Sculling [SEP] Introduction
Sculling is the use of oars to propel a boat by moving the oars through the water on both sides of the craft, or moving a single oar over the stern. A long, narrow boat with a sliding seat and rigged with two oars per rower may be referred to as a scull, its oars may be referred to as sculls, and a person rowing it referred to as sculler. Sculling is distinguished from sweep rowing, whereby each boat crew member employs a single oar, complemented by another crew member on the opposite side with an oar, usually with each pulling an oar with two hands; and from stern sculling, which uses a single oar to propel a vessel with side-to-side movements from the stern.
