Thanks for your insight, and all the information you share here. I've seen nothing about the incident on the roll calls on this site, although I was able to hear through a Facebook group from a passenger who was on the Tor when it happened (last night of their cruise). She indicated that Viking had told them nothing about what had happened and the news article you posted was the first reliable information they had received. It does appear that the Tor is still making its way to Budapest, as scheduled, so hopefully it won't present a problem for anyone.
