Abstract

An oar is described suitable to be used in wind-surfing which, on one end, or blade, has a pair of blades (3, 3a) pivoted on the said end (2), rotating essentially about the longitudinal axis of the oar. Means (7) are provided which limit the moving away stroke of the blades (3, 3a) and means (9) which prevent the blades from coming into contact with one another.
