  • Oh wow, so they are only using sails?

    The article seemed a bit light on actually how it's been powered.

    My initial assumption was that it's just going to harvest wind out of the air to power electric turbines since there's probably so much wind at the sea so much of the time.

    But there's a quote in the article that says we're going with the wind, and not in a straight line.

  • An interesting comparison would be a standard cargo ship that goes as slow as possible.

    "Slow steaming" is already in use and has some dramatic impacts on fuel use.

    The limit seems to be "hotel loads" i.e. constant loads needed for crew, but the sailboat will have those as well and not spread over as much cargo.

    It's entirely possible that a sail boat that follows the wind might be higher carbon per cargo kg than a giant standard ship going very slowly directly to the port.

    Check of oil prices same day article was published:

    WTI $73.51/bbl BRENT $77.57/bbl MURBAN: $70.46/bbl

  • What we see in quotes is not the price of oil being shipped right now; it is usually a one-month futures contract. Traders expect that by this time, Hormuz will reopen. If it does not, they will lose money, but the actual price could be much higher.

  • I love this idea, but do these ships exist yet? I can only find renderings, and the company's "roadmap" page is not a roadmap (https://vela-transport.com/feuille-de-route/).

    The only real footage I can find is a construction video from a year ago: https://www.instagram.com/reel/DL9CSLdtkaP/

  • I dont know what I was expecting on the roadmap page after you said it was not a roadmap, but I did not expect to see a whale jumping over a human as part of the "roadmap"

  • The ships aren't new, but a large transport operator like DHL buying into the concept is.

    Well, unless you count pre-motor cargo ships of course, those were the only option for centuries.

  • What if we put a large wind turbine on a ship? A sort of modern set of sails if you will.

    A mid sized cargo ship has a 50_000Kw engine. A mid sized offshore wind turbine makes 1_000_000Kw. So depending on which way the wind is blowing it could work. Put a diesel electric drive and a full sized engine then use the wind turbine to see how much it could reduce fuel use. I was even having fun dreaming about the incidentals. how hard it would be to build a folding/quick assembly mechanism for the turbine to make harbor/bridge/crane access problems go away. could we duel purpose the wind turbine boom as a crane boom. Would a vertical turbine make sense?

    While reading up on wind turbines I ran across the depressing story of the small ferry Hornblower Hybrid. A lot of hype on how environmentally friendly it was in 2008 when it was retrofitted with two vertical turbines. But my first though was "those turbines look awful small" and they are, the best they could do is power the lights not the boat itself. The boat itself was retro fitted in 2024 and lost it's electric drive. https://en.wikipedia.org/wiki/Hornblower_Hybrid

    I bet even if it would work from an energy point of view, the extra complexity of the system would make it more expensive than a straight diesel ship from an operations and maintenance point of view.

  • There are several designs of kite propelled ships. Some commercially available.

    A generator and a propeller would only add weight and complexity for a loss in efficiency.

    There have also been ships with vertical turbines mechanically coupled to propellers. But you can't build them very tall, so you lose the best winds. Those haven't been good enough in the past.

  • It's difficult to see how huge these are from the photo in the wsj article.

  • Someone should make a sport out of this.

    We already have sailing sports where people race all kinds of wind-powered vessels, and they push the envelope of tech development, just like F1 and the car industry.

    Also rich people love this sort of thing. Give them something to do with all that money that has some sort of chance of improving things.

  • The startup building and operating the boats was founded by a famous yacht racer

  • In the big picture I am again and again fascinated by this. One of the oldest commercial services out there (post / shipping) proves repeatedly to be very innovative and strong in realization of new stuff like this. They were the first or one of the first, who deployed electrical cargo vans. https://de.wikipedia.org/wiki/Streetscooter

    To be accurate, they bought the startup. But still: they didn't wait for the automotive company to come up with a e cargo van.

  • Let's see it last. It won't. This is just a short-term private endeavor/vanity-press project. Just because a business uses a "sustainable technology" does not make it a sustainable business. Comparing cargo ships to airplanes is apples vs. oranges and reveals the author's deliberate "headline" motivation and lack of technology understanding compared to the actual ground truth of shipping.

    Until fuel prices change for the long-term and/or emissions regulations have an order of magnitude uptick as well as covering far more than sulfur (see IMO 2020 https://en.wikipedia.org/wiki/MARPOL_73/78#IMO_2020 ), there will be zero economic incentive to use wind-power over diesel/bunker-fuel power.

    And no, any advantages of docking at smaller ports are defeated by those ports having less land-transit access and we already have fleets of (smaller) cargo vessels serving these ports at insanely low $/ton/mile rates.

    Just like farms, all of the economics point to larger vessels, larger ports, and operating entity consolidation. See "The Box" by Marc Levinson https://a.co/d/0gtBkWwt or watch a few "What's Going On With Shipping" https://www.youtube.com/@wgowshipping videos.

    It will take some sort of global political or environmental catastrophic externality to even budge, let alone change, the status quo.

  • That sounds so familiar. I swear I once read the same comment about renewable energy generation. :)

  • At the risk of sounding overly negative, these things are pretty much always vanity projects. Someone wanted a really cool boat and managed to get some investors onboard. It’s more about an aesthetic than a business case.

    We’re talking here about a fairly large crew that will transport a small amount of cargo while taking a really long time. On top of that, these aren’t container ship so loading/unloading will take a long time. There is no economic case here.

    The only way you can make this somewhat work is by selling the aesthetic/story. E.g.: this coffee was shipped by sailboat. But even then, notice how every company linked in the article of another commenter aren’t actually operating anymore…

  • Is it powered by a windmill from a miniature golf course going out of business? I know some guys who built one like that once, but it sank on its maiden voyage.
    by pseudohadamard
  • "415 metric tons of goods. That means they have about five times more cargo space than an airplane, but are five times smaller in length than a typical container ship."

    Not to take anything away from this (it's great), but for reference, an average vessel in Maersk's fleet can carry about 100,000 metric tons so you'd need about 250 of these to replace a single container ship.

    Not sure why the article decided to compare cargo capacity of a airplane with the length of a container ship, but alas.

  • the way the american administration is pushing for de-globalization... this might be the perfect future market.
    by senectus1
  • Urm, it's pretty well documented that historically the biggest deciding factor in shipping is cost. The size of the vessel and the travel speed are unimportant vs cost of the journey. So if they can essentially remove fuel cost, they're able to reduce the shipping cost and hence outcompete bigger vessels on the only metric that had historically mattered in that industry

  • > Not sure why the article decided to compare cargo capacity of a airplane with the length of a container ship, but alas.

    Because journalism is plagued by innumeracy. Same reason the author is talking about the length of cargo ships instead of the volume.

    by rayiner
  • The important metric should be emissions per metric ton though, including construction of the ships.
    by pier25
  • This was my exact intuition. At 450 metric ton, we're three orders of magnitude away from what large container ships can do. It's a nice PoC but this is clearly just PR from DHL.

    Air freight is also an odd comparison since it's usually time-sensitive and/or pricey ($100+ per pound).

  • This might be useful for a tiny island. Ship from a large Caribbean island to a small one for example. The distance means the round trip is day (night?) trip, and there a things you want shipped in every day, but airplanes are expensive. I'm sure there are other niches where there is only a small amount of cargo going from point A to point B as well. However in general the world needs more cargo and so this doesn't make sense for most.
