Two parallel masts (2) positioned in a plane perpendicular to the median axis of the hulls (4) are connected together near their top by a rigid connection boom (1). The boom is articulated at its ends on the fastening points to the masts. The whole of the rigging is fixed to the portico constituted by the two masts and their connecting boom. Two shrouds (3) are tensioned between the masts and a stay (5) fastens each mast front to the prow of each hull.
