If you want to restore something, go to the nearest marinas
and ask the managers - you might be lucky and actually get a boat for free - as long as you promise to take her away from their plot.
If you are good at searching the Internet
I remember about a year ago I stumbled upon a site where there were give away boats - by owners who could not or did not want them anymore. I believe with some skill and asking around you may find this website again.
