When in port, complaints are not uncommon from other vessels.

You need to do a podcast, Ship Talk with Rubycon
Depends on ship but can cost $250 on a seven day voyage.
I do have a youtube channel and may put some stuff up there. The new system supports livestream but I don't think they'd like that.
