hi,
it seems that the day was a bit windy (wind from south).
When flying"out" (from around 7 min 30 sec to 9 min) you was using sport mode and the drone was at a speed of 10-14 meter per second. (~26-29mph)
After re-connection with the RC and...
Did you calibrate the compass?
It’s not in the manual but DJI says it works on neo too

But hand-catching an uncommanded M300 on a boat still have substantial risk.
I do not know how to best describe water condition. Let's just say the drone measures level 4 wind in Beaufort Scale (20-30km per hr) during the flight.
