What method did the Greeks use to get their boats from one side to the other?

The ancient Greeks often used a method called "transshipment" to get their boats across bodies of water. This involved unloading cargo and passengers from one vessel and transferring them to another vessel on the opposite side. In some instances, they also used small boats or rafts to ferry people and goods across narrow straits or rivers. Additionally, in specific locations, they might have employed a system of ropes or pulleys to pull boats overland.
