Phill Brander's, or a variation, gets my vote at this stage.

While the fox is quite good it reminds me of an airline we have (or had) in Australia called Emu airlines. The emu of course being a large flightless bird. The fox not particularly aquatic.

The fox is also a very destructive feral pest in Australia so I have an natural emotional opposition to it.

That said, I'm not too bothered either way by logos.
