RC Propeller BoatA propeller makes an aircraft, ship, or submarine in water or air go by making a big wind or a strong stream. It does this by turning two or more wings very quick. The blades of a propeller act as rotating wings and produce force through application of both Bernoulli's principle and Newton's third law, generating a difference in pressure between the forward and rear surfaces of the airfoil-shaped blades.

Paddlewheel BoatThe paddle wheel is a large framework wheel. The outer edge of the wheel is fitted with numerous, regularly spaced paddle blades (called floats or buckets). The bottom quarter or so of the wheel travels under water. An engine rotates the paddle wheel in the water to produce thrust, forward or backward as required.
