1. At 1335 you take two bearings with a hand-bearing compass: Mill stack bears 177°M and Westfield church spire bears 252°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 1015 you take two bearings with a hand-bearing compass: Westfield church spire bears 281°M and Mill stack bears 210°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 Tern Island tower to the fix, and the distance.

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

   Bearing from Tern Island tower: ________ °T   Distance: ________ nm  

3. At 1345 you take two bearings with a hand-bearing compass: Kittle water tank bears 204°M and Gannet Rock daybeacon bears 305°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 Bell buoy "HS" to the fix, and the distance.

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

   Bearing from Bell buoy "HS": ________ °T   Distance: ________ nm  

4. At 0835 you take two bearings with a hand-bearing compass: Heron Point Light bears 205°M and Westfield church spire bears 288°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 0740 you take two bearings with a hand-bearing compass: Mill stack bears 152°M and Heron Point Light bears 277°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  

6. At 0905 you take two bearings with a hand-bearing compass: Heron Point Light bears 244°M and Westfield church spire bears 300°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  

7. At 1555 you take two bearings with a hand-bearing compass: Heron Point Light bears 259°M and Mill stack bears 165°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  

8. At 0920 you take two bearings with a hand-bearing compass: Mill stack bears 203°M and Westfield church spire bears 292°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
