroke is simply a wide sweeping of the paddle to create a turning effect pushing the canoe away from the paddling side.
So… How do you sweep?
Begin with the paddle as far as possible, sometimes I lean forward to get as much turn as possible in one stroke. Twist the paddle so that its driving face is turned away from the boat. Now sweep the paddle out as wide as possible, keeping the driving face pushing against the water. At half way round your lower arm should be fully extended, then continue pushing round passed the waist keeping fully extended, completing a semi-circle. Then take the paddle out and sweep again. This is a great stroke, it is very adaptable, how far round you sweep and how hard you push will vary the amount of turn. You can spin canoe around 180 degrees with one stroke or with only a small part of the stroke a small correction can be produce as you paddle along.
