SQUARED AWAY

Yards held rigidly perpendicular to their masts and parallel to the deck. This was rarely the best trim of the yards for efficiency but made a pretty sight for inspections and in harbor.

AGETON

A divided triangle method of sight reduction in which a perpendicular is dropped from the GP of the body to the meridian of the observer

BOUNDARY LINES OF INLAND WATERS

Lines dividing the high seas from rivers, harbors, and inland waters. The waters inshore of the lines are 'inland waters' and upon them the Inland Rules of the Road or Pilot Rules apply. The waters outside of the lines are the high seas and upon them the International Rules apply.

CELESTIAL OBSERVATION

Observation of celestial phenomena. The expression is applied in navigation principally to the measurement of the altitude of a celestial body, and sometimes to measurement of azimuth, or to both altitude azimuth. The expression may also be applied to the data obtained by such measurement. Also called SIGHT in navigation usage.

COLLIMATE

1. To render parallel, as rays of light. 2. To adjust the line of sight of an optical instrument, such as a theodolite, in proper relation to other parts of the instrument

COASTING

Proceeding approximately parallel to a coastline (headland to headland) in sight of land, o

MAKE THE LAND

To sight and approach or reach land from seaward.

COLLIMATION ERROR

The angle by which the line of sight of an optical instrument differs from its collimation axis. Also called ERROR OF COLLIMATION

DIP

1. The vertical angle, at the eye of an observer, between the horizontal and the line of sight to the visible horizon. Altitudes of celestial bodies measured from the visible sea horizon as a reference are too great by the amount of dip. Since dip arises from and varies with the elevation of the eye of the observer above the surface of the earth, the correction for dip is sometimes called HEIGHT OF EYE CORRECTION. Dip is smaller than GEOMETRICAL DIP by the amount of terrestrial refraction. Also called DIP OF THE HORIZON. 2. The angl

DOUBLE STAR

Two stars appearing close together. If they appear close because they are in nearly the same line of sight but differ greatly in distance from the observer, they are called an optical double star; if in nearly the same line of sight and at approximately the same distance from the observer, they are called a physical double star. If they revolve about their common center of mass, they are called a binary star.
