Both Baker-Hogan and Rush were preparing for individual competition at the NZ Masters, being held at Lake Karapiro this coming weekend, which a solid Whanganui contingent will be attending.
Third was Star RC's Kyle Malone in the club rower grade (88.9 per cent for 36m 58s), while Star and Clifton RC crews finished fourth and fifth.
"The singles ruled the roost, if you will, in the conditions," said Jacs Rush.
"Fantastic water for it, because the tide was going out. Three kilometres up and 6km with the tide."
The Star RC pair of Valerie Chan and Vanessa McCormack surprised spectators as they came to the side of the Whanganui River midway through the race.
"A Star women's club double snapped an oar, opposite the Aramoho rowing club," said Rush.
"They were helped in and borrowed an oar, so they finished."
The sixth and final race of the Winter Series will be the 10km race, which is also the Dick Tonks Trophy event, on October 9.
