Strength in only one arm did present some difficulties so compromises to create a perfect technique had to be adopted.
Team coach and law firm partner Richard Austin said Corson's strong arm had be the outside arm, and therefore the choice of what side of the boat she rowed was predetermined.
"She is unable to control the angle of the blade normally controlled with the other (inside) hand, so she rowed with a square blade," Austin said.
Strength in getting the oar through the water was reduced, but a shortened stroke and an exaggerated shoulder swing went some way to mitigating the problem.
Austin had no doubt that Corson's determination would see her through the event, although it did come with some challenges, he said.
"If Rebecca could maintain her confidence with a shoulder swing, and the others didn't muck it up, she would be fine," Austin said.
And fine they all were. In fact, the crew finished second in the Corporate 8 division ahead of two boats crewed by men.
True, Treadwell Gordon did have a secret weapon.
"I have known Rebecca Scown most of her life and when we asked her to take part in our boat with our own Rebecca she jumped at the chance. We put her in the seat behind Rebecca," Austin said.
But then in rowing, especially in a crew of eight, the individual is only as good as the rest of the team.
"Our team was full of novices, but when you have the enthusiasm x-factor you can do almost anything."
The crew only had five rows in 14 days since they decided to give it crack and the event itself, but Corson's determined attitude has been an inspiration to all at the firm.
"That's what the sport of rowing, and this event, is all about. As far as the crew are concerned, they have already won the prize."
