Ich habe im Netz folgendes gefunden, daß ich auch schon im Thread zur Reiseproblematik gepostet habe. Ein paar exemplarische Reisezeiten aus der Antike. Unter anderem Tarraco - Ostia.

4.4 Travelling Time
In the summer the common mediterranean winds usually come from the north, speeding up the journeys of ships going to the south. Ships going to the north had to travel twice as long. Some usual sailing times are listed below:
Alexandria - Puteoli 15-20 days
Ostia - Carthago 3- 5 days
Gades - Ostia 9 days
Tarraco - Ostia 6 days
Narbo Martius - Ostia 3 days
For a distance along the coast of about 50 kilometres a small ship, with favourable winds and currents, would need about eight to ten hours. A land caravan consisting of beasts of burden would need at least two days.
4.5 The Shipping Season
The best sailing season was from May 27th to September 14th. March 10th to May 27th, and September 14th to November 10th were also considered reasonable periods. In the winter shipping came to an almost complete standstill. This period was called the mare clausum ("closed sea"). In this season the force of the gales was too great, and bad visibility at sea hampered navigation. Shipwreck or jettison were almost inevitable.
