What types of transport were used in the 9th-12th centuries to transport goods?

Basically, they tried to use sea transport, the goods were transported by shuttles, ships, sailing ships – this was a safer way of transportation, although there was not a big danger in the form of a storm, pirates. It was more problematic to deliver goods by land, firstly, it was much longer in time, and secondly, there was a danger of an attack by robbers, so the caravan needed increased protection.
