At 0950 you take two bearings with a hand-bearing compass: Kittle water tank bears 145°M and Mill stack bears 211°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 1515 you take two bearings with a hand-bearing compass: Westfield church spire bears 317°M and Gannet Rock daybeacon bears 077°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 1520 you take two bearings with a hand-bearing compass: Heron Point Light bears 255°M and Mill stack bears 154°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 1640 you take two bearings with a hand-bearing compass: Westfield church spire bears 293°M and Mill stack 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 "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 1730 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 282°M and Kittle water tank bears 212°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
At 1625 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 099°M and Heron Point Light bears 184°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 0730 you take two bearings with a hand-bearing compass: Mill stack bears 194°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 1155 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 122°M and Heron Point Light bears 246°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
