Brittany Ferries will not run any services between Guernsey and Poole for a month this autumn.
The operator's timetable shows no ferries between the two ports from Monday 3 November to Thursday 4 December.
It is reportedly due to routine maintenance work on the Voyager vessel, but regular services will continue to run to Portsmouth and St Malo.
The last return trip before the four-and-a-half-week pause is on Sunday 2 November, leaving Guernsey at 10am and landing in Poole at 1pm before heading back at 2:15pm.
The route will then resume on Friday 5 December with a 10am ferry from Poole and the return 2:15pm service from Guernsey.
ITV News has contacted Brittany Ferries for comment.
