The ceremony will take place in April 2022 beside Tower Bridge ahead of the vessel’s inaugural sailing from Portsmouth.
Mario Bounas, Swan Hellenic’s vice president of global marketing, said: "As a heritage British brand with a global cultural cruising outlook dedicated to taking guests to ’see what others don’t’, there could be no more fitting location to showcase our recent achievements and second ship to our partners in the UK.
"This event will enable us to achieve what we had intended for our first ship, SH Minerva, which will now have a much smaller christening event at the Helsinki Shipyard in November, mindful of the continuing need for caution to protect our staff and guests in these still uncertain times."
