That is the auction I went to. The inflatables were old, to say the least. I think two were Avons. A third, the newest, looked like a West Marine (PVC), the reinforcing on the bottom of the transom was starting to come off. A fourth one was deflated and wasn't a brand I was familiar with; it looked sad. The fifth one was a plastic toy. The West Marine one sold for around $200 I think. One of the Avons sold for under $200.
One of the Ericsons, I think they were both 27's, sold for about $2,500. Everything else sold for between $150 and $850 or so. The one big power boat (sorry, didn't pay much attention to it but it looked to be in fair shape) sold for I think $200 or $250.
The best that could be said about most of them was that they were still floating.
There were several lots of multiple items of miscellaneous junk (old fenders, anchor rode, etc) that were selling for $5. As I was leaving the parking lot I saw people throwing the stuff from those lots that they didn't want in trash cans and keeping what they did want.
