Full feather strokes, with a pause before the tap down at the finish. Blades should be rolled flat onto the water at the finish. After the pause, rowers should tap down and bring their blades off the water. Unlike Dragging Blades drill, should be no tap down at catch.
Progression
Can start by half boats, then progress to full boats. Also switch pause to every other, then every three, and finally go continuous.
Note
Boat should be very set at the finish, so this can be relatively safe in rougher water. Ensure blades are not coming off the water before the pause. Ensure there is a definite intention to tap down after the pause.
