Rowing Prop is a term used to describe an OAR, which is a long pole with a flat blade at one end that is used to propel a boat through the water. It is typically used in rowing, a sport where one or more people use oars to move a boat across a body of water. The OAR is held in place by a rowlock, which is a device that attaches the OAR to the boat. Rowing Prop is also used to refer to the person who operates the OAR.
