Data availability

This session logged 0 underway samples with valid wind and boat-speed data — no true wind readings, no detected tacks or gybes, and no polar performance samples were computed for this file. The GPS/instrument log spans 2026-07-15 19:46–21:30 UTC, but the boat apparently never sustained the minimum 1.5 kn underway speed used to filter out dock/mooring noise, or the wind instruments weren't providing valid readings for this session.

No coaching analysis can be produced from this data set — there's nothing here to distinguish a slow practice sail, dock time, or an instrument issue. If this was meant to be a working practice session, it's worth checking the NMEA2000 network and B&G wind instrument connection were live before the next outing.

Coaching priorities

None — insufficient data to identify any.
