Viking River Cruises set a record Wednesday, simultaneously inaugurating 10 190-passenger Viking Longships for European cruises.

The main ceremony took place in the Amsterdam Harbor, where four of the ships were located. The other six were at the Neptun shipyard in Germany and were christened via satellite.

The ceremony was certified by a Guinness World Records adjudicator as “the most ships inaugurated in one day by one company.” Only eight of the ships counted toward the record, however. Guinness did not include two ships that entered service in 2012 but were not christened until Wednesday.

The ships are the Viking Aegir, Viking Atla, Viking Bragi, Viking Embla, Viking Forseti, Viking Jarl, Viking Rinda, Viking Skadi, Viking Tor and Viking Var .

Viking, which has been on a building binge, says it will break that record next year with the launch of 14 ships.
