When we went to Waikiki Yacht club the last time I saw this kids practicing their little sailboats, I really do not know what this sport really called. But they are so fun to watch cruising with their tiny boats at the heart of Waikiki Yacht club harbor. They seem like playing Polo or something, they have their coach whistling and about 12 tiny sailboats are participating. I am sure tey are having great fun.
