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