  1. At 0845 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 129°M and Heron Point Light bears 214°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 1445 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 106°M and Heron Point Light bears 205°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 0810 you take two bearings with a hand-bearing compass: Mill stack bears 178°M and Heron Point Light bears 232°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 1445 you take two bearings with a hand-bearing compass: Mill stack bears 220°M and Kittle water tank 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 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 0950 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 111°M and Heron Point Light bears 186°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  

  6. At 0710 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  

  7. At 1535 you take two bearings with a hand-bearing compass: Mill stack bears 224°M and Kittle water tank bears 163°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  

  8. At 1610 you take two bearings with a hand-bearing compass: Kittle water tank bears 187°M and Gannet Rock daybeacon bears 247°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
