A data field at the top of the page will now display the bearing and distance
to the second route waypoint. To continue, let’s enter a speed for our vessel,
which we can do from the ‘Setup Simulator?’ listing on the options page. The
setup simulator page is also available from any other page in the main page
sequence.
To enter a boat speed:
1. Press the O key to display the map options page.
2. Use the R keypad to select the ‘Setup Simulator?’ option, and press T.
3. Once the setup simulator page appears, press T to access the SOG field
(Speed Over Ground).
4. Use the R keypad to enter a speed of 60 knots.
5. Press T to finish, and J to return to the map display.
Once a speed has been entered, you’ll notice that the map will begin to move
slowly, keeping your boat centered on the display. To get a better view of what’s
going on, zoom in to a closer map scale.
1. Press the DOWN arrow of the R key to select the 16 nm scale.
You’ll now have a clearer picture of the route we are navigating, along with an
outline-only presentation of the surrounding shoreline. Because the usable range
of the built-in database is only valid to 64 nm scale, we no longer have full
cartography available. Keep in mind that whenever you do exceed the usable
range of the built-in database or the G-chart cartridge in use, the range field will
display ‘OVR ZM’ or ‘NO MAP’ to indicate that you should exercise extreme
caution using the cartography data. (See pages 31 and 72 for more information
on map scales and using G-chart detailed cartography.)
Now that we’re zoomed in a little closer to our route, we can pan ahead of our
vessel with the cursor to review and create on-screen waypoints and navaids. Try
moving the cursor to select the ‘TOUR3’ waypoint— just use the R keypad to
move the cursor as close as possible to the waypoint. (To move the cursor in
small increments, try a series of short key presses.)
