The benefits of the concept are manifold:
The sailing part of the vessel does not need to obey to port-infrastructure restrictions concerning the rigging system, since this part will stay outside of the quayside. Moreover, the aerodynamic quality of the rigging system as well as its straightforward design, which are of importance for economic and robustness reasons, can be optimized without compromising on port-side related cargo handling aspects. Near the harbor, the system will disembark the cargo-holding part, which will move on into the harbor where the cargo is taken care of in a conventional manner.
Further benefits come along with the additional operational opportunities of this concept. The barges can be prepared in advance and will just be exchanged outside the port, which leads to short stops for the actual sailing vessel that operates in parallel to the harbour operations performed by the barges.
The variety of prevailing wind-systems on one cargo route, could require different wind-propulsion systems, depending on the course sailed towards the mean wind direction. By disconnecting the cargo from the wind-propulsion-system a rapid redistribution to other vessels, equipped with a different wind-propulsion systems, for maximizing wind-propulsion efficiency, is possible.
Depending on the size of the barges they can also directly be used for subsequent (inland)
waterway transportation to the final cargo destination, skipping the need for transshipment of the cargo in the seaports.
Such aspects will relieve seaport logistics, accelerate cargo handling, improve wind-propulsion efficiency and operating costs.
