Dinghy propellers are a type of propulsion system used on small boats, such as dinghies. They are typically powered by an outboard motor and are designed to provide thrust in order to move the boat through the water. The most common type of dinghy propeller is the oar, which is a long pole with a blade at one end that is used to push the boat forward. OARS are usually made of wood or metal and are held in place by a set of oarlocks.
