Precision Anchoring, Continued
Step
Action
2.
Lay out and label the approach track (minimum of 1,000 yd) and label as
shown in figure 12-9.
3.
Lay out and label the intended track that will intercept the approach track.
4.
Lay out and label the turn bearing for the turn onto the approach track. In
figure 12-9, a turn bearing of 345° on the tank is used.
5.
Lay out the letting-go circle; remember that the radius of this circle is equal to
the distance from the pelorous to the hawsepipe.
6.
Lay out and label the letting-go bearing (LGB). In figure 12-9, a LGB of 096°
is constructed using the stack.
7.
Lay out range to anchorage distance arcs beginning at the edge of the letting-go
circle. Use 100-yard increments out to 1,000 yards and then also at 1,200,
1,500, and 2,000 yards, as shown in figure 12-9.
