is one piece episode 64 filler?

The Straw Hat Pirates travel along with Miss Wednesday and Mr. 9 in the Going Merry to get them to Whisky Peak. Nami is surprised by the weather condition on the Grand Line because it changes randomly and drastically.

She tells the crew that they are heading in the wrong direction and the crew follow her orders so they can get to Whisky Peak. The Straw Hat Pirates arrive at their destination, while Miss Wednesday and Mr. 9 get off the ship and start swimming immediately after they see Whisky Peak.

Nami says that it is impossible to get off the island unless the Log Pose settles down.
