boat tiller

基本解释

A tiller is one way a sailboat's rudder is moved to turn the boat.
舵柄是转动船舵（rudder）来改变船的朝向的一种方式。
Tillers are more commonly used on smaller sailboats because it can take much force to move the larger rudder of a big boat with a tiller.
舵柄在小型船只上使用得更广泛，因为对于大船来说转动舵柄来掌舵需要太大力气了。
The boat turns in the direction opposite that in which the tiller is pushed: to turn right (to starboard), push the tiller left (to port).
船朝着与舵柄被推动的相反的方向转动：若要船转向右舷（starboard），将舵柄向左（port）推。
