• the multifunctional board (or multitasking board) 2 of figure 2 or of figure 14 has a hull 22 characterised in that it has a profile that reproduces, for each outer edge of the hull, an ansa lunata 25 and 26 both of which extend along the longitudinal extension direction X of the hull 22.
• the ansa lunata 25 obtained on the lateral profile of the edge of the hull 22 is on the right side along the longitudinal extension axis X, while the ansa lunata 26 obtained on the lateral profile of the edge of the hull 22 is on the left side along the axis X.
• the ansa lunata 25 and the ansa lunata 26 are symmetrical to each other in a mirror-like fashion with respect to a centre-line plane M of the hull 22, the axis X preferably being housed in the centre-line plane M.
• the presence of the two ansa lunata 25 and 26 along the profile of the hull 22 allow to have an optimised, stable and more performing design/shape of the hull.
• This particular design/shape allows to exploit the speed and length parameters.
• the floating line designed with a recess called "ansa lunata” which projects from the external of the profile of the edge of the hull along the transverse axis Y, allows to increase the floating line - with respect to an equivalent board with external entirely identical (like that of figure 1) - with clear advantage in terms of performance.
• the ansa lunata 25 and the ansa lunata 26 determine the smaller dimension of the hull along the extension axis Y.

• one or both ansa lunata 25, 26 are arranged in a substantially central area 19 of the hull 22.
• the presence of the two ansa lunata 25 and 26 also generates the following further advantage.
• the fluid thread 33 flows in the opposite direction along the floating line.
• the fluid thread 33 flows in laminar configuration (linear).
• the fluid thread 34 While, in the advancement direction of the hull 22 along the extension axis X, the fluid thread 34 flows in the opposite direction along the profile of the ansa lunata 25. In this case, the fluid thread 34 must traverse the entire profile of the ansa lunata 25 and, thus, the path of the fluid thread 34 is longer than the path of the fluid thread 33. In this context, the fluid thread 34 must flow, with respect to the fluid 33, at a higher speed (and thus accelerate) so as to meet in point "a” with the fluid thread 33 which instead flows in laminar configuration at a lower speed in that it must travel a shorter a path (linear). The acceleration to which the fluid thread is subjected 34 generates a vacuum and, thus, lesser resistance of the hull 22 along the longitudinal extension direction X thus allowing the multifunctional board (or multitasking board) 2 a better and faster navigation.
• the two ansa lunata 25 and 26 also have the advantage of facilitating the people using the board to stay astride, this being particularly important for example in the case of lifeguards engaged in rescue operations, they allow more comfort when climbing onboard from the water and they also allow people faced with mobility challenges to climb more easily.
