The Biomechanical Advantage of Height in Rowing

Question
Can you explain in biomechanical principles why a taller person has an advantage in rowing?

Answer
Hi George: Height is definitely an advantage in rowing. Longer limbs lead to a longer stroke cycle of the oar through the water.  Obviously, this is going to be more efficient than a shorter stroke in terms of moving a boat through the water.

Of course, it is not correct to assume that a 6'4" rower will always outperform a 5'8" rower.  If the shorter rower has better technique, strength and endurance (as well as intangibles such as determination through pain), he will move a boat better than the taller rower.  But if all these considerations are equal, the mechanical advantage of height will lead to a more efficient rower.
