Todd,

1.  A standard main goes where you put it in general.  You raise it on =
the halyard, typically as far as it will go, then pull the goose neck =
down with the downhaul.  Within limits if you don't raise it all the way =
you can pull the gooseneck lower.  Typically you would reef the foot of =
the sail, leaving the gooseneck where it is.  On the IMF the whole sail =
assembly (furling tube and boom) can slide up or down the mast.  There =
are two pin positions (one hi for clearance of the pop top and heads in =
the cockpit, the other lower).

2.  The leading edge of the rudder is forward of the pivot line when it =
is fully down.  This makes the rudder a "balanced" rudder, as water =
pressure on the leading edge helps you with steering effort.

BTW, lee and weather helm are easy to remember.  If you let the tiller =
go and the boat heads into the wind, you have weather helm.  If you let =
go and the boat turns away from the wind, you have lee helm.  It has no =
bearing on where you are sitting.

  David, or Anyone,

       Again, the newbie has questions.  Two questions arose after =
reading your letter.

  1.   My boat is an older model and the goose neck is free =
floating....and has no "position".  What method of positioning the boom =
do newer boats have?

  2.    This question is more important because I was going to be making =
a new rudder.   The previous owner had made the one on there now.   The =
rudder actually pivots down so far that it goes slightly past vertical =
and starts to angle foreward.  Is this by design?

  Todd

  Joe, the weather helm you are experiencing is most likely due to the=20
  heeling. When the hull heels its geomtry relative to the water changes =

  inducing whether helm. The is acutally a good thing, as when the rig =
gets=20
  overpowered, the boat will autmatically tend to head up and luff the =
sails.=20
  On my boat with moderate wind I can sail the 175 all the way out (full =
main=20
  of course) and if I can keep her from heeling too much she is well =
balanced.=20
  The amount of wind you can do this in will depend on your "movable=20
  balllast". As you reef the jib, you should match with reelfing the =
main.=20
  Many on the list will reccomend lowering the boom to the lower =
position as a=20
  first reef. This will lower the COE of the main, but as the jib is 2x =
the=20
  size of the main, its benefit is small.=20
  Obvious, but also check to make sure the rudder is all the way down =
(leading=20
  edge actually ahead of the pivot line).=20
