As for quality, you get what you pay for. If you really want good quality, you likely want a wool blend fabric
with excellent seams. That's jolly expensive.
Flags that last 3 months in the tropics are more affordable. Fully synthetic.
As for size, I note your vessel is 40 feet. The old rule
of thumb of 'an inch of flag for each foot of hull' would suggest you fly a national flag that is 40 inches long.
And if you're cruising any nation that takes pride in itself, you'll find that locals will feel a wee miffed if you're flying, as a courtesy flag, a tiny duster compared to your national flag.
as an example. Indonesian officials will show no flicker or emotion, but if you're flying a tiny 18" Indonesian flag on your starboard shroud
but a 40" Aus ensign from your stern, do not expect them to do you a favour.
YMMV, of course. Frank Zappa noted that anything less than 8" just doesn't count: https://www.azlyrics.com/lyrics/fran...dimension.html
