is one piece episode 244 filler?

Franky is shown watching Usopp fix the Going Merry from afar with Mozu and Kiwi. Usopp is then shown remarking about the weather becoming rough as he patches the ship.

Franky then remembers Usopp's determination in getting the 200,000 belly to fix his ship. Mozu mentions that the ship must be what he needed the money for, and Kiwi notes Usopp's ignorance in the weather.

This causes Franky to say that Usopp's plight in fixing the ship is a lost cause. As Franky approaches the ship he repeats his comment about it being useless loud enough for Usopp to hear in order to reveal his presence.
