1. At 1510 you take two bearings with a hand-bearing compass: Heron Point Light bears 253°M and Mill stack bears 171°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  

2. At 1145 you take two bearings with a hand-bearing compass: Heron Point Light bears 222°M and Westfield church spire bears 273°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  

3. At 1545 you take two bearings with a hand-bearing compass: Mill stack bears 193°M and Westfield church spire bears 294°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  

4. At 0700 you take two bearings with a hand-bearing compass: Westfield church spire bears 300°M and Mill stack bears 188°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  

5. At 0945 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 099°M and Heron Point Light bears 184°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 0900 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 348°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 Kittle water tank to the fix, and the distance.

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

   Bearing from Kittle water tank: ________ °T   Distance: ________ nm  

7. At 1410 you take two bearings with a hand-bearing compass: Westfield church spire bears 256°M and Mill stack bears 192°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  

8. At 1620 you take two bearings with a hand-bearing compass: Westfield church spire bears 298°M and Mill stack bears 211°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
