 **************************

Greenwich Mean Time(GMT)-- same as Universal Coordinated Time(UCT),
						   or ZULU Time.

True Course(TC)-- The direction to travel, from a point of departure
                  to a destination/waypoint, plotted on a chart in
                  relation to true north (of course meridians of
                  longitude run north).

Magnetic Course(MC)-- The true course corrected for variation.

Compass Course(CC)-- The magnetic course corrected for deviation.

Compass Course Made Good(CCmg)-- The compass heading with
               corrections for variation, deviation and current
               have been applied. Same as: COURSE TO STEER/COURSE
               STEERED, etc. Or whaever term your calculator or
               program uses for the course steered by the compass
               to a destination.

Compass Bearing-- A bearing taken with the ships compass.

Handbearing-- A bearing taken with a handheld compass.

Speed(S)-- The speed of the boat through the water. Knotmeter
		   reading, etc.

Speed Made Good(SMG)-- Speed corrected for the effect of current.

Set-- The direction to which the current is flowing.

Drift-- The speed of the current in Knots.

mi-- Nautical mile(s).

Dead Reckoning Position(DR)-- The position as calculated by
                              Speed/Time/Distance.

Estimated Position(EP)-- The DR corrected for the effect of
						 current.
