To provide a rudder plate and a vessel capable of demonstrating performance according to a situation.SOLUTION: A rudder plate 20 is capable of switching between a first state with an end plate 40 stored in a vane 30 and a second state with the end plate 40 expanded from the vane 30. Rudder force of the rudder plate 20 is capable of being increased in a state with the end plate 40 expanded and increase in resistance force by the end plate 40 is capable of being suppressed in a state with the end plate 40 stored in the vane 30. Therefore, when a performance required in the rudder plate 20 differs according to the situation, the rudder 20 is capable of corresponding to each situation by switching between the first state and the second state.SELECTED DRAWING: Figure 3

    【課題】状況に応じた性能を発揮することができる舵板及び船舶を提供する。【解決手段】舵板20は、端板40が翼部30に収められた第1の状態と、端板40が翼部30から広げられた第2の状態と、を切り替えることができる。端板40が広げられた状態では、舵板20の舵力を増加することができ、端板40が翼部30に収められた状態では、端板40による抵抗力の増加を抑制できる。従って、状況によって舵板20に求められる性能が異なる場合に、舵板20は第1の状態と第2の状態を切り替えることで、各状況に対応することができる。【選択図】図3
