need info on sailing Puerto Rico

[cruisergirl]

Hey there! I'm in the BVI's with my boyfriend on our (newly acquired) privilege 39' sailing catamaran (weehoo!). We are going to make our way to Florida for a partial refit before setting off for a global circumnavigation. We plan to make several stops before florida for fun and to start small with the passages. I would like advice from anyone who has recently cruised this area about visiting puerto rico. Specifically, the spanish virgin islands and Vieques. Wondering about anchorages.... visiting the bio bay... and if there's anything special we need to know about the customs/immigration process. (we are American on a US flagged vessel) We have an old cruising guide onboard our boat, and will be looking for another, but I thought I'd check here as well! Thanks in advance for any tips!!!
