4.5.2 Creating
Routes
To create a route, decide the route number and select the waypoints to be used as way points in
order.
The same waypoint cannot be selected in a continuous manner.
Up to 20 routes can be created.
Up to 50 waypoints can be set on each route.
In addition to waypoints, the following items can be set for each route.
(1) RADIUS:
The arrival circle radius can be set.
(2) WIDTH:
The port and starboard route widths can be set.
(3) PLAN SPEED:
The planned speed can be set.
(4) GC/RL:
The distance calculation method can be set.
GC: Distance is calculated using the great circle method.
RL: Distance is calculated using the rhumb line method.
(5) STATUS:
You can set whether the waypoint will be use or not.
USE: The waypoint is used.
SKIP: The waypoint remains on the route, but is skipped.
Great-Circle Sailing (GC): The shortest distance from the current position to the waypoint can
be used, but the bearing will be different from that determined on nautical chart, and will
change during movement.
Rhumb line Sailing (RL): Sailing can be performed directly from the current position to the
waypoint, without changing bearing.
The ship bearing will match that obtained by drawing a straight line on a nautical chart
between the current position and the waypoint.
Great-circle sailing is generally used for long distance sailing, and Rhumb line sailing is used
for relatively short distance sailing.
