"I drew my national flag and, of course, the gold medal, because I really want it," said windsurfer Kiran Badloe (NED).
"I tried to draw the silver fern, a symbol from New Zealand that means new life, and the same symbol the New Zealand team (members) wear around our necks on our Maori necklaces," said Byte sailor Elise Beavis (NZL).
Sailors crowded around the mural when the day's racing was delayed in the morning because of the lack of wind.
"It's better than the waiting, as we are always waiting," said Estonian Nikita Rom who competes in boys windsurfing.
"We drew the sun, the rainbow, and we also drew the boats we usually sail in," said Portugal's Ines Sobral, who combined her artwork with fellow girls Byte sailor Constanze Stolz (GER).
The murals will be displayed at the Youth Olympic Village.
