is one piece episode 747 filler?

The Going Luffy-senpai sails through the New World, and the Barto Club eagerly treats the Straw Hat Pirates to a feast. Suddenly, large chunks of hail start falling, and Bartolomeo tells the Straw Hats to get inside.

They refuse, wanting to help, and ask where their navigator is. The Barto Club reveals that they have no navigator, and they just call their granny back home if they need any help.

Gambia calls her to ask about the hail, but to the Straw Hats' shock she only gives domestic advice like getting gum off the deck and treating lumps caused by the hail.
