Not quite that long, but the Norwegian national broadcaster NRK did a week-long trip one one of the coastal shipping routes in the nortern part of the country. Might be of interest for you. I know they used to offer the whole thing as a torrent, but it can also be found here: https://tv.nrk.no/serie/hurtigruten-minutt-for-minutt
