1. At 1355 you take two bearings with a hand-bearing compass: Westfield church spire bears 311°M and Gannet Rock daybeacon bears 069°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 Mill stack to the fix, and the distance.

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

   Bearing from Mill stack: ________ °T   Distance: ________ nm  

2. At 1430 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 111°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 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  

3. At 1620 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 114°M and Heron Point Light bears 183°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 1025 you take two bearings with a hand-bearing compass: Westfield church spire bears 269°M and Mill stack bears 181°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 1300 you take two bearings with a hand-bearing compass: Mill stack bears 192°M and Westfield church spire bears 256°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  

6. At 0835 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 077°M and Westfield church spire bears 309°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 1310 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 081°M and Mill stack bears 179°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 1635 you take two bearings with a hand-bearing compass: Mill stack bears 172°M and Heron Point Light 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 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
