Caring for Oars at Commercial: –

  • Oars are expensive!  A pair of ultra-light ‘croker’ sculling blades can cost €800.
  • The oar tips are prone to breakage if not cared for.
  • Rowers should consult their coach to ensure they are using oars that are allocated to their specific squad.   Some oars are privately owned, but not marked correctly.  Always put oars back in the rack that you found them !
  • Never close the bay doors without first checking that the oars are in (otherwise high water could wash them away if they’re left on the slip).
  • Each year, after the end of the regatta season, the coach will ask his/her rowers for a few hours of their time to help paint and maintain the oars.
  • Always carry the oar with spoon facing ahead of you.
  • It is wise to clean oar handles on a regular basis.  Similarly, washing your hands before and after a session will minimise blisters, corns and calluses.
  • Please report any oar damage to your coach or log it in the red-book in the Gym.


Oar Parts and Terminology: –

Blade/Spoon: Flattened, spoon-shaped (macon) or cleaver ( Flat/Smoothie) shaped end of an oar or scull; often used as a term for an oar.

Button: Plastic sheath on an oar to prevent the oar from slipping through the rowlock; adjustable on modern oars.

Collar/Sleeve: Sleeve round the oar to fix the button; makes it easier to move the oar in the swivel

Handle: The part of the oar that the rower holds.

Inboard: The distance between the far end of the handle of an oar or scull and the face of the button. The remainder is called the outboard.  Your coach can advise you on the best inboard length.

Loom/Shaft: Connects the handle to the blade, gives us the length of the blade.

Oar: The lever used to propel the rowing boat, usually numbered to correspond to the seat number of the rower using the oar.

Outboard: The distance between the end of the centre of the blade on the oar to the face of the button; the remainder is called the inboard.

Sculls: A pair of oars for sculling boats (singles, doubles, quads, see our categories page).

Sweep: Long oars with narrow blades (pairs, fours, eights).  One oar per rower in a boat of 2, 4 or eight rowers.

Vortex Edge:  The Vortex Edge improves blade efficiency by decreasing slip in first half of drive, which in turn increases resistance and increasing slip in last quarter of the drive, which has the positive effect of decreasing backwatering.  The Vortex Edge provides an additional benefit of protecting the blade edge from wear or impact damage.
