The course itself is an archipelago race, having the starting and finishing line at Kruunuvuorenselkä, west of Vasikkasaari. From there the course will continue passing Katajanokka, through the Särkkä passage and further around Pihlajasaari, coming back by passing the Ryssänsaari from the north and further around Lonna back to Kruunuvuorenselkä. The bigger boats will also sail around the Kuggenstein sea mark (marked with a dotted line on the map below). The length of the race is either 13 or 16 NM. Depending on the wind, the race will be sailed clockwise or anticlockwise.
