Re: Spade rudders vs blue water passage making
The culprit in this case was crevice corrosion on the stainless rudder shaft at the bearing. Not an easy spot to inspect. Even if it was hung on a bottom hinge too not sure it would have made a difference.
Perhaps not, but the forces exerted on a rudder are really substantial. Having a bottom hinge transfers the load down and splits it between all hinges. There are not many keel hung rudders that suffer from a broken shaft. Frankly, never heard of one.
Be kind, for everyone you meet is fighting a hard battle.
