Re: Full or fin keel?
My long fin keel or twin keel steel boats are anything but expensive for their displacement.
Many of those older , short keel with rudder attached boats have been drastically improved, by taking the rudder off the keel and replacing it with a skeg hung rudder six feet further aft. I did that on my first boat,a 36 ft pipe dream sloop, designed by Kinny , with a drastic improvement in control. A 1958 design with the same improvements has won the Shark Spit regatta for the last three years in a row. The owner said "If anyone does the same thing on an Alberg 37, I'll never catch him.
Well raked , short keel hung rudders tend to act as drogues.
