4. Head/Lift Mode
The Head/Lift Mode operates in a manner quite similar to the Off-Course Mode
except that it handles two reference headings simultaneously and the computer deter-
mines which of these to use.
To use the Head/Lift Mode, do the following:
1. Push either the
port
or
stbd
button. This first push puts you into the
Head/Lift
Mode
, but does not alter anything.
2. Before the start of a race, sail upwind on port tack for at least 10 minutes and
observe your compass reading. Determine what your average heading is over this
period. This heading becomes your
Port Tack Average
.
Sail on this heading and push the
port button
to store this heading as your port
tack average. Make sure the digital heading on the display is reading what you
consider to be your port tack average when you push the button.
Repeat the same procedure on starboard tack, and push the
stbd button
to store
your
Starboard Tack Average
.
When racing upwind on
port
or
starboard tack
, if you are sailing closer to the mark
than the stored averages, more upwind, this is called a
Lift
. If you are heading farther
away from the mark than the averages (more downwind), this is called a
header
.
These averages will be stored in memory, and if you are in the Head/Lift Mode, the
Sailcomp will know which tack you are on and will calculate whether you are being
headed or lifted and by how much. This information is sent graphically to the upper
analog section of the remote display. The words, "
HEAD
" or "
LIFT
" will also be dis-
played on the upper part of the display.
(This is a quick way to determine whether you are
in Head/Lift Mode or Off-Course Mode.)
Remember that everything you see on the upper bar graph on the remote display is
perceptually normal in terms of left and right. If you see segments to the right when
you are in any mode it means the same thing: you are heading to the right of your ref-
