Anyway, Sanji isn't Vice Captain because IRL pirates normally don't have those.
Quartermaster is typically second in command followed by first and second mate.
If you look at what duties a Quartermaster does..
-Control and command when Captain is not around.
-Protector of the crew under captain.
-Although not the navigator, skilled in navigation as a secondary and supervisor of helmsman.
-Sorts supplies and treasure, worries about financials and food stock.
If you take Sanji and Nami as a team their skills together make up Quartermaster.
Sanji protects, commands, strategizes, has navigated and done ship handling, supervises Jinbe at times, and deals with inventory.
Nami navigates, sorts treasure and supplies and has supervised.
The only thing Zoro matches for Quartermaster is protect at times and dealing out punishments.
