RORO Boats

The roll-on, roll-off (RORO) boats were designed mainly to transport vehicles, big and small. They are a good and useful invention because they have facilitated the transportation of people and their goods over long distances. But since it was on the eve of the Holy Week, vehicle and passenger volume was huge. Congestion was the natural consequence.

Congestion can be minimized if there are plenty of boats to carry people and vehicles anytime of the day.

Outside of peak travel seasons like Holy Week and Christmas vacations, I don't know if the same level of congestion can be observed.
