Sapphire joined the Saga fleet in April 2012 and spent eight years in service.

It will re-enter service in 2021 as Blue Sapphire, sailing under the banner of Anex’s new cruise operation.

Due to the coronavirus pandemic, Saga was unable to give Sapphire its planned send-off.

Guests and colleagues are instead being asked to each complete a 2.6 challenge to reflect the 8,050 nautical mile trip the ship was due to sail for its farewell cruise.

The 2.6 challenge is a fundraising effort requiring participants to complete a challenge linked to the numbers two, six, 2.6 or 26, or any variation on the theme.

Details of the challenge will be shared on Saga’s Facebook page in the coming weeks.

“Saga Sapphire has been hugely popular with our guests over the past eight years," said Nigel Blanks, managing director of Saga Cruises.

"She will be missed, but we’re delighted she will be playing a starring role in Anex Tour’s new cruise offer.

"Launching Sapphire was an important moment, and laid the foundations for our purpose-built boutique cruise offer. We are now looking forward to an exciting new chapter for Saga Cruises as we prepare to welcome the Spirit of Adventure to our fleet in the coming months.”

Neset Kockar, chair of Anex Tour, added: “I am thrilled to have our first cruise ship which is getting prepared to sail in the eastern Mediterranean after a thorough renovation.

"Expanding our product range in line with the needs of our customers has always been a top priority, and it is my pleasure to offer one of the most unique experiences to them.”
