The women’s senior quad of Cassie Flack, Kayla McCann, Rowena Walker and Amina Martin proved the pick of the field over a 4,200-metre cross.
The Belfast Rowing Club-promoted meeting covered a route from the Odyssey Arena to Queen’s University Boathouse at Stranmillis.
The Portadown rowers managed to complete the final in 17 minutes 41.3 seconds.
Added value to the victory arrived with Portadown’s position in the senior class due to two 18-year-old rowers, Flack and Martin.
However, McCann and Walker remain eligible for junior 16 rowing.
The town rowers’ final honour was recorded with class success in the men’s intermediate single scull.
Samuel McKeown covered the 2,700-metre route in 11 minutes 55 seconds.
McKeown picked up bronze with Ireland under 23s at last year’s Commonwealth Regatta and arrived in Belfast boosted by glory on January 25 at Limerick’s Irish Indoor Rowing Championships.
That Limerick result was achieved thanks to a time of 6 minutes 4 seconds across the 2,000-metre path.
Other rowers representing Portadown took to the water for the single scullers, boys’ junior 16 quad, girls’ junior 16 quad and masters’ VIII.
Next on the schedule in the Head Of The River calendar sits a trip to the Scullers Mini-Head tomorrow (Saturday) before Erne on February 28 and Lagan Scullers across early March.
