  1. At 1155 you take two bearings with a hand-bearing compass: Heron Point Light bears 232°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 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 0840 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 036°M and Heron Point Light bears 275°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  

  3. At 1605 you take two bearings with a hand-bearing compass: Heron Point Light bears 228°M and Gannet Rock daybeacon bears 112°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 0955 you take two bearings with a hand-bearing compass: Westfield church spire bears 255°M and Mill stack bears 172°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 1740 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 093°M and Heron Point Light bears 174°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 1710 you take two bearings with a hand-bearing compass: Heron Point Light bears 239°M and Mill stack bears 182°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  

  7. At 0825 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 107°M and Mill stack bears 174°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 1035 you take two bearings with a hand-bearing compass: Heron Point Light bears 192°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
