If the spread is increased to compensate for headwinds, what happens to the oar inboard length?

• A. The inboard length shortens
• B. The inboard length lengthens
• C. The inboard length stays the same
• D. The change cannot be determined

Answer: (A)

Increasing spread changes the geometry of the oar inside the boat. When you widen how far apart the oars are at the oarlocks, the inside end of the oar tends to sit differently relative to the blade and the water, which can alter the blade’s depth at the catch. To keep the blade entering the water at the same consistent depth and angle—even with a larger spread—you shorten the portion of the oar inside the boat. This adjustment brings the handle closer to the oarlock and reduces the inside lever, helping the blade maintain the right position to bite efficiently in headwinds.
