Transit
An alignment of two fixed objects seen from the vessel.
This can be used as a simple and reliable visual reference for position, clearing dangers or checking whether a vessel is on a planned line. When the two objects appear directly in line, the vessel lies somewhere along that line of position. Useful pairs might include beacons, posts, church towers, leading marks or prominent shore features. Transits are especially helpful in pilotage because they give immediate visual confirmation without needing bearings or electronic equipment.
