  1. At 0945 you take two bearings with a hand-bearing compass: Kittle water tank bears 189°M and Gannet Rock daybeacon 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 Bell buoy "HS" to the fix, and the distance.

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

    Bearing from Bell buoy "HS": ________ °T   Distance: ________ nm  

  2. At 1225 you take two bearings with a hand-bearing compass: Mill stack bears 210°M and Heron Point Light bears 261°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 1145 you take two bearings with a hand-bearing compass: Heron Point Light bears 179°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 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 1250 you take two bearings with a hand-bearing compass: Kittle water tank bears 150°M and Heron Point Light 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 Gannet Rock daybeacon to the fix, and the distance.

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

    Bearing from Gannet Rock daybeacon: ________ °T   Distance: ________ nm  

  5. At 0725 you take two bearings with a hand-bearing compass: Mill stack bears 200°M and Westfield church spire bears 300°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  

  6. At 1025 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 315°M and Kittle water tank bears 200°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 Bell buoy "HS" to the fix, and the distance.

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

    Bearing from Bell buoy "HS": ________ °T   Distance: ________ nm  

  7. At 1205 you take two bearings with a hand-bearing compass: Heron Point Light bears 227°M and Mill stack bears 166°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  

  8. At 1035 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 131°M and Heron Point Light bears 220°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
