I have taken the ferry from Red Hook to St John. However I didn't get off - it goes on to the BVI. There was no rough water at all - did this the 1st part of Jan. several years ago. Most people of the ferry were geting off at St John - day trippers. The beaches looked fantastic as we ferried by the island.
If you take it to BVI, you stop & get off at St John for customs coming back to St Thomas. This doesn't take long - but be sure to have your passport with you.
