"The Youth Olympic Games in general are already a great success," he said.
"There is an amazing spirit and the atmosphere has been fantastic and I think everybody has embraced these Games with a lot of enthusiasm, passion and joy."
"It would have really enhanced my Olympic experience. I mean I already had an incredible experience being in five winter Olympic Games. But to be able to take part in the Games at this level at a young age and to be able to share it with every other nation on earth is an incredible experience."
A lack of wind and a delay in competition meant the prince was not able to see the sailors in action, but he joined his sister, Princess Stephanie, for a cruise to inspect the Singapore 2010 Byte and windsurf courses.
He also offered encouragement to Massimo Mazzolini, Monaco's only sailor at the Games.
"I think it's grand, I have a lot of gratitude towards him for coming out to see me because he has shown interest in the sport," said Mazzolini.
"He said he believes in me and good luck, and that he's sure I'll do well."
