       | Well, that's a bummer. That said, this does seem the way of the
       | future. We just need to either figure out maintenance robots
       | and/or find a way to keep human crew happy on long, slow voyages
       | across the Pacific.

         | those are inflatable as well.

         | the economies worked out.

         | The few people I know who pursued jobs on boats did so because

         | Combine that with the modern availability of high speed
         | internet via Starlink and entertainment is not a problem.

         | You've got to be kidding. Using a fully sail powered cargo

         | motorized cargo vessels will probably use some form of sails to
         | slightly reduce fuel burn on downwind legs but it's physically
         | impossible to move huge volumes of cargo purely by sail power
         | in an economical way. There just isn't enough energy in the
         | wind.

       | I love that they're trying this. It appears the more practical
       | goal might be retrofitting existing vessels with large sails to
       | augment the motors, but making a point with a fully wind-powered
       | vessel is a good show. Well, it would have been fully wind
       | powered if not for the damaged sail. Good on them for sticking
       | with the journey, though. I hope they keep running the vessel and
       | get a few more fully wind powered journeys.

         | I _think_ the notion was to fit masts to existing container
         | ship and stacks, and I gsve it scant attention as my intuition
         | (I once studied actual civil /mech engineering prior to jumping
         | ship for applied math) suggested masts are better as integral
         | parts of ships rather than bolt on after thoughts.

         | I'm Joseph, and along with Arpan and Bailey we are the founders
         | of OutSail Shipping. We're building a sail the size of a 747
         | that rolls up into a shipping container.

         | When deployed, it will generate thrust from the wind to reduce
         | the fuel consumption of a cargo ship. An array of these devices
         | will reduce fuel consumption on ships by up to 20%. These sails
         | are easily stowed and removed to cause no interference with
         | cargo operations.            Here's a short video showing our
         | prototype:

         | Not quite as I remembered .. kite sails, et al. are a good
         | idea, I'm still a bit torn by the physics of a container
         | deployed boom extension sail and the thrust transmission to the
         | ship. Still, I haven't modeled it, so take my thoughts with a
         | grain of salt.
         | 
         | EDIT2: Both links appear dead, so I guess that was a swing and
         | a miss. Still, good to see such ideas pursued.

           | given the long life of ships, there is much more interest in
           | retrofit than in new build.
           | 
           | You mention container ships. I haven't seen anything explicit
           | on these, and I think the reason is probably that they cruise
           | much faster than bulkers and tankers, which means the
           | potential savings from sail is smaller. I would have thought
           | 20% optimistic even for a new-build.

             | for ships can struggle in severe weather to keep the boxes

             | bad weather.
             | 
             | Your point is well taken, I might suggest that container
             | ships could be segregated into fast and slow cargo and that
             | might help somewhat with total fleet fuel consumption.
