is one piece episode 47 filler?

Alvida and Buggy sail towards their next destination, focusing on relocating Buggy's crew. The Buggy Pirates, having been repelled from Orange Town by the townspeople, fled from the island taking Buggy's body parts with them.

Assuming Buggy to be deceased, they host a funeral for him on a separate island, where Mohji and Cabaji get into a dispute over who would replace Buggy as the crew's captain. Mohji and Cabaji engage in a duel for the captain position, which lasts several hours and into nightfall.
