If you are anywhere within reach of Chichester this saturday, try the Stockbridge Boat Auction, 10.00am that day - several tenders both rigid and inflatable in their catalogue.
Stockbridge meadow is on the West Wittering Road just as you leave Donnington, half a mile from the bypass - you wont miss it by the crowds!
Pity - it was cancelled, the site flooded overnight. When i got there a Range Rover was trying to extricate a Toyota 4wd, and both were rapidly sinking deeper into the mud in the car park! I think they had to get a tractor down in the end....
Derek (auctioneer) says they may have another go in a months time if it dries out a bit.
There is a new virtual boot sale on the internet where you can sell anything private or trade for free. Take a look at www.kaboot.co.uk there might be something there.
