oars (301 words)
The distance between the rear edge of the rower's seat and the rowlocks should be about the distance between the inside of the rower's wrist and the inside of the elbow.
An oar is a lever with its fulcrum at the oarlock.
So, for example, if the distance between rowlocks is 42 inches, the distance from the end of the handle to the button should be (42 ÷ 2, + 2 =) 23 inches, and the overall length of the oar (23 ÷ 7, × 25 =) 82 inches or 6 feet 10 inches.
