The month was capped with two Holland America Line ships calling on Sept. 30, Zuiderdam at Pier 27 and Westerdam at Pier 35.
It was the first time the 2004-built Westerdam visited San Francisco. The port presented a plaque to Capt. Rens van Eerten to commemorate the occasion.
Westerdam visited as part of a coastal voyage from Vancouver to San Diego, where it was scheduled to begin a seven-night Mexican Riviera cruise. A 15-night Panama Canal cruise to Fort Lauderdale will follow.
