1. At 1210 you take two bearings with a hand-bearing compass: Mill stack bears 158°M and Westfield church spire 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 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 0835 you take two bearings with a hand-bearing compass: Westfield church spire bears 274°M and Mill stack bears 168°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  

3. At 0840 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 119°M and Mill stack bears 209°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 1645 you take two bearings with a hand-bearing compass: Westfield church spire bears 239°M and Mill stack 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 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 1235 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 103°M and Mill stack bears 154°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 0810 you take two bearings with a hand-bearing compass: Heron Point Light bears 260°M and Mill stack bears 208°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 1635 you take two bearings with a hand-bearing compass: Westfield church spire bears 278°M and Mill stack bears 177°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 1515 you take two bearings with a hand-bearing compass: Heron Point Light bears 270°M and Mill stack bears 153°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
