Steve Zimmerman's espouses the virtues of an articulated rudder in his latest column "The Right Stuff"
It’s a simple problem, though not an easy one to solve: How do you allow a 2-inch-diameter propeller shaft to penetrate through the bottom of your hull, give it enough freedom to spin over 1,000 times a minute, yet not allow water to pass through the hole?
Let’s imagine that the boat has been hauled, and a dozen or so blisters can be observed. How do you determine the severity of the problem? Should you walk away, or perhaps renegotiate in hopes of lowering the price?
