[C320-list] 130 jib sheet track placement

[Troy Dunn]

Mark has it nailed.   There isn't a single position.  It's a range of
positions based on apparent wind direction and speed.   The key is to learn
how to tell when you have proper sail shape and adjust the car
accordingly.  For a 130....the number three hole feels way too far back for
any conditions.   I don't think we use that hole on our 155 unless it's
blowing like stink and we are driving the rail into the water...which is
generally the 4th of Nevuary if the Admiral gets her way.   Over time you
will "get a feel" for where to generally position the car to get an ideal
shape for your point of sail and conditions.   Unless you are racing or
have one of those fancy pants Garhauer car adjusters...you will learn to
live with "good enough" and enjoy cruising...until another boat happens by
or God forbid...passes you...

FWIW-
