Pronunciation: [ɹˈʌdəz] (IPA) 
The word "rudders" is spelled as /ˈrʌdərz/. The first syllable, "rud," is pronounced with the short u sound as in "mud." The second syllable, "ders," follows the usual rule for forming plurals of nouns ending in "s," pronounced as a syllabic z sound. Thus, the final sounds of the word are "derz." "Rudders" refers to the movable controls attached to the stern of a boat or aircraft used to steer it in water or air.
Rudders are an essential part of many watercraft, particularly boats and ships. They are primarily located at the stern (rear) of the vessel, and they are used to steer and control the direction of the craft.
A rudder typically consists of a flat or curved vertical surface attached to the bottom of the hull, extending below the waterline. It can be moved either manually or by a mechanical system called the steering mechanism. The rudder pivots around a vertical axis, allowing it to deflect the water flow and create forces that change the vessel's heading.
By angling the rudder to one side or the other, the captain or helmsman can alter the direction in which the craft travels, enabling maneuverability and navigation through water bodies. The rudder's size, shape, and positioning are determined by the specific type and size of the vessel, as well as the intended purpose and operational conditions.
Rudders are crucial for maintaining stability, balance, and control over the watercraft while underway. They help counteract external forces like wind, waves, and currents, ensuring the ship maintains its intended course. Additionally, the rudder aids in reducing the turning radius of the vessel, making it easier to steer and navigate sharp turns or changes in direction.
Overall, rudders serve as a vital component in the control system of watercraft, allowing captains to effectively steer and adjust the heading of their vessels.
The word "rudders" has its etymology from the Middle English word "rother" or "rotherfore", which originated from the Old English word "roðor" or "roðorfore". In turn, these words are derived from the Old Norse word "ruddra" or "ruddri", which meant "steering paddle" or "oar". Ultimately, the origin can be traced back to the Proto-Germanic word "ruþrōną", meaning "steering paddle".
