Hey EP, I saw that picture too, and yes I will give you, that is a big frikkin' flag on
Yamato. Biggest BB ever built. Pride of Japan. Named
Yamato for cryin' out loud. I can promise you, her sea trials were a big-time photo-op.
But you do the math: OK, I will.

In the photo, on my monitor, that flag on
Yamato is 3mm long, the waterline of the ship is 140mm. The flag is about 2% of the waterline length of the ship. Keep in mind, we have both agreed that that is one BIG flag. The Kinai Maru on the website's flag is 1.7% of waterline length. Shokaku, a fleet Aircraft Carrier, flies a flag that is 1% of the length of the ship. The ones on the Marus in the video are 8mm long on a 138mm ship, roughly
6% of the waterline length. Am I to believe that (in relation to the size of the ship, which is how one determines the size of the flag a ship flies) a lowly Maru would dare to fly a flag
three times the size of the one
Yamato flew during her sea trials?
Six times the size of the flag flown on a fleet Aircraft Carrier? Outrageous! The Maru Captain who flew such a flag from his mast would be relieved of his command and laughed out of the merchant marine for being such a buffoon. It flies in the face of all military/naval courtesy, not to mention operational security, good seamanship, and common sense!
The ultimate proof? I showed the new video to my
wife, without telling her about this debate. First words out of her mouth? "Aren't the flags on those ships a little big?"

Arrrgh! Take that!
I respectfully submit that those flags should be 1/3 of their current length
or less in order to be realistic. Even make them slightly bigger to make up for limitations of people's monitors, I'm not opposed to that, but as they are, they are
waaaaay waaaay too big! They look preposterous!
Respectfully,
Mylander
