Chapter 6 - Understanding the Waypoints Function

Introducing waypoints

The term waypoint refers to a point (a location) that you’ve entered into the 958’s memory. The waypoint appears on the chart with the symbol you’ve chosen. In contrast, the term nav aid refers to a point that’s permanently stored on the

Navionics chart cartridge.

Here are some of the functions you can perform with waypoints:

• go to a point on the CHART screen in one step (making a

“quick” waypoint)

• store waypoints into the 958

• go to these waypoints

• string these waypoints together to form routes

• follow these routes

• edit or erase waypoints or routes

• plot waypoints or routes

•

• transfer all waypoints (and routes) between any two 958’s transfer waypoints (and routes) from the 958 to a PC, and back again

Displaying waypoints

You can display waypoints in any of four ways:

•

• A graphic (chart) view of waypoints

A list of up to 30 local waypoints, sorted by nearest first

•

• A list of all waypoints, sorted alphabetically

A list of up to 30 local avoidance waypoints, sorted by nearest first

First, press the WAYPTS/ROUTES key, then the WAYPOINTS menu key. To view the LOCAL, ALPHA, and AVOID waypoint lists, press the NEXT VIEW menu key. The 958 displays the type of list at the top of the screen. Each press of the NEXT

VIEW menu key cycles through the waypoint viewing list in
