Fully Supported
The bimini is fully supported by framing fore and aft, then there are the straps that hold it down which are connected to the cabin top hand holds and the stern rail seats.The bimini is connected to the arch through a tube and plastic insert setup. The plastic insert has a zipper that the actual bimini is attached to. So far, no rain through the connection, very dry in the cockpit during rain.If the one you saw was rigged the same way as the one's at the Dallas boat show, they were just in place to show the overall effect and not the actual mounting.Regards.Bruce.Neon Moon
