At 1445 you take two bearings with a hand-bearing compass: Mill stack bears 191°M and Westfield church spire bears 293°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 1600 you take two bearings with a hand-bearing compass: Kittle water tank bears 147°M and Heron Point Light bears 250°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 1450 you take two bearings with a hand-bearing compass: Mill stack bears 216°M and Kittle water tank bears 163°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 1615 you take two bearings with a hand-bearing compass: Mill stack bears 196°M and Gannet Rock daybeacon bears 072°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 0710 you take two bearings with a hand-bearing compass: Kittle water tank bears 144°M and Heron Point Light bears 245°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 1515 you take two bearings with a hand-bearing compass: Mill stack bears 207°M and Westfield church spire bears 278°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 1020 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 073°M and Mill stack bears 152°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 0935 you take two bearings with a hand-bearing compass: Kittle water tank bears 222°M and Gannet Rock daybeacon bears 318°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
