1. At 1410 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 155°M and Heron Point Light bears 250°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 0725 you take two bearings with a hand-bearing compass: Kittle water tank bears 162°M and Heron Point Light bears 248°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 0810 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 092°M and Mill stack bears 145°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  

4. At 1320 you take two bearings with a hand-bearing compass: Westfield church spire bears 311°M and Heron Point Light bears 235°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 1345 you take two bearings with a hand-bearing compass: Mill stack bears 187°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 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 1540 you take two bearings with a hand-bearing compass: Westfield church spire bears 296°M and Heron Point Light bears 240°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  

7. At 0855 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 132°M and Westfield church spire bears 242°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 1725 you take two bearings with a hand-bearing compass: Westfield church spire bears 262°M and Heron Point Light bears 207°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
