Years ago I saw a trailer backup pole that rotated to the vertical as ski was floated off trailer, up that rotated down as the ski was moved onto bunks. It was a commercial item.

As I recall it was a fiberglass pole attached to a bottom weighted ring that went around the rear trailer support beam. This allowed the flag to rotate to the up when the craft was floated off, and then it would rotate down when the pwc was bunked.

I knew I should have asked about it at the time but was not able to... Anybody seen this item and can provide the manufacturer/source? Yeah, I can have such a thing made, but if it is already out there then that will be easier.
