At 1130 you take two bearings with a hand-bearing compass: Westfield church spire bears 240°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 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 1135 you take two bearings with a hand-bearing compass: Heron Point Light bears 216°M and Westfield church spire bears 313°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 1630 you take two bearings with a hand-bearing compass: Heron Point Light bears 186°M and Westfield church spire bears 310°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 1355 you take two bearings with a hand-bearing compass: Mill stack bears 153°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 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 1545 you take two bearings with a hand-bearing compass: Heron Point Light bears 185°M and Gannet Rock daybeacon bears 108°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 1125 you take two bearings with a hand-bearing compass: Heron Point Light bears 265°M and Mill stack 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 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 1035 you take two bearings with a hand-bearing compass: Heron Point Light bears 237°M and Mill stack bears 182°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 0705 you take two bearings with a hand-bearing compass: Mill stack bears 219°M and Westfield church spire bears 294°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
