First and foremost tinycorelinux runs almost read-only on an SD-card. When switching to raspi-os you might want to add an UPS and a power cycle script to prevent SD-card failure. If you want to test with raspi-os on a pi-zero2 I'd suggest you install OpenPlotter, inclusing pypilot, and remove OpenCPN (and X).
How much less power did tinylinux use compared with raspi OS?
Surprisingly the Zero pulls more power when the desktop is turned off in raspi-config. Run startx in the terminal & power goes down a little.
Need to do some more testing though to check that. Seems odd.
Not sure read only helps much, usb sd caed readers use more power (ssd even worse) so infuxdb data all goes in the internal card. If (when) it wears out they cost little these days.
From obsessive data logging it looks like it could well be worth a arduino nano or similar to read the many nmea0183/serial data going into siganlk instead of many serial/usb converters.
