I'm not sure but it may be due to how you specified runtime version.  Remember the "runtime" in this case is OpenCPN. 
It looks like you set the runtime-version to the version of org.freedesktop.Sdk instead of OpenCPN.

runtime-version: 1.6
sdk: org.freedesktop.Sdk

should probably be this instead (unless you set some other branch with --default-branch option of flatpak-builder when
building OpenCPN)

runtime-version: master
sdk: org.freedesktop.Sdk//1.6

You can check the version of OpenCPN with 'flatpak list -v'.
