Oxford University Womens' Boat Club (OUWBC) is a club for female rowers and coxes of either sex who are students at the University of Oxford. The aim of the club is to field two VIIIs to race against their counterpart from the University of Cambridge at the Henley Boat Races, held in March or April over 2000 m on the Henley Reach. The First VIII receive university blues, and are therefore more commonly known as the Blue Boat. The Second VIII receive university colours, and are commonly referred to as Osiris.
