Proposals for a new Fijian flag from 2015. The process of changing flag has since been terminated.

I really like 55, but I'm just a fan of sailboats. I'm not a flag expert, so I'm not aware of the design constraints and expectations surrounding a flag.
The only real rule that it breaks is that it should be easy to draw and it shouldn't have details that get lost when it's viewed up on a flagpole.
