Responder a: Razão de Guinada – Contradição do livro?

O PNA menciona que a estabilidade é mínima em profundidade de 1,5 o calado, o que dá quase no mesmo, pois faz com que o RoT seja maior em pequenos ángulos de leme (veja fig 102) .

“From the Esso Osaka trials, checking and counterturning ability were reduced as water depth decreased from deep to an intermediate depth (50 percent of draft as bottom clearance) and then increased at the shallower depth (20 percent of draft under keel). This phenomenon is related to an apparent reversal in controls- fixed course stability as shown in Fig. 102, where stability first decreases but then increases as water depth becomes very shallow.” pg 281
