Avon Prindle 15 - Section II: Sailing; Sail Trim to Weather

Tum the boat until the wind is blowing from a 45°
angle to the bow. Ease the traveler out to the lee side
and sheet the main
in tight. Have your crew sit on the
trampoline to keep the mainsheet from uncleating and
the boat from tipping. With the main sheeted to
leeward, the leeward shroud
will be loose. Move the
shroud down a couple of holes on the adjuster, but not
all the way down. Replace clevis pin and ring. Loosen
mainsheet.
Tum the boat so the wind is coming from the
opposite side. Ease the traveler out to what
is now the
lee side .
and sheet in. The new leeward shroud will be
loose. Move the shroud down to the corresponding
hole
in the adjuster as the first shroud. If the rig is still
loose, move the shroud down
one or two more holes
and repeat with the other side until the
rig is fairly tight
and both shrouds are
in the same hole on adjuster.
It is possible to over-tighten the rig which will make
the mast hard to rotate.
When you take the boat apart, be sure
to loosen
one side only before taking the main down. By
leaving one shroud in the correct hole, you will only
have to tighten
one side next time you go sailing.
If you are not happy with the mast rake you have,
simply lengthen or shorten the forestay turnbuckle.
Be
sure to leave at least 10 complete threads into
each side of the barrel.
Section II:
SAILING
SAIL TRIM
To Weather
The main traveler should be centered with the main
and jib sheets in snug. Be careful not to pull the sails in
too tight. If the main is oversheeted (too tight), the
mainsail
will be too flat and the boat will not move very
fast
If the jib is oversheeted it will stop the air flowing
between
the leech of the jib and the mainsail. This gap
(slot) between the jib leech and
the mainsail should be
about
12 inches near the top of the jib.
The jib tell-tale on the leeward and windward sides
should be streaming back.
If the windward tell-tale on
the jib is flopping forward you should head the boat
downwind a little.
If the leeward tell-tale is flopping
forward, you should head the boat up into
the wind a
little or,
if you do not want to head up any further, let
the sail out a little.
