At 0940 you take two bearings with a hand-bearing compass: Mill stack bears 187°M and Heron Point Light bears 239°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 1210 you take two bearings with a hand-bearing compass: Gannet Rock daybeacon bears 303°M and Kittle water tank 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 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 0725 you take two bearings with a hand-bearing compass: Mill stack bears 195°M and Gannet Rock daybeacon bears 106°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 1730 you take two bearings with a hand-bearing compass: Kittle water tank bears 183°M and Gannet Rock daybeacon bears 267°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

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 0755 you take two bearings with a hand-bearing compass: Westfield church spire bears 283°M and Mill stack bears 194°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

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 252°M and Kittle water tank bears 160°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.
