Personal information/pure curiosity. Not really important. E.g. about a couple of sailing friends, how fast did they sail in comparison to others? Or maybe in which anchorages or marinas someone was? The issue is, that sometime you want to check this out one (or even a couple of) months later. Potentially also great for passage planing, e.g. density report and/or nautical map layers. (Maybe one-off months could work for this but so far I didn't try). Satellite data would rarely be needed. For individual tracking 'YB Tracking' seems better suited than AIS.
