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
