TRIM – the difference between aft and forward draft.
STABILITY – ability of the ship to return to its original position after the disturbance of outside force.
DRAFT – the submerged body of the ship measured from the keel to the water line.
METEOROLOGY – study of science that deals with the study of phenomena. Things that happen and observed in the atmosphere.

SEAMANSHIP – the efficient work of a seaman on-board.
ELECTRONIC NAVIGATION – kind of navigation that uses electronic devices such as RADAR, Radio Direction Finder to navigate the ship.
BALLASTING – a process of putting water in the ballast tank so that the ship will be upright.
BUOYANCY – is the upward vertical support by the water in which the vessel is floating.
DEAD RECKONING – the process of calculating one’s current position by using a previously determined position, and advancing that position based upon known or estimated speeds over elapsed time, and course.
WINDLASS – is used to raise and lower the anchor.
WINCH – is used to pull in, let out, or adjust tension of a rope.
CAPSTAN – is used to secure mooring lines.
ANCHOR – is used to prevent the ship from drifting.
SOLID MENSURATION – process of knowing the dimension, volume, or area of any figure.
SALT/FRESH WATER – when entering salt water area, the draft of your ship decreases. While when entering fresh water area, the draft of your ship increases.
FOG – is a cloud whose base is low enough to restrict visibility. It is composed of droplets of water or ice crystals formed by crystallization of water vapor in the air.
CLOUDS – numerous tiny droplets of water or ice crystals formed by condensation of water vapor in air.
CLIMATE – refers to the prevalent or meteorological characteristic of a region.
MARITIME LAW – is a part of commercial laws, which strictly relates to shipping and its incidents. It is the law of the sea and governs acts arising out of maritime commerce.
EARTH – approximately an oblate spheroid. However, for many navigational purposes, the Earth is assumed to be sphere without intolerable end.
DISTANCE – is the spatial separation of two points and is expressed as the length joining them.
COURSE – the direction in which a vessel is steered or intended to be steered.
BACK – intended or desired horizontal direction of travel with respect to the Earth and also the path of intended travel.
FIX – is the common intersection of two or more lines of position obtained from simultaneous observations.
PILOTING – is navigation involving frequent or continuous determination of position or LOP relative to geographic points.
SAILING – is a various method of solving various problems involving course, distance, DLAT, DLO, ETD, ETA, and the duration of steaming time.
SEXTANT – is a handheld instrument for measuring the angle between the line of sight of two points by bringing into coincide at the eye of the observer. A double reflecting instrument for measuring angles primarily altitudes of the celestial bodies.
LIST – is a transverse angle of inclination of a vessel caused by external forces acting on the ship that affects the vessel’s stability.
DISPLACEMENT – is the weight of the vessel equal to the weight of the water being displaced.
MATHEMATICS – is the study of numbers, it involves addition, subtraction, multiplication, and division.
ALGEBRA – is the branch of Mathematics that deals with the algebraic expressions and variables and represented by a letter.
TRIGONOMETRY – is the branch of Mathematics which deals with the study of triangles and the relationship between their sides and the angles between these sides.

DYNAMICS – the study of the causes of motion and changes in motion.
KINEMATICS – is the branch of classical mechanics that describes the motion of points, bodies (objects) and systems of bodies (groups of objects) without consideration of the causes of motion.
POTENTIAL ENERGY – energy not in use.
KINETIC ENERGY – energy in motion.
ENTROPY – is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work.
ENERGY – is the ability to do work.
ENGINEERING – is an applied science which deals with construction and maintenance.
COMMUNICATION – is an act of passing or transmitting ideas or information between sender and the receiver.
