Luxury superyacht the Equanimity has docked at the Boustead Cruise Centre in Port Klang.
The 91.5m-long vessel appeared on the horizon of the centre's jetty at about 12.25pm, tailed by a marine police vessel.
"That's RM1 billion on water," a journalist at the scene said as others looked on in quiet awe.
A Malaysian flag was seen hoisted on the Equanimity's mast.
