Raising the oar blades high off the water during the recovery, especially just before the catch. This delays the catch (bad) and makes the shell very unstable at a point in the stroke when your center of gravity is highest.

The incorrect action of carrying the hands too low during the recovery, especially when the rower dips his/her hands just prior to the catch (i.e. sort of winding up).  This action usually results in the blade being too high off the waterâ€(tm)s surface.

Term used to describe a blade that is too high off the surface of the water during the recovery.

Catch with the blade only skimming the water, or holding hands too low during recovery so that blade is too high off the water's surface.
