I just heard that my sailing ex Cherbourg on Friday 4th is also cancelled. I was called before Christmas and offered inducements to re-route via Calais-Dover, as the replacement ferry, presumably Nordica, was smaller and could not carry all the bookings. I declined the offer and asked what would happen if all the people booked refused to re-route. The unofficial comment was that they would probably cancel the sailing. I wonder if this is the 'technical' reason.
