The watercraft has an elongated hollow hull having a pair of integral outwardly and upwardly projecting outrigger wings, onto which are mounted oar mounting devices each having a flat casing attached to rods protruding out of the outrigger wings. The attachment of the casing to the rods is accomplished by means of sockets installed on the rods, which have spherical housings engaged by ball joint portions provided on the casing, to form a ball and socket joint. The sockets are longitudinally spaced-apart on the hull side edge portion, so as to allow the casing to swivel about an axis parallel to the watercraft longitudinal axis. The casing is engaged by a pair of oar members pivoted therein in the plane of the flat casing. A pair of wires interconnect the pivoted oar members inside the casing, to allow pivotal displacement of the oar members only in opposite directions. The rods which protrude out of the outrigger wings are the ends of attachment rods crossing through the hull transversely, thus allowing a secure attachment of the oars onto the watercraft.
