A mainmast (21) has a support base (S) suitable to be fixed to a hull (11) of a sailing boat (1), and an upright (P), which extends along an axis from the support base (S), carries an airfoil, having a leading edge (62) and two lateral surfaces (63a,63b) opposite to each other, and is rotatable about its axis with respect to the support base (S) to position the leading edge (62); said airfoil is defined by a flexible fairing (60), which is arranged in front of a lower portion (P1) of the mainmast (P) and has a first and a second connecting portion (64,65) axially spaced apart from each other; the first connecting portion (64) is coupled to the upright (P) so as to rotate together with the latter with respect to the second connecting portion (65) and twist the airfoil of the fairing (60) due to the rotation.
