The classifications were developed and current as of March 2011.
[1] Rowing Australia defines this classification as "athletes with a visual impairment (LTA-B1, LTA-B2 and LTA-B3)" [1] Rowers in this classification compete in single and sculls for club, state, and national competitions.
In international competitions, they compete in mixed cox fours sculls, with a maximum of two visually impaired rowers in the boat.
[1][2] Classification is handled by FISA – International Rowing Federation.
[3] Australians seeking classification through Rowing Australia as a visually impaired rower need to provide evidence of having been classified by an International Blind Sports Federation (IBSA) classifier or an Australian Paralympic Committee vision impairment classifier.
