You are correct. The only regularly scheduled ferries in Puerto Rico are to the Vieques, Culebra, and the Dominican Republic. Once every two weeks there's a ferry to STT.
I read in the local news though that the company who just took over the PR/DR ferries is considering a service to the French Islands as well. That'd be nice... road trip to St. Barths!
