There is much to suggest that it will be a Swedish double victory.
Three-time world champion Emma-Nellie Örtendahl won the last heat of the day and finished second in the opening race behind table three Jasmiin Ypraus, Estonia.
Örtendahl has nine points in that fight.
Up to Borgström in the gold place, there are also nine points.
Samuel Johansson is in the bronze place in the sitting class Runabout GP1 before the last heat.
Johansson was fourth in today's final heat.
The World Cup final ends on Saturday.
