A female sculler at race pace of 8min for 2000m is travelling at 4.167 meters per second = 15 kilometres per hour.
The edge of the blade is approximately .25cm thick. To execute the perfect catch you need to catch the equivalent sliver of water, in a vertical down attack, as that sliver of water is moving away from the blade at 15klm per hour.
A recent study has determined the need for a Kilogram of power per scull handle is required to execute the catching of the water without missing a %, and thus kicking the boat backward.
The word attack is appropriate, the Italians use the Italian equivalent for the catch. The danger is to drive the blade too deep.
Practise-hand /foot co-ordination - feel and Deltoid lock at the correct depth of the blade, will counter-act too much depth.
