Digitally recording boat data

[Cyrus Safdari]

I've been working on programming my own NMEA 2000 network interface and setting up a Raspberry Pi on-board and using data recorders like the Voyage Recorder by Yacht Devices (no association) to collect and record (and transmit) a variety of data autonomously including GPS, AIS, barometric press, temperatures (engine, water, fridge, interior and exterior) etc etc with local processing and analytics but I would really like a way to digitally measure and record boat movement - roll, pitch and yaw. Any ideas? Tips or suggestions or experiences appreciated. I'm not familiar with this sort of thing in the marine industry context so maybe you guys are more fmiliar with what's out there in the marine market

EDIT: I'm looking at this multisensor board which has a built-in 3-axis gyro. magnetometer and accelerometer plus power converter

Order a mpu9250 and load openplotter onto the Pi, then everything is in signalk, easy to save to a database.
I use sqlite and node-red to save everything once a minute. Works great
