I would love to see a simulation of the forces involved here because I just can't see it adding up. A 60m tall sail introduces some really significant torque which may well be handled by the double container but how does that force get transferred from the sail to the container? The design requires a lot of moving parts and the reliability of the system appears to be safety critical. If the sail can't be reefed in high winds then it risks serious damage to the ship. And if it can't be reefed when entering port then you can't dock the ship. Until the technology has been proven to be extremely reliable I can't see any operator risking installing it.
