Galley Propellers are a type of propulsion system used in boats and ships. They consist of two or more OARS, which are long poles with blades at one end that are used to move the vessel through the water. OARS are the most common form of propulsion for small boats and canoes, but they can also be used in larger vessels such as galleys. Galley Propellers are an efficient and cost-effective way to propel a boat or ship, and they are often used in combination with other forms of propulsion such as sails or motors.
