If your oars are too long or hard to pull, they may not clear the water on the backstroke. Oars that are too short won’t dig into the water or allow the rower adequate leverage. Narrow-beam boats and low-freeboard boats require shorter oars.
Basic Rule for Sizing:
1/2 beam (distance between oarlocks) x 3 + 6" = oar length
| Beam At Oarlocks | Recommended Oar Length |
|---|---|
| 3'4" | 5'6" |
| 3'8" | 6' |
| 4' | 6'6 |
| 4'4" | 7' |
| 4'8" | 7'6" |
| 5' | 8' |

Oar Sizing FAQ:
What happens if I use oars that are too short for my boat?
If your oars are too short, they won't provide enough leverage for effective rowing, meaning you'll need to exert more effort to propel the boat. Additionally, shorter oars may not dig deep enough into the water, resulting in inefficient strokes and slower movement.
How does freeboard affect oar length?
Freeboard, the distance from the waterline to the top of the boat's side, impacts how high the oarlocks are above the water. Boats with low freeboard may require shorter oars to prevent awkwardly high rowing angles and to make it easier to keep the blades in the water for effective propulsion.
What factors should I consider when selecting oar length for a tandem rowing setup?
For tandem rowing (where more than one person rows), it's essential to account for both the beam at the oarlocks and the rowers’ synchronization. Oars should be long enough for proper leverage but short enough to avoid interference between rowers, especially in narrow boats.
Can oar materials affect the rowing experience?
Yes, oar materials can significantly impact performance. Wooden oars provide a traditional feel and are durable but can be heavier. Composite materials like carbon fiber or fiberglass are lighter and more efficient, reducing fatigue during longer rows but may be more expensive.
How can I ensure the correct rowing technique with my oars?
Proper technique involves ensuring that the blades are fully submerged during each stroke without the handles hitting your body. Adjusting your grip width and arm position will help maintain a consistent stroke while avoiding splashing or skimming the water surface. Correctly sized oars make it easier to maintain this form.
What can I do if my oars don’t fit the recommended sizing formula?
If your oars don’t match the recommended sizing, you can adjust the oarlocks or experiment with different rowing angles. Some rowers also choose oar extenders or adjustable-length oars to fine-tune their fit, ensuring comfort and efficiency despite not following the standard formula exactly.
