RACE: The timer for vessel racing.
REL: (RELATIVE HUMIDITY) Absolute, relative to another data
field. For example, absolute humidity.
RPM: (ENGINE RPM) Engine revolutions per minute from the
tachometer.
RUD: (RUDDER ANGLE) The rudder relative to another data
field. For example, rudder angle.
SEA: (SEA TEMP) The temperature of the water. Your device
must be connected to a NMEA 0183 or NMEA 2000 device
capable of acquiring the water temperature.
SOG: (SPEED OVER GROUND) The actual speed of travel,
regardless of the course steered and temporary variations in
heading.
TRP: (TRIP) A modifier for another field, for example, a trip
odometer or trip fuel used.
TTB: (TIME TO BURN) The time needed to make it to the
starting line before a race.
TTL: (TIME TO START LINE) Estimated time it will take to reach
the starting line.
TWA: (TRUE WIND ANGLE) The angle of the wind relative to
the water, referenced from the bow of the boat with a port or
starboard angle up to 180 degrees.
TWD: (TRUE WIND DIRECTION) The true direction of the wind
relative to north.
TWS: (TRUE WIND SPEED) The true speed of the wind relative
to the vessel.
UTC: The Coordinated Universal Time.
VMG: (VMG WAYPOINT) The speed at which you are closing
on a destination along a route when navigating.
WND: (VMG WIND) The velocity made good value when
navigating upwind.
XTE: A cross track error.
