Line navigation options in DelphNav

Steering a vessel along a predetermined line is a basic necessity of practically any survey
and a core function of any navigation package. In DelphNav, the Helmsman Display win-
dow (Figure 23) is a key tool for navigating a vessel along a line. This window provides
visual information on vessel distance off the selected survey line, start of line (SOL) EOL
distance, and heading direction from waypoint-to-waypoint and vessel-to-waypoint (for
correcting off-line deviations).
