Awesome idea. Would the potential savings in fuel not warrant this as part of a more permanent fixture onboard rather than from shipping containers?

(Assuming a fuel price of $550 per metric ton, the cost of fuel for a trip from China to USA would be around $1,485,000 (2,700 metric tons * $550))

We agree that a permanent installation would be awesome, but we came across some difficulties with that idea in customer conversations. First is the number of containers you permanently displace might mean you never recover your investment. Having a removable solution allows you to access the containers under the sail without any difficulty at the port. A permanent solution also requires time in a shipyard to install the foundations and mechanisms. There are thousands of ships out there which will need retrofits, and shipyards are already struggling with capacity, so a solution which you can build inland, then ship to and rapidly install at a dock makes sense to us.
