Spirit of Adventure had been due to take its first passengers this summer, but the inaugural sailing was first shifted to November and will now be on 5 February next year.
Sister ship Spirit of Discovery will not sail until 7 March next year and tours are postponed until 31 January 2021.
A Saga spokesperson said: “Over the past few months, we have worked hard to put in place detailed plans to safely return to cruising and have made fantastic progress with all this work.
“Sadly, however, with Covid-19 again on the increase and most countries still not accepting cruise ships, we have taken the decision to extend the suspension of our cruise operations to next year. This includes the postponement of the inaugural cruise of the Spirit of Adventure.
“We are in the process of contacting all our guests to discuss their options, which include rolling over their booking or receiving a full refund. We look forward to welcoming our guests onboard our ships and on our tours as soon as we are practicably able to do so.”
Saga said 2022 cruise bookings were “extremely strong” and showed pent-up demand. Covid precautions mean ship capacity will be limited to 800, with enhanced cleaning and upgraded air conditioning.
