Introduction
The Duffek Stroke is often used to quickly peel out of an eddy into fast moving water. Instead of simply blasting our way out and across the river, in some cases we want a very tight escape and turn downstream. This technique uses a stationary draw stroke. Here is a very detailed explanation of the technique along with a demonstration: Duffek Stroke. In this demonstration, a gliding bow draw is used to escape an eddy in whitewater: Gliding Bow Draw.
The Boof Stroke
The boof stroke is really an advanced move to ski jump over obstacles like holes or to flat land your kayak in places you really don't want to pencil in or piton. I am including it here since it is often mentioned on paddle club forums and is often combined with a draw stroke to make last minute corrections: The Boof Stroke.
