Re: Spade rudders vs blue water passage making
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.
A pintle hung rudder (shafting) by its 'structural beam configuration' is FOUR times stronger than a cantilevered spade rudder .... size for size, that is ....; and yes indeed, they too sometimes fall off, usually as a result of NO inspection/maintenance of the attachments.
