(Last time I checked) This may sound like a really stupid question, but I honestly don't know the answer. Is it easier to manuever a boat with twin engines with two rudders? What would be the difference if it had one rudder? Or if you have a single engine and two rudders? I am not sure I understand your question, but a single engined boat like the GB has one rudder, a twin engined boat like the Navigator has two rudders. On a power boat, the rudder is placed directly behind the prop(s) and it's purpose is to direct the prop wash to move the stern and provide steerage. It's not the same as a sailboat that would have a much bigger rudder and depends on the movement of the boat to steer, rather than the prop wash. Eisboch But you already knew that. Not all. the Titanic had 3 screws and one rudder. Was a major reason that it crashed after the short warning of the iceberg ahead. They tried to stop the ship and when the engines went to reverse, there was no steerage. Small rudder and no real flow over it. Huh? Eisboch |
