Do you guys know if there are boat slips that you can buy? Maybe in South County? Is it worth it? The in laws have a house down there and I would like to have unlimited acess to my boat.

You can rent them, but very hard to come by. Like everything else in RI.........you gotta know somebody;)

Some places have "condo" slips, but I don't know of any in south county. If you really want to own a slip you have to buy the land under or next to water and build a dock on it.
