The arrangement is characterized in that a rear end (22) of the chamber (20) comprises an outwardly curved protrusion (23) extending into a corresponding inwardly curved cavity (66) formed at a front edge (63) of the rudder (60), and that the rudder (60) comprises a cone (67) having a base and an apex (A1), the base of the cone (67) surrounding the inwardly curved cavity (66) at the front edge (63) of the rudder (60) and the apex (A1) being within the rudder (60) or beyond the rear edge (64) of the rudder (60).
