past echo position
To go directly to a past echo position (as long as the GPS is
providing position data):

The navigator creates a new temporary waypoint called
COORD and returns to the SOUNDTRAC screen. The
COORD waypoint isn’t stored in the waypoint database;
instead, it’s placed in the trip, where it replaces any future
trip points. To see this current waypoint on the CHART
screen, press CHART at any time. Your present vessel
position and time have now become a past trip point.
