size of courtesy flags and boat

[In Training]

what size are your courtesy flags and how large is your boat. I have 49 ft sailboat with 64 ft mast height from water. All I see are 12 x 18 courtesy flags sold on line. Have to wonder what other boats my size are using, regardless of international recommendations.

Courtesy flags are pretty much sold as a set size.
I just measured ours, it's 12 by 18
We are a 42' cat, 63.5' mast

12x18. 44' 33 tons. Hey, you can see it clearly on the boat at anchor. That's the courtesy.
