ok, the website is a little obnoxious, but the Shore Spike from SlideAnchor.com (http://www.slideanchor.com/spike.asp) looks pretty handy. Basically its a spike with a sliding handle that allows you to pound it in to the ground for shore ties. I would prefer something like an entire forest if I was leaving my boat unattended but the smnaller version look pretty handy for the dinghy.
