General Deviation = 0° Variation = 20°E All positions and lines plotted on the chart should adhere to labeling conventions in Supplementary Material Use Piloting Training Chart C Plot DRs every whole hour whenever a change of speed or course Whenever a bearing is taken or fix is obtained No wind or current Show all work and calculations

  3. Depart Refuge Cove @ 09:00

  4. 7-3.1 Plot and label your 0937 Fix. 0937 0.5 nm

  5. @ 09:37 you are ½ mile due West of Fl R Light, entrance to Refuge Cove.

  6. Question 7-3.2 What are the coordinates of your 0937 fix? 0937 L 50º 06.9’ N Lo 124º 51.8’ W

  7. You proceed on a course of 126°(T) at a speed of 5.0 knots 7-3.3 Plot and label your course line Plotter used to chart a course line of 126° 0937 106° Magnetic obtained from Plotter or Calculation C 126 / 106 M S 5.0

  8. Question 7-3.4 What Compass Course Will You Steer ? T V M D C 126 20 E 106 0 106

  9. After running this course for 30 minutes, you take two compass bearing on two fixed aids as follows: • The light on West Redonda Island - ‘Fl 10s 20m 15M’ bears 335°(C) • The light on Mink Island - ‘Fl(2) 12s 18m 12M’ bears 044°(C)

  10. Question 7-3.5 What is the true bearing of the light on West Redonda Island? T V M D C 355 20 E 335 0 335

  11. Question 7-3.6 What is the true bearing of the light on Mink Island? T V M D C 064 20 E 044 0 044

  12. 7-3.7 Plot and label this fix. Plotter used to chart a bearing of 355° Plotter used to chart a bearing of 064° C 126 / 106 M 335° Magnetic obtained from Plotter or Calculation 355 S 5.0 / 335 M / 044 M 064 1007 044° Magnetic obtained from Plotter or Calculation

  13. Question 7-3.8 What are the coordinates of this fix? C 126 / 106 M 355 S 5.0 / 335 M / 044 M 064 1007 L 50º 05.6’ N Lo 124º 48.5’ W

  14. Mink Island Looking North East up right arm of Desolation Sound

  15. 7-3.9 Alter course to 092°(T) – Increase speed to 6.0 knots Plot and label your course line. C 126 / 106 M 355 S 5.0 072° Magnetic obtained from Plotter or Calculation / 335 M / 044 M 064 1007 C 092 / 072 M S 6.0 Plotter used to chart a course line of 092°

  16. Question 7-3.10 What will be the true bearing of the Mink Island Light when it is abeam to Port? 092 (course) - 090 (abeam) = 002 to Port

  17. Mink Island light will have a bearing of 002(T) when you are abeam to Port C 126 / 106 M 355 S 5.0 / 335 M / 044 M / 342 M 064 002 1007 C 092 / 072 M S 6.0

  18. Question 7-3.11 When will Mink Island light will be abeam to Port C 126 / 106 M 355 S 5.0 / 335 M / 044 M / 342 M 064 002 1007 C 092 / 072 M S 6.0 0.9 nm

  19. Question 7-3.11 When will the Mink Island light be abeam to Port? t = 60 X 0.9 6 t = 60 X D S ETA 1007 + 9 = 1016 t = 9.0 minutes

  20. Question 7-3.12 Plot the DR position for the time when the Mink Island light will be abeam to Port C 126 / 106 M 355 S 5.0 / 335 M / 044 M / 342 M 064 002 1016 1007 C 092 / 072 M S 6.0

  23. At 1155, you hear a distress call on your marine radio. A boater has struck Pringle Rock just west of Morgan Island and requests assistance. 1155 Distress Call

  24. You are near the north western end of the most northern of the Curme Islands

  25. You answer the call and inform him you are northwest of the most northern of the Curme Islands [use the point of the (34) as your location] and are on your way at a speed of 20.0 knots. 1155

  26. Question 7-3.13 Plot and label your course line. 009° Magnetic obtained from Plotter or Calculation Plotter used to determine the direction of the course line is 029° / 009 M C 029 S 20.0 1155

  27. Question 7-3.14 What is your estimated time of arrival (ETA) at Pringle Rock? 1.3 nm / 009 M C 029 S 20.0 1155

  28. Question 7-3.14. What is your estimated time of arrival (ETA) at Pringle Rock? t = 60 X 1.3 20 t = 60 X D S t = 3.9 (round to 4) minutes ETA 1155 + 4 = 1159

  29. When you reach Pringle Rock, you find a 5-metre runabout floating and not taking on water, but with a severely damaged outboard drive unit and propeller. The operator, though unhurt, is very upset with himself for not exercising more care in his navigation. You fashion a towing bridle and begin the tow back to his cabin at Roscoe Bay. / 004 M C 024 S 20.0 1155

  30. At 1225, you leave Pringle Rock on a course for Marylebone Point at a speed of 4.0 knots. 1225 / 004 M C 024 S 20.0 1155

  31. Question 7-3.15. What is your true course? Plotter used to determine the direction of the course line is 330° C 330 1225 / 004 M C 024 S 20.0 1155

  32. T V M D C Question 7-3.16. What is your compass course? 330 20 E 310 0 310

  33. Question 7-3.16 What is your compass course? C 330 S 4.0 / 310 M T V M D C 1225 330 20 E 310 0 310 310° Magnetic obtained from Plotter or Calculation / 004 M C 024 S 20.0 1155

  34. Question 7-3.17 At what time will you be close aboard Marylebone Point ? 1.6 nm C 330 S 4.0 / 310 M 1225 1225 / 004 M C 024 S 20.0 1155

  35. t = 60 X 1.6 4 Question 7-3.17 At what time will you be close aboard Marylebone Point ? t = 60 X D S t = 24 minutes ETA 1225 + 24 = 1249

  36. Question 7-3.18 What are the coordinates of Marylebone Point Light? L 50° 09.7’ N Lo 124° 45.1’ W

  37. You round Marylebone Point and enter Rosecoe Bay
