Is there slop in the centerboard
Do you need all those adjustment holes in the side of the centerboard?
Does it go straight up and down, or is it warped?
Are the centerboard and skeg in line?
Are the foils smooth and fair?
How is the centerboard travel, does it reach maximum dept without
exposing the top notch? (Marking the board with a pencil best performs
this test, with the boat is in the water.)
Is the rudderpost and steering head tight?
