At 0745 you take two bearings with a hand-bearing compass: Mill stack bears 192°M and Westfield church spire 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 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
At 1550 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 134°M and Westfield church spire bears 235°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
At 0925 you take two bearings with a hand-bearing compass: Heron Point Light bears 244°M and Westfield church spire bears 306°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
At 1745 you take two bearings with a hand-bearing compass: Westfield church spire bears 276°M and Heron Point Light bears 222°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
At 1030 you take two bearings with a hand-bearing compass: Westfield church spire bears 295°M and Mill stack bears 203°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
