Improved mast for boats, characterized in that, essentially, it is constituted by a tubular structure in the general shape of an ellipse, which has one of its vertices provided with a substantial axis of rotation, comprising a tubular guide frame for the sail arranged in a perpendicular direction to the mast, including reinforcement tubes that arise from the sides of the latter converging in one of the tubes that form the guide for the sail, so that said mast is capable of rotating movement on axis to adopt different positions of relative orientation.
