The barge "Onrust", built in 1915, is the last of a series of four barges with almost the same dimensions. These barges had a very good reputation with yacht owners. The line plan of "De Onrust" was therefore a model for the construction of a ship named "De Groene Draeck" for Princess Beatrix. After the war, more Lemsteraken were built, with minor deviations, because "De Groene Draeck" may not be copied just like that. This ship is spacious and has a cozy cabin because of the oak paneling. Outside the deck there are also seats available to optimally enjoy the SAIL spectacle.
