Ben,

Hurricane Island Outward Bound School does sailing courses in Penobscot Bay, Maryland and the Everglades. Their website is www.hurricaneisland.org. I''m not sure if thirteen might be under their age requirements, though. I happen to know of a group in the UK called the London Sailing Project whose aims are pretty close to what you describe. Their website is www.lsp.org.uk and they sail three large ketches on the south coast and across to France.
