Boats have COUNTER-ROTATING PROPELLERS: This is an example of an inboard vessel with twin engines. This is called a twin screw. Each propeller spins counter to one another when they are in forward. This mitigates what is called side effect. If both propellers spin the same way when in forward, the boat would drift to one side, causing the captain to need to correct steering often.#howtoboating #howto #boating #boat #yachting #yacht #driving #drive #props #right #left #inboard | How to boating

Contra-rotating propellers boost ship propulsion efficiency by over 10 percent compared to conventional designs.

More Contra rotating props - Keep it cranking 😂 Aircraft equipped with contra-rotating propellers, also referred to as CRP, coaxial contra-rotating propellers, or high-speed propellers, apply the maximum power of usually a single piston or turboprop engine to drive two coaxial propellers in contra-rotation. Two propellers are arranged one behind the other, and power is transferred from the engine via a planetary gear or spur gear transmission. Contra-rotating propellers are also known as counte
