DEVONPORT STEAM FERRY CO. LTD.

The Log describes a red flag with a blue cross edged yellow and then white, the blue broader than the yellow, and white DSFCo lettering. Sea Breezes instead has plain DSFC. An actual flag offered at auction in 2007 provides the basis for D350. Rosanoski allows a possible historical change but suggests that the answer may combine the letter style with DSFC.
