  1. At 0715 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 121°M and Mill stack bears 175°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 1235 you take two bearings with a hand-bearing compass: Mill stack bears 152°M and Westfield church spire bears 280°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  

  3. At 0745 you take two bearings with a hand-bearing compass: Mill stack bears 180°M and Westfield church spire bears 290°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 1140 you take two bearings with a hand-bearing compass: Heron Point Light bears 240°M and Westfield church spire bears 323°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  

  5. At 1750 you take two bearings with a hand-bearing compass: Westfield church spire bears 320°M and Gannet Rock daybeacon bears 085°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 1010 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 070°M and Westfield church spire bears 303°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 Mill stack to the fix, and the distance.

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

    Bearing from Mill stack: ________ °T   Distance: ________ nm  

  7. At 1110 you take two bearings with a hand-bearing compass: Westfield church spire bears 246°M and Heron Point Light bears 194°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 1305 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 089°M and Mill stack bears 156°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
