I would be cautious about the twisting loads on containers. The side forces will be huge, especially in a swell. Then add mechanical parts that must work in an incredibly hostile environment, and lastly, add on the north Atlantic in the winter, and you are in for a bad time. Ships losing containers due to stacks collapsing happens very frequently, without any extra forces.

Look at a purpose-built sailship from the age of sail in a north Atlantic storm. It is a rough ride.

Another attempt in a similar fashion is the Oceanbird concept by Wallenius Wilhelmsen, but that means building the vessel from the ground to handle the forces and that over-head loading and unloading is not possible, thus the aim at RO-RO ships.

Personally, as a commercial sailor and software engineer, this container approach screams of VCs throwing money at commercial shipping without understanding the industry. Profit margins are non-existent and are already hugely optimized with possibilities for specialized solutions. This wing sail will have to compete with synthetic fuels without increasing the cost due to crewing requirements.
