At 1540 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 096°M and Heron Point Light bears 168°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 1020 you take two bearings with a hand-bearing compass: Mill stack bears 198°M and Westfield church spire bears 277°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 1055 you take two bearings with a hand-bearing compass: Westfield church spire bears 277°M and Mill stack bears 168°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 1320 you take two bearings with a hand-bearing compass: Heron Point Light bears 212°M and Westfield church spire bears 279°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 1350 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 311°M and Kittle water tank bears 213°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 1215 you take two bearings with a hand-bearing compass: Mill stack bears 175°M and Westfield church spire bears 242°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 1550 you take two bearings with a hand-bearing compass: Mill stack bears 179°M and Gannet Rock daybeacon bears 071°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 1350 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 294°M and Kittle water tank 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 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
