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

Depart Refuge Cove @ 09:00

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

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

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

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

TVMDC Question 7-3.4 What Compass Course Will You Steer ? 12620 E1060

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)

TVMDC Question 7-3.5 What is the true bearing of the light on West Redonda Island? 35520 E3350

TVMDC Question 7-3.6 What is the true bearing of the light on Mink Island? 06420 E0440

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

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

Looking North East up right arm of Desolation Sound Mink Island

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

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

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

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

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

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

Exploring East coast Mink Island

Crume Islands Mink Island Still exploring

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

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

You answer the call and inform him you are northwest of the most northern of the Curme Islands [use the point of the (3 4 ) as your location] and are on your way at a speed of 20.0 knots. 1155

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

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

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

C 024 / 004 M S 20.0 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. 1155

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

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

TVMDC 33020 E3100 Question 7-3.16.What is your compass course?

C 024 / 004 M S 20.0 1155 1225 C 330 / 310 M TVMDC 33020 E3100 310° Magnetic obtained from Plotter or Calculation S 4.0 Question 7-3.16What is your compass course?

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

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

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

You round Marylebone Point and enter Rosecoe Bay
