It is considered the world's premier indoor regatta attracting adaptive, able-bodied and coxswain (non-rower) competitors from around the world.

Competitors rowed against the clock on Concept2 Model D Ergometers at Boston University's Agganis Arena.

This is the second year adaptive rowers were invited and after 37 competitors participated last year, 63 adaptive competitors took part this year.

United States Paralympics event coordinator Kallie Quinn said she was pleased with the turnout of the event.

"This was the second year for the inclusion of the Adaptive Divisions and we in the US Paralympics Emerging Programme were very excited to be part it again this year," Quinn said.

"The event gives our emerging and developing rowers a chance to test their stamina, skills and mental toughness against other competitors."

Adaptive athletes raced the 1000 metres in the Paralympic rowing categories for Open Men and Women as well as in a Functional Electrical Stimulation category.

Paralympic events were also offered to junior men and women.

Top finishers for the US included Christopher Champion who placed first in the open men trunk-arms division with a time of 3min 58.5sec and Eric McDaniel who placed first in the open men legs - trunk-arms; physically disabled with a time of 3:08.1.

Champion is affiliated with the Center for the Intrepid at Brooke Army Medical Center and McDaniel rows for the USA Rowing's adaptive national team.

Also performing well for the US were Anthony Radetic who placed first in the open men arms-shoulders category with a time of 4:46.4 and Matthew Anderson rowing for the Center for the Intrepid at Brooke Army Medical Center placing fourth in the open men legs-trunk-Arms; physically disabled with a time of 3:26.1.

The objectives of the event for US Paralympics were to reach out to all identified and developing/emerging military rowing athletes and provide introductory sports competition experience in rowing.

Quinn said she was satisfied with the execution of the event.

"The partnership with Concept 2 and US Paralympics worked out well to help expose our developing athletes to a great event and get a chance to compete."
