1. At 1505 you take two bearings with a hand-bearing compass: Mill stack bears 213°M and Heron Point Light bears 269°M.

   Variation is 7°W (from the rose); a hand-bearing compass held away from the boat's steel is taken to have no deviation. Convert to true, plot the two lines of position, and give the fix as the true bearing FROM Green can "3" to the fix, and the distance.

   Tolerance: 2° and 0.15 nm (or 4 % of the distance).

   Bearing from Green can "3": ________ °T   Distance: ________ nm  

2. At 1610 you take two bearings with a hand-bearing compass: Heron Point Light bears 251°M and Kittle water tank bears 157°M.

   Variation is 7°W (from the rose); a hand-bearing compass held away from the boat's steel is taken to have no deviation. Convert to true, plot the two lines of position, and give the fix as the true bearing FROM Gannet Rock daybeacon to the fix, and the distance.

   Tolerance: 2° and 0.15 nm (or 4 % of the distance).

   Bearing from Gannet Rock daybeacon: ________ °T   Distance: ________ nm  

3. At 1410 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 113°M and Heron Point Light bears 204°M.

   Variation is 7°W (from the rose); a hand-bearing compass held away from the boat's steel is taken to have no deviation. Convert to true, plot the two lines of position, and give the fix as the true bearing FROM Red nun "2" to the fix, and the distance.

   Tolerance: 2° and 0.15 nm (or 4 % of the distance).

   Bearing from Red nun "2": ________ °T   Distance: ________ nm  

4. At 1045 you take two bearings with a hand-bearing compass: Westfield church spire bears 243°M and Heron Point Light bears 180°M.

   Variation is 7°W (from the rose); a hand-bearing compass held away from the boat's steel is taken to have no deviation. Convert to true, plot the two lines of position, and give the fix as the true bearing FROM Green can "1" to the fix, and the distance.

   Tolerance: 2° and 0.15 nm (or 4 % of the distance).

   Bearing from Green can "1": ________ °T   Distance: ________ nm  

5. At 1635 you take two bearings with a hand-bearing compass: Heron Point Light bears 203°M and Westfield church spire bears 259°M.

   Variation is 7°W (from the rose); a hand-bearing compass held away from the boat's steel is taken to have no deviation. Convert to true, plot the two lines of position, and give the fix as the true bearing FROM Red nun "2" to the fix, and the distance.

   Tolerance: 2° and 0.15 nm (or 4 % of the distance).

   Bearing from Red nun "2": ________ °T   Distance: ________ nm  

6. At 1600 you take two bearings with a hand-bearing compass: Heron Point Light bears 197°M and Gannet Rock daybeacon bears 128°M.

   Variation is 7°W (from the rose); a hand-bearing compass held away from the boat's steel is taken to have no deviation. Convert to true, plot the two lines of position, and give the fix as the true bearing FROM Westfield church spire to the fix, and the distance.

   Tolerance: 2° and 0.15 nm (or 4 % of the distance).

   Bearing from Westfield church spire: ________ °T   Distance: ________ nm  

7. At 1605 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 113°M and Heron Point Light bears 197°M.

   Variation is 7°W (from the rose); a hand-bearing compass held away from the boat's steel is taken to have no deviation. Convert to true, plot the two lines of position, and give the fix as the true bearing FROM Red nun "2" to the fix, and the distance.

   Tolerance: 2° and 0.15 nm (or 4 % of the distance).

   Bearing from Red nun "2": ________ °T   Distance: ________ nm  

8. At 1350 you take two bearings with a hand-bearing compass: Kittle water tank bears 144°M and Gannet Rock daybeacon bears 061°M.

   Variation is 7°W (from the rose); a hand-bearing compass held away from the boat's steel is taken to have no deviation. Convert to true, plot the two lines of position, and give the fix as the true bearing FROM Green can "3" to the fix, and the distance.

   Tolerance: 2° and 0.15 nm (or 4 % of the distance).

   Bearing from Green can "3": ________ °T   Distance: ________ nm
