It comes as the line reports growing demand for summer 2021 departures and beyond.
The luxury line has extended its programme to all voyages departing before April 30, 2021.
Originally launched in early March, the programme lets guests cancel their cruise for any reason up to 48 hours prior to sailing and receive a 100% Future Cruise Credit for the amount paid. The credit can be redeemed up to two years from the date of issue.
When guests opt for a credit and have paid in full, the cruise line is protecting commission on both the cancelled booking and the future reservation when the credit is applied.
Loyal members of the brand’s Venetian Society, were showing “the greatest propensity to book”, Silversea said.
Silversea said sailings closer to home were proving popular with British guests booking the Mediterranean and northern Europe, while Americans are booking Alaska.
The line believes expedition destinations such as the Galapagos and Antarctica will rebound strongly.
Peter Shanks, Silversea’s managing director for UK, Ireland, Middle East & Africa, said: “There are definite green shoots ahead as our regular cruisers yearn to get back to sea. Proving most popular are our ‘closer to home’ destinations in the Mediterranean and Northern Europe.
“Silversea is also benefitting from its leadership in the more remote destinations with a focus on wildlife and nature, including Antarctica and the Galapagos, which are proving to be more appealing than ever. Extending ‘Cruise with Confidence’ continues to demonstrate our commitment to our travel advisor partners, as we continue to protect their commission in the event of cancellations.”
Silversea is offering reduced deposits of £750 per suite on any new booking made before August 31. Guess who redeem this offer will also receive £1,000 onboard credit per suite.
