is one piece episode 410 filler?

On Amazon Lily, Luffy sets himself back into shape and reminds Marguerite he needs to meet up with his crew. She thinks of how men look and when Luffy asks for help taking the womanly vest off, Marguerite is confused, but nonetheless removes it.

As Luffy prepares to leave, he hopes his crew are still alive and that's all that matters. He also thinks of the horror that Kuma put him through and prepares to get stronger.

He almost hand-walks off the island, but then asks for a ship. Marguerite reminds him the island is on a Calm Belt.

As such, sailors will not make it to the island.
