Centerboard control lines

 The fiberglass tubes shown in the last post will be bonded in the locations that are pictured here in the drawing as blue and red dots.  The RED line is the pull up line and the BLUE line will be the pull down line.   The lines are guided upwards through two sheaves that are mounted inside the upper portion of the centerboard case. From there, they will continue upwards through the deck, through rope clutches to be managed by the turn of a winch.
