At that time the Zuiderzee had an open connection with the North Sea. The sea water was salt or at best brackish. Waves could be steep and short due to the shallow waters.
In 1932 a dam was built between the North Sea and the Zuiderzee and the Zuiderzee was called IJsselmeer. As result of this the lake contains fresh water. Inside the lake new land was reclaimed. At this moment the center of the 1928 6 and 8 Metre course is located in the city of Almere. Also the city of Amsterdam reclaimed land from the sea and moved towards the lake. When the sailors from the 1928 Summer Olympics could return to their venue they would hardly recognize it.
