The invention relates to a vertical axis and transversal flow nautical propulsor with continuous self-orientation of the blade comprising a plurality of blades (1), rotating about a vertical axis and supported by a blade (1) supporting plate (2), also said plate (2) rotating about a vertical axis independently with respect to the rotation of the single blades (1), characterised in that it further comprises a motor (4) of the rotation of said blade (1) supporting plate (2), a fixed pulse electric motor (10) for each blade (1), for the rotation of each of said blade (1) about its own vertical axis, a rotating shaft (17), supported by rotor body (3) coupled with said blade (1) supporting plate (2), upon which spindles (15) are provided, coaxially one with respect to the other and with respect to the shaft (17), and independently rotatably coupled with said rotating shaft (17), the number of said spindles (15) corresponding to the number of the single blades (1), said spindles (15) rotating independently one with respect to the others in such a way to allow the rotation of the relevant blade (1) independently with respect to the others, said rotating shaft (17), and the spindles (15), having one end within said rotor body (3) and one end outside said rotor body (3), on said inner and outer ends of each of the spindles (15) first motion transfer means (14, 18) being provided, to transfer the motion from the relevant electric motor (10) to the relevant rotating blade (1), on the blade (1) axis and on the axis of the relevant electric motor (10) corresponding motion transfer means (12, 20) being provided, to transfer the motion to said first motion transfer means (14, 18), and one interface unit between the operator and a propulsor control electronic unit (32), said electric motors (10) being controlled by said electronic control unit (32) in such a way to adjust the position and the orientation of the relevant blade (1) in order to obtain for any operative situation the best performances for the whole operative range.
