  1. At 1210 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 110°M and Heron Point Light bears 230°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 1345 you take two bearings with a hand-bearing compass: Kittle water tank bears 167°M and Mill stack 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 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  

  3. At 1645 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 130°M and Heron Point Light bears 201°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 1050 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 089°M and Mill stack bears 152°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 1330 you take two bearings with a hand-bearing compass: Mill stack bears 182°M and Westfield church spire bears 255°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 1755 you take two bearings with a hand-bearing compass: Heron Point Light bears 242°M and Westfield church spire bears 304°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 1615 you take two bearings with a hand-bearing compass: Mill stack bears 155°M and Gannet Rock daybeacon bears 101°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 0900 you take two bearings with a hand-bearing compass: Westfield church spire bears 286°M and Mill stack bears 164°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
