At 0925 you take two bearings with a hand-bearing compass: Heron Point Light bears 247°M and Gannet Rock daybeacon bears 117°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 1240 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 312°M and Kittle water tank bears 188°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 1205 you take two bearings with a hand-bearing compass: Heron Point Light bears 198°M and Gannet Rock daybeacon bears 129°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
At 1230 you take two bearings with a hand-bearing compass: Mill stack bears 196°M and Kittle water tank bears 142°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 1150 you take two bearings with a hand-bearing compass: Heron Point Light bears 270°M and Kittle water tank bears 149°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
At 0910 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 100°M and Heron Point Light bears 195°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
At 0810 you take two bearings with a hand-bearing compass: Heron Point Light bears 272°M and Mill stack bears 219°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
At 0750 you take two bearings with a hand-bearing compass: Westfield church spire bears 294°M and Mill stack bears 183°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).
