... interesting point, I suppose, for all owners or "trailed" Ribs, towed by sub 3.5 tonners, in excess of 7.0 Metres long. How do the trailer builders adequately support the transom and keep within the 7.0 plus drawbar rule? If the bow of the boat rests on the winch post, I believe it is assumed, at least by some Police forces, that that is where the trailer starts. If your boat is then significantly over 7.0 metres in hull length, how is the transom supported.. after all it's carrying the weight of the engines in the case of outboard rig...? Just curious really....
