All Condor Ferries passenger sailings have now been suspended until mid-June.
The Rapide won't sail until 14th of next month, with the Liberation and Clipper off until June 12th.
Condor says it's because of ongoing government advice restricting the movement to and from the Channel Islands, France and the UK.
Refunds are being offered, but the ferry company is encouraging travel vouchers instead.
"Due to ongoing government advice restricting the movement of people to and from the Channel Islands, France and the UK, all passenger sailings are suspended up to and including 14th June. In the interest of public health, we have had to react to these restrictions; we are sorry for the change to your trip.
"Everyone affected by the suspension will be offered a rebooking or travel voucher which is valid for 18 months.
"Our contact teams will be extremely busy during this period and ask for your patience due to the unprecedented changes to the schedule." -Condor Ferries statement
