1. At 1030 you take two bearings with a hand-bearing compass: Heron Point Light bears 256°M and Kittle water tank bears 159°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  

2. At 1105 you take two bearings with a hand-bearing compass: Mill stack bears 167°M and Westfield church spire bears 291°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  

3. At 1630 you take two bearings with a hand-bearing compass: Heron Point Light bears 185°M and Gannet Rock daybeacon bears 113°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  

4. At 1405 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 131°M and Westfield church spire bears 247°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  

5. At 0705 you take two bearings with a hand-bearing compass: Mill stack bears 173°M and Westfield church spire bears 262°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  

6. At 1445 you take two bearings with a hand-bearing compass: Mill stack bears 215°M and Kittle water tank bears 152°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  

7. At 0955 you take two bearings with a hand-bearing compass: Heron Point Light bears 249°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 "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  

8. At 0710 you take two bearings with a hand-bearing compass: Mill stack bears 215°M and Kittle water tank bears 161°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
