Locate a local trailer dealer / repair shop and they'll find a light weight trailer for you. Take your time modifying it to carry your boat(s) and any other gear you have. Current trailers you see in SK are too short and the wheels are too small for long trips. It takes a little work, but you can come up with something. Mine's a single that carries two mountain bikes as well. A buddy of mine in Baton Rouge had a welder buddy of his modify an old boat trailer to carry 4 boats. It has two "trees" running one behind the other in the center. Each has 4 arms. Works like a charm.
