We took the 2:45 Tuesday last year and this year, and it happened both times. It is strange as it is, to us, not security at all, just get off the ferry while we move it to the departure dock, then back on. Only one custom's agent, and no real check's. Don't know. I'm glad that for the last two time's our last night has been, against our will and desire's, on St. Thomas because of weird ferry activity. Sigh!
