11. CENTERBOARDS
The centerboards are spring loaded for
positive locating at desired positions and to
allow retraction if contacted from below.
11.1 When the handle is lifted slightly and
moved forward in the key slot, the board is free
to descend. Several adjustment knots can be
placed in the line to permit the boards to
extend to a variety of depths. When the board
is fully extended it should reach 19 1/2 inches
(49.5cm) as measured from the bottom of the
hull to the tip of the board. When the board is
fully retracted, the centerboard line should
measure 21 1/2 inches (51.6cm) from the deck
to the underside of the centerboard handle. To
raise the board, pull up on the handle and slide
the line into the key slot just below the last
figure-eight knot. (FIGURE 16)
