Croatia & Greece Digital Nomad Visa

[LTshaw]

Has anyone managed to get either of these visas while providing your sailboat as your address?

Are these countries open to this as a valid "address" when applying for their digital nomad visas? I can't seem to find any info on this specific case. We could always try and provide an address, but the reality is, we're going to be sailing their waters and not really at a permanent address.
