oarshaft

An oarshaft is the central, long portion of an oar, extending from the handle to the blade. It functions as the lever that transfers the rower’s force into the blade while connecting to the oarlock or rowlock. The oarshaft is distinct from the blade, which sits in the water, and from the handle at the end of the oar.

Construction and materials: In traditional boats, oarshafts are carved from a single piece of hardwood such as ash or beech and shaped to a gradual taper for strength and lightness. Modern oars frequently use laminated wood or composite materials, including fiberglass and carbon fiber, which reduce weight and can increase stiffness. Some oars are built as two- or three-piece assemblies, with the oarshaft detachable for easier transport; in these designs the shaft may be divided into a proximal part and a distal part joined by a lock or sleeve.

Shape and fit: The shaft is typically cylindrical or slightly oval in cross-section and may be tapered along its length to optimize flex and balance. The inner end of the shaft connects to the blade via the loom and is aligned to fit into the boat’s oarlock or clamp.

Maintenance and context: The oarshaft is a critical load-bearing component and is inspected for cracks, splits, or delamination. Wooden shafts require conditioning and protection from moisture, while composite shafts require attention to impact damage and delamination. Oarshafts are used in both sweep rowing and sculling, with sizes chosen to suit rowers’ height and boat class.
