30minutes.The distancespacing between track points can be set to 0.1nm,
0.5nm or 1.0nm. The interval default is a distance of 0.1nm. The maximum
track length is 750 points. When the track has reached this length, thefirst

Settinga short time interval between track points is best suited to navigation
withina close or complex environment, e.g. an estuary or marina whereas,in
contrast, a greater distance intervalis best suited to a long haulvoyage.
