We sailed on means literally “sailed around (something).” This same verb appears in 27.40 and is used there with anchors as its object. Puteoli, near Naples, was the regular seaport for ships coming to Rome from the east. However, since Puteoli was essentially a harbor, it may be useful to employ at this point “came to the harbor of Puteoli” or “came to the town of Puteoli which was a harbor.”
