Re: All broke up




We are building a kick up rudder blade to replace one that broke because the
foam inside did not cure. This is the first 23 rudder to break in nearly ten
years of building rudders. Clark used a structural foam inside, which seems
to fail after time. We use a lighter foam inside, and a stronger shell,
which results in a stronger blade. We will stand behind any of ours that
break in two years of sailing. Tire tracks on the blade void the warranty
