Red Settings Above = Base Settings

Light Air Set Up Guide (0-6): Loose headstay, ease all shrouds so leeward V1 is loose.   NO backstay, crew to leeward below.  Boom trimmed above centerline, top telltale flying 100%. Jib lead forward so mid foot hits life line, with a lot of twist.  Both sails should have wrinkles up the luff and the boat sailed at 10-13 degrees of heel.
Light-Medium Set Up Guide (6-10): Backstay is the first adjustment to control head stay sag.  The next is the V1 and the other shrouds.  The boom is now just below centerline with the top telltale flying only 50%.  Jib lead is moved aft and trimmed harder not touching the life line.  Crew up on the windward side leaning against cabin top.
Medium-Heavy Air Set Up Guide (10-20 True): Tighter shrouds and tighter trimming on all sails.  The crew is now hiking out hard and the boat should be sailing at target speed and angle.
Heavy Air Set Up Guide (20-28 True): Max tension in all shrouds and backstay.  Jib lead is aft and main traveler is on centerline.  The vang is pulled hard and the mainsheet is not the traveler.  Use the main sheet to keep the proper heel angle between 20-25 degrees.  Crew is hiking hard just aft of V1 shrouds.
