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. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=--=-= =-= TO UNSUBSCRIBE, send this message to majordomo@ronin.com: =-= =-= navigation =-= =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=--=-=
