Cruise NavigationFour separate and distinct
elements
  • Rhumb Line (RL) is the future course we intend to
    sail, and this should be plotted prior to the
    cruise to enable proper inspection and evaluation
    of the intended track and potential hazards and
    opportunities that may exist.
  • Dead Reckoning (DR) is a historical record of
    courses actually steered and distances traveled,
    which tell us our approximate position and
    provide a basis for using and evaluating other
    navigational data.
  • Verification is the process of improving our DR
    plot by adding other data and observations
    including LOPs from visual bearings, depths,
    radar, celestial and RDF currents leeway and
    other information.
  • Analysis is the examination of your route
    progress as compared with your intended track and
    destination in order to evaluate progress
    actually being made and to consider the effects
    of changing weather conditions, time schedules,
    boat and equipment condition, crew condition and
    other pertinent factors.
