Customization

Press and hold on the parameter to change it. The following options are available:

Boat speed

Water speed from NMEA sensor (if NMEA VHW data is enabled). Otherwise boat speed will be equal to GPS speed (SOG).

Graph displays speed changes in 6 minutes time.

Speed Over Ground

Velocity Made Good in the direction of the next mark. Not the same as VMG, which means velocity made good against the wind direction.

Magnetic boat heading from NMEA sensor (if NMEA VHW data is enabled). Otherwise GPS course (COG).

Due to leeway and or current/tide course over ground (COG) may be different.

Graph displays heading changes in 6 minutes time.

Course Over Ground

Course Deviation from the previous mark.

Distance from your ideal course line.

Deviation from your heading at this moment.

Bearing to the Mark.

Angle to the Mark relative to current course.

Distance to the mark.

Time to Layline is calculated according to your speed average, course average and wind direction average.

Shortest distance to the startline

Distance sailed from the start

Sailing duration from the start

Target boat speed and efficiency according to polar.

Apparent wind speed and direction.

True wind speed and direction.

6 minutes true wind direction and speed graph.

1 hour true wind direction and speed graph.

Current speed and direction. Calculated as a difference of two vectors 1) boat speed/heading 2) GPS SOG/COG.
