Bowditch Ch. 7 §707
Bowditch Ch. 7 §707 — Bearings and Lines of Position Visual piloting fixes the vessel by bearings and ranges to charted landmarks and aids to navigation. The strongest fixes cross their LOPs near 90 degrees, use objects positively identified on the chart, and are observed in quick succession with the beam-most object taken last. Danger bearings and clearing lines supplement the fix to keep the vessel off charted hazards between fixes.
