The $160 million, 317-foot superyacht Vava II docked at the Port of Astoria Saturday, providing a grand spectacle but declining to take part in the High Water Boat Parade.

The Port of Astoria hosted the 33rd largest yacht in the world Saturday, as the 317-foot, $160 million Vava II docked at Pier 1 for maintenance on its way down the West Coast toward the Panama Canal.

Swiss-Italian pharmaceutical entrepreneur Ernesto Bertarelli, worth more than $12 billion, commissioned the yacht for his wife, Kirsty, a 1988 Miss UK and herself one of the richest women in Great Britain. The yacht was complete by March 2012.

Built by Devonport Yachts in Plymouth, England, by 200 laborers in secret under the title Project 55, it’s reportedly the largest such craft ever built in the U.K. It features a helipad, a swimming pool that varies in depth based on swimmers’ preferences and a back end that folds down into a beach club. The nearly 4,000-ton yacht cost more than $400,000 to fill the gas tanks.

The Vava II was intended to replace the couple’s older boat, which only measured 154 feet.

The Vava II left early Sunday morning and headed south. As of late Monday night, it was just south of Eureka, Calif., motoring on its way to Balboa, Panama, on the eastern side of the Panama Canal. It’s flagged for the Cayman Islands and homeported at George Town on Grand Cayman, as are a large number of the world’s superyachts.
