4.2.3 How to create a route with the Easy Routing feature
The Easy Routing feature automatically constructs a route between two points, taking
into consideration the preset values for safe depths, safe heights and boat’s width, to
provide you with an estimate of a safe route to your destination. Easy Routing can be
initiated on points, on quick points, on track points, on route legs, on a position fix, on
MOB position, on DSC points, on a cartographic object, and chart.
You simply set a start position and a destination. This can be newly entered points or
any of the points mentioned above that are currently on the screen. (The total distance
can not be longer than 100 NM.) Easy Routing then analyzes the path between the
two points and creates a route, inserting legs in the route when necessary to get you
away from areas which exceed the safety values set on the menu. Easy Routing an-
alyzes each leg for safety in three levels: safe leg, potentially dangerous leg, and un-
safe leg, and color codes them accordingly, green for safe, yellow for potentially dan-
gerous and red for unsafe.
Note: A chart card must be inserted to use Easy Routing. Not all chart cards carry
Easy Routing. The message "No charts with Easy Routing data found." appears if a
chart card does not have Easy Routing.
EASY ROUTING DISCLAIMER: The accuracy of Easy Routing is limited by the avail-
ability of electronic charts loaded on your navigation system and the accuracy of orig-
inal source material used in producing such charts. Always remember that you should
navigate with the most detailed and up-to-date chart available from FURUNO, and
new information from National Hydrographic Offices may render your charts obsolete
at any time. Easy Routing is only an aid to navigation and must be used in conjunction
with conventional navigation practices. As the navigator of your boat, you are respon-
sible for reviewing the suggested route against the official nautical publications and sit-
uational awareness. You must edit and/or approve the suggested route before using
it for navigation purposes.
