"The default red ownship is "Default"
If you want to replace it with your own picture, drop ownship.png there as said in paragraph 3 of User Icons | Official
OpenCPN Homepage"
The point is the default ship_red.png does not display anymore, and there's nothing I knowingly did to change this. I copied the file to /home/android/.opencpn/UserIcon and renamed to 'ownship.png' Selected 'Default' in Ships settings, applied and exited the module with 'o.k.'. Even quit and restarted
OpenCPN. Now the tiny circle has changed to a tiny solid dot... Go figger.
