  1. At 1515 you take two bearings with a hand-bearing compass: Heron Point Light bears 212°M and Gannet Rock daybeacon bears 125°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  

  2. At 0705 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 110°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  

  3. At 1600 you take two bearings with a hand-bearing compass: Westfield church spire bears 227°M and Gannet Rock daybeacon bears 131°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 1640 you take two bearings with a hand-bearing compass: Heron Point Light bears 274°M and Kittle water tank bears 159°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 1610 you take two bearings with a hand-bearing compass: Heron Point Light bears 193°M and Westfield church spire bears 311°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 0820 you take two bearings with a hand-bearing compass: Heron Point Light bears 220°M and Gannet Rock daybeacon bears 131°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 0920 you take two bearings with a hand-bearing compass: Westfield church spire bears 271°M and Heron Point Light bears 192°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 1200 you take two bearings with a hand-bearing compass: Heron Point Light bears 256°M and Mill stack bears 202°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
