Balanced Helm

Joe,
&nbsp;&nbsp;&nbsp;&nbsp; There several ways to describe the same condition.&nbsp;
I have the same problem with understeer and oversteer when setting race
car suspensions up.&nbsp;&nbsp;&nbsp; Lee helm and Weather helm are as
simple to remember as their names.&nbsp; If you need to hold the tiller
to the weather side of the boat (side toards the wind)&nbsp; you have "weather
helm".

 As long as we are here, help me get it straight. I have a mental block
with
 lee and weather helm. If the wind is coming over the port side, I am
on a
 port tack. If the boat is trying to head into the wind, I. E. bow to
port,
 and I am sitting on the high side, the port side, and I am puling the
tiller
 toward me, I. E. trying to head the boat away from the wind to starboard,
 which is this lee or weather helm? Is the opposite true? If I was pushing
 the tiller award me, I. E. trying to head the boat into the wind to
port...
 I be confused.
 Also in light air, I am balanced. I have issues only as the wind picks
up,
 I'm trying to understand the dynamics. I know I need to roll in some
of the
 genny to stabilize the boat.
 Joe
 W/V/ Whisper

 Mary Lou, Joe, Et All,
 If you are having lee helm with the 175% genoa in light air, then consider
 trying the following before you lengthen the forestay:
 Slack off slightly on the mainsail's outhaul on the boom. This will
 increase the fullness or maximum draft in the mainsail's shape. In
light
 air, increasing the draft on the mainsail will power it up relative
to the
 genoa, which should move the sail plan's center of effort aft &amp;
thus
 decrease your lee helm. (&amp; make you go faster as well!) The downside
is
 that the new sail shape will be less forgiving of sail trimming &amp;
helmsman
 errors. i.e., the "groove" will be narrower.
 +
 Tighten up the mainsail's leech line. This will cause the mainsail's
leech
 to curve ("hook") to windward. This will cause the mainsail's center
of
 effort to move aft, which will decrease lee helm.
 +
 Make certain you are using the main sheet &amp; traveller properly.
Watch your
 mainsail's leech telltales to be certain you are not overtrimming the
 mainsail, thus causing the airflow to stall. If you stall the airflow
over
 the mainsail, the sail plan's center of effort will move forward &amp;
increase
 lee helm.
 +
 Make certain you are not overtrimming the genoa. The exhaust airflow
coming
 off an overtrimmed genoa will blanket the mainsail &amp; induce the
airflow on
 the leeward side of the mainsail to stall. See above bullet point
 If these techniques solve your light air lee helm issues; then, it
will be
 better than permanently raking the mast further aft, which will increase
 weather helm under all conditions. Remember, these sail shape adjustments
 are subtle &amp; a little bit of sail shape or sail trim change can
have a
 significant effect.
 Good luck!
