Seabourn says it has "proactively" cancelled voyages for three of its ships beyond its current global operational pause.
Seabourn Encore, Ovation and Sojourn are set for longer lay-ups, beyond the line’s planned return in November.
All sailings onboard Encore have been cancelled up to 25 November; Ovation, up to 20 December; and Sojourn, up to 24 May, 2021.
The line initially paused global operations on 14 March, which has been extended several times through to 20 November.
"The decision to cancel additional voyages is a proactive action to deal with the circumstances continuing to evolve from the global response to the Covid-19 situation," said Seabourn in a statement.
“We’ve been saying for some time that our resumption of service will come gradually, and this action reflects that discussion," said Seabourn president Josh Leibowitz.
"The health, safety and wellbeing of our guests, crew and the people in destinations we visit remain a top priority.
“Like many who watch the travel industry, we are encouraged by the signs emerging around the world that point to travel’s progress toward return.
"When our expert science and medical advisors and our destinations support the ability to resume travel on Seabourn, we’ll be ready.”
Cancellations and changes to voyages will be communicated to guests and/or their agents in date order of departure.
Guests booked on Seabourn Sojourn’s 2021 World Cruise will be automatically reaccommodated in the same suite on Sojourn’s 2022 World Cruise, at rate paid, within 30 days.
Bookings for other impacted cruises will automatically be cancelled; guests will receive bonus future cruise credits. They can also request a full refund of monies paid.
Future cuise credit is valid for 12 months from date of issue and may be used to book sailings departing through 31 December 2022. The amount of non-cruise fare purchases may be transferred to a new booking.
Alternatively, guests may request a refund of the monies paid to Seabourn, which will be reimbursed to the original form of payment.
Seabourn has asked guests and agents to use online support resources before attempting to call the line owing to lengthy call hold times.
