In the eastern European countries, the OK was the official youth single hander and after the breakdown of the socialist system, many 'old' sailors came back to the class of their youth, now with their own boats instead of club-owned.
OK-jollen blev den officielle ungdoms-enmandsjolle i mange østeuropæriske lande efter bruddet med det socialistiske styre, da mange “gamle” sejlere vendte tilbage til den klasse, de havde sejlet som børn, nu i egne joller i stedet for klubejede.
