A high speed powerboat hull (100) incorporating a tunnel ventilation channel (154) spanning between a starboard (160) and port (162) side of the hull (100). The hull (100) has a V shaped forward section. The ventilated tunnel (150) is provided as a recess having two substantially vertical sidewalls (152) arranged parallel to each other located along each of the two outer edges of the tunnel (150). The tunnel (150) is disposed longitudinally between the ventilated channel (154) and a transom (112). The ventilated tunnel (150) is in fluid communication with the ventilation channel (154). The hull (100) can further comprise at least one stepped hull section (122, 126).
