Question 1 - Steps & Calculations:

1. Find your 0900 position.

2. From this fix, draw your 210° T course line and label properly.

3. Find Woods Hole water tower.

4. Convert the Magnetic bearing to the water tower to True direction.
   265 M - 10 W = 255 T

5. Plot this true LOP from the water tower to your present location.

6. Convert the Magnetic direction of the second bearing of 000° on the water tower to True direction.
   000 M - 10 W = 350 T

7. Plot the second bearing of 350 T from the water tower.

8. Find your 0945 DR position. First calculate how long you traveled (45 minutes), then convert to a decimal (45 ÷ 60 = .75 hours)

9. Next find how far you have traveled in .75 hours by using the DST formula.
   S × T = D - 4kts × .75 = 3 nm

10. Plot your 0945 DR position 3 nm along your course line.

11. Place your parallel rules along the 0900 bearing to the water tower. Now, walk the parallel rules until they intersect with your DR position at 0945. Draw a line along the edge of the parallel rules that cross your DR position. Where this advanced LOP crosses the 0945 LOP is your running fix at 0945.

12. Find the latitude and longitude of this location.

Question 2 - Steps & Calculations:

1. From this 0945 running fix, draw your 270° T course line and label properly.

2. Convert the new Magnetic bearing to the water tower to True direction.
   050 M - 10 W = 040 T

3. Plot this true LOP from the water tower.

4. Find your 1015 DR position. First calculate how long you traveled (30 minutes), then convert to a decimal (30 ÷ 60 = .50 hours)

5. Next find how far you have traveled in .50 hours by using the DST formula.
   S × T = D - 4kts × .50 = 2 nm

6. Plot your 1015 DR position 2 nm along your course line.

7. Place your parallel rules along the 0945 bearing to the water tower. Now, walk the parallel rules until they intersect with your DR position at 1015. Draw a line along the edge of the parallel rules that cross your DR position. Where this advanced LOP crosses the 1015 LOP on the water tower is your running fix at 1015. Remember when using the same object to advance bearings to get a running fix, always advance the latest bearing. In this case the 0945 not the 0900.

8. Find the latitude and longitude of this location.

Question 3 - Steps & Calculations:

Mini-Chart #2-A - Variation 14W

1. Find your 1000 position.

2. From this fix, draw your 090° T course line and label properly.

3. Convert the Magnetic bearing to the Brenton Reef Light to True direction.
   074 M - 14 W = 060 T

4. Plot this true LOP from the Brenton Reef Light to your present location.

5. Convert the Magnetic direction of the second bearing of 304° on Brenton Reef Light to True direction.
   304 M - 14 W = 290 T

6. Plot the second bearing of 290 T from the Brenton Reef Light.

7. Find your 1030 DR position. First calculate how long you traveled (30 minutes), then convert to a decimal (30 ÷ 60 = .50 hours)

8. Next find how far you have traveled in .50 hours by using the DST formula.
   S × T = D - 4kts × .50 = 2 nm

9. Plot your 1030 DR position 2 nm along your course line.

10. Place your parallel rules along the 1000 bearing to Brenton Reef Light. Now, walk the parallel rules until they intersect with your DR position at 1030. Draw a line along the edge of the parallel rules that cross your DR position. Where this advanced LOP crosses the 1030 LOP on the Brenton Reef Light is your running fix at 1030.

11. Find the latitude and longitude of this location.

Question 4 - Steps & Calculations:

1. From this 1030 running fix, draw your 350° T course line and label properly. (Remember you have increased your speed to 6 kts.)

2. Convert the new Magnetic bearing to the Brenton Reef Light to True direction.
   214 M - 14 W = 200 T

3. Plot this true LOP from the Brenton Reef Light.

4. Find your 1100 DR position. First calculate how long you traveled (30 minutes), then convert to a decimal (30 ÷ 60 = .50 hours)

5. Next find how far you have traveled in .50 hours by using the DST formula.
   S × T = D - 6kts × .50 = 3 nm

6. Plot your 1100 DR 3 nm along your course line.

7. Place your parallel rules along the 1030 bearing to the Brenton Reef Light. Now, walk the parallel rules until they intersect with your DR position at 1100. Draw a line along the edge of the parallel rules that cross your DR position. Where this advanced LOP crosses the 1100 LOP on the Brenton Reef Light is your running fix at 1100.

8. Find the latitude and longitude of this location.
