Honing navigation/ boat safety & handling theory wouldn't hurt if sailing is a relatively new recreation
www.navathome.com/I have completed the coastal skipper and found it worth while, Especially if you want to think about extended cruising. I just need a boat now to put it all in practice Lol.
Find some paper and/ or electronic charts to start looking where you want to go.
Then you could find an east coast cruising guide. There are a few out there, others could tell you what are good ones.
