1. Sailcomp Features
The Sailcomp 103AC is very straightforward in its operation. The junction box con-
trols
on/off
, the
damping
and the
light
. The remote keypad has five buttons which
control the system's 5 modes:
Trend Mode, Off-Course Mode, Nav Repeater Mode,
Head/Lift Mode
and
Starting Timer Mode.
Port
and
Stbd
: The
port
and
stbd
buttons are for the
Head/Lift Mode
.
They are used to enter your port and
starboard tack averages for racing.
Nav:
When connected to a NMEA 0183 navigation unit such as a loran or GPS, the
nav button turns your Sailcomp 103AC into a loran or GPS repeater. Once connected
to a loran or GPS, pushing the nav button makes the Sailcomp 103AC go into
Nav
Repeater Mode
. The display will alternate every 2 seconds between Bearing to
Waypoint and Distance to Waypoint in nautical miles. Cross Track Error is shown in
.05 nm increments to port or starboard on the upper part of the display.
Note:
If the Sailcomp is not connected to a loran/GPS, if the loran/GPS is not ON, or if way-
points are not entered into the Loran/GPS, the Sailcomp 103AC display will display "- - - "
when the
nav button
is pushed.
Timer:
The
timer button
puts the system into
Starting Timer Mode
and displays the
time remaining until the start of a race.
Crs
(Course): The
crs button
serves two main functions. It sets the course that you
want to use as a reference for the off-course indicator and it also allows you to change
between
Trend Mode
and
Off-Course Mode
.
2. Damping Control
The
damping knob
on the junction box controls the averaging period over which the
compass displays information. Damping does not diminish the accuracy of the
Sailcomp 103AC like it does in a conventional compass. The damping levels range
from 1-4, with damping 1 a nearly instantaneous readout and damping 4 about 14 sec-
onds of averaging. On most boats, damping 2 or 3 is the most stable and responsive.
If you are in rough seas, you may want to increase the damping so that you get a more
stable display. In calm water or at lower speeds, you may want to decrease the damp-
ing so that the display responds more quickly.
