This is a large sailing vessel that carries all vehicles that have wheels and can be driven or towed. It is like a large sailing parking lot. The vehicles are stored below deck and are not open to the elements. This is the chosen method manufacturers use to transport new vehicles. For a vehicle to be transported in a RoRo vessel, it must be able to drive or roll, steer and brake. There is an additional charge if the vehicle rolls, steers and brakes but does not drive. A vehicle such as a trailer can also be sent RoRo if it can be towed.
