distance-behind-boat of an object. VRMs consist of a horizontal
(depth) line and a vertical (distance-behind-boat) line.
Your actual rate to a waypoint based upon your current speed and

Waypoints are locations or landmarks you save on the chart so that
you can return to them at a later time or place in series to create a
route. Waypoints can be stored in the system, archived to a Compact
Flash card or transferred to another NMEA compatible instrument.
