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.
