Another great option for Ferry Service between SXM and SBH is the ferry that leaves from Philipsburg. (Great Bay Express). They provide 3 round trips daily from Monday - Saturday and two round trips on Sunday. They leave SXM early morning, midmorning and late day. They use a larger ferry which improves the comfort of the trip over. They run specials also. I have included a link below to their website and a screen capture of their schedule.
