I spent about 4 hours cleaning up, edging, and shaping the rudder stock, rudder, and (partly) the leeboard. Back is sore now; working out is NOT the same!


Below is an approximation of the foil shape on the rudder; not NACA by any means, but sufficient unto the day!


I use a marker to indicate the centerline of all foils, and leave the thickness of the line on trailing edges. Avoids flutter caused by TOO thin a trailing edge and gives some strength to that thin edge as well.

Now I need to fill/fair pieces, cover both with 3oz cloth, and fiberglass tape leading edge and bottom of rudder.

Un Abrazo,

    Hi Bill, does D’Arcy Bryn have lead in her rudder? I have seen some builders of Jim’s boats put lead in the leeboard too, what do you think about such a strategy?

    Yes, there is lead in the rudder as in most Michalak designs. I have never used lead in any of my lee boards, but I do recommend a releasing jam cleat like Duckworks sells. I use it as a shallow water warning device! Time to come about!!
