3.3.2 While Stepping The Mast (Fig. 3.3.1)
3.3.3 After Mast Is Stepped.
3.3.3.1 rake adjustment
Hang a weight such as a hammer or wrench from the main
halyard just below the gooseneck level. The fore and aft
distance between the halyard and the mast at the gooseneck
is the amount of rake.
NOTE: YOUR PEARSON IS DESIGNED TO HAVE THE MAST RAKED AFT.
SEE SAIL PLAN FOR SPECIFIC INFORMATION. THIS MAY BE VARIED
TO SATISFY THE PREFERENCE OF SAILMAKERS3 BUT FORWARD RAKE
SHOULD BE AVOIDED.
Adjust the headstay and the backstay turnbuckles (let off
on one3 take up on the other) until the desired rake is
achieved. Make certain that the lower shrouds and inter-
mediate shrouds are slack enough not to interfere with this
adjustment.
Pin the headstay and backstay turnbuckles.
3.3.3.2 side-to-side perpendicularity.
Ensure that the lower shrouds and intermediate shrouds are
slack enough so as not to interfere with the follow adjust-
ments.
Lead the shackle end of the main halyard to an identifiiable
point on the rail or chainplate. Adjust the halyard
tension so that the shackle just touches this point, and
then cleat the halyard.
Lead the halyard to the same location on the opposite side
of the deck, and check to see if the shackle touches the
same point with the same tension. If this is not the case,
let off on one upper shroud turnbuckle and take up on the
other to get the desired result.
With the mast centered transversely, tighten both upper
shrouds uniformly, one full turn on one side, then one full
turn on the other. Repeat until the turnbuckles become
properly tight. Pin and tape the upper shroud turnbuckles.
Tighten the lower shroud turnbuckles to a hand-tight condi-
tion, then sight up the mast to check for straightness.
Make appropriate adjustments to the lower shroud
turnbuckles if this is not the case, ie. if the mast is not
straight. Be sure to make equal and corresponding adjust-
ments on each set of turnbuckles (a one-turn take-up on the
port lower shroud should be followed by a one-turn easing
on the starboard shroud, etc.).
Pin and tape the lower shroud turnbuckles. Tape any
remaining pins.
