KTH Sailing Society, KTHSS, was founded on December 11, 1963 and is an union association under the Technical University Student Union (THS).

The association is open to students or already graduated students from KTH, and THS staff. Our purpose is to take advantage of the members interest and to promote increased interest in sailing at KTH. We arrange and participate in a number of races every year, as well as organize courses and other activities.
