At Centurion details matter. Adequate storage, plentiful stainless steel cup holders and elegant upholstery were all taken into consideration when developing C4 seating. C4 seating is part of Centurion's revolutionary I.C.S. uni-body construction system. Unifying the seating with the substructure and hull gives you the smoothest ride in the industry. C4 seating is a perfect blend of form and function for your boat's interior.
