Marine propulsion is the act of moving a floating object over or through water. Propulsion devices can take many forms including: propeller
Propeller

A propeller is a type of fan which transmits power by converting rotational motion into thrust. It can be used to drive an fixed-wing aircraft, ship, or the fluid within a pump....

Paddle wheel

A paddle wheel is a large wheel fitted with paddles which is used to propel a boat. Paddle wheels powered by steam engines were the means of propulsion for the paddle steamers of the nineteenth century when the technology reached the height of its popularity, but paddle wheels powered by other means were apparently known about long before,...

Sail

A sail is any type of surface intended to generate thrust by being placed in a wind—in essence a vertically-oriented wing. Sails are used in sailing....

Paddle

A paddle is a tool used for pushing against liquids, either as a form of Marine propulsion in a boat or as an implement for mixing....

Magnetohydrodynamic drive

A magnetohydrodynamic drive or MHD propulsor, is a method for propelling seagoing vessels using only electric and magnetic fields with no moving parts, using magnetohydrodynamics....

Ship

A ship is a large watercraft that floats on water. Ships are generally distinguished from boats based on size. Ships may be found on lakes, seas, and rivers and they allow for a variety of activities, such as the ferry or cargo ships, fishing, cruise ship, Coast guard, and warship....
