  1. Welcometo the • United States Power Squadrons' • Chart Smart Seminar Piloting - Plotting a Course (Section 5)

  2. Section 5: Piloting - Plotting a Course Navigation vs Piloting Accuracy Standards Plotting Tools Hands-on Practice Class Agenda - cont'd

  3. Navigation The science of directing the movements of a boat from one place to another in a safe and efficient manner. Piloting A part of navigation using landmarks, navigational aids, and soundings as primary tools. Definitions You will need a chart, a compass and plotting tools

  4. 

  5. Why Rules for Chart Work? • Good habits will reduce errors • Mistakes are easier to find • Information is clear for future use • Other boaters can follow your work • To know you are in Safe Water

  6. Accuracy Standards Angular Measurement - Nearest Whole Degree - 214 º (with three digits) Distance - Nearest one-tenth of a mile - 6.5 nm Speed - Nearest one-tenth of a knot - 4.3 kn Time - Nearest whole minute - 43 m

  9. DRAW THE COURSE LINE USING THE QUIK COURSE PLOTTER AS A STRAIGHT EDGE

  10. Place Center at Beginning of Course

  11. Determine the Course Read: 067 1 Plot the course 2 Check it for safe passage 3 Measure the course direction (true)

  12. C 067 Labeling A Course Line Course 067° true Place the true course direction near the beginning of the course

  13. C067

  14. Class Exercise #4 On the Bowditch Bay practice chart, determine and label the reciprocal course in Exercise #3. Update Variation to the current year. Determine magnetic and compass courses.

  15. C 247 Course 247° True Labeling A Course Line reciprocal 067 180 247 Place the true course direction near the beginning of the course

  16. C247

  17. The TVMDC Formula True Course T _247°_ Variation V _15°W_ Add Add East West Magnetic Course M _262°_ Subtract Subtract East West Deviation D _0°_ Compass Course C _262°_ Deviation is assumed to be 0 for demonstration only °
