A windsurfing board may include an elongated hull having an upper deck side, a bottom side, a geometrical midpoint on the bottom side, a geometrical axis x extending through the midpoint and along the length of the elongated hull, a geometrical transverse axis y extending through the midpoint and in a direction that is perpendicular to the axis x, and a geometrical vertical axis z extending through the midpoint and in a direction that is perpendicular to both the axis x and the axis y. The hull may include one single hull body. The windsurfing board may also include a universal joint and at least one lateral resistance inducing projection projecting from the bottom. The bottom side of the windsurfing board may be symmetrical around the axis y, so that the parts of the bottom side that are divided by the axis y are mirror images of each other.
