"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.

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.

Island hopping is a niche where electric flight might get started.
As I understand it, Hawaii had environmental concerns with ferries (requiring a review that was never completed), specifically whale/ship strikes and the risk of car-carrying ferries transporting invasive species between the islands. [1] I'm unsure if other islands would have similar concerns about cargo ships or not or if the environmental review would have been satisfactory if they'd just done it on time.
I'd expect ferries and/or small cargo ships to be an attractive option if allowed.
The super ferry was incredible. Being able to drive your car on a different island was such a game changer vs buying flights for the fam and then having to rent a car. I miss it!

It doesn't appear to be in normal operation, but it has been tested:
I actually think there's an argument to be made for this to be an alternative to typical cargo ship operations.
The challenge when moving goods via ocean vessel is that everything takes _a long_ time. Loading and unloading the vessel can take days. Transit is weeks. Unloading the vessel takes days.
You have 2 options now: air freight which is crazy expensive but gets it there in a few days max or ocean freight which is relatively cheap but might take weeks. If you can cut out vessel loading/unloading you save at least a week.
amdsn 1 days ago [-]
I find it hard to believe that you wouldn't lose any time you gain in loading/unloading to transit time inconsistency when you have to rely on wind. This is not even to mention the fact that these ships cannot make good use of big modern ports with cranes and the best logistical connections and that it would take 100+ of them with hundreds of crew to move as much as a single container ship can with 20 people. I could see them being useful in niche scenarios like cabotage within island/archipelago nations or shipping small loads on irregular schedules, but for anything else it is very hard to beat a container ship.
devonkim 1 days ago [-]
This is HN, we can use an analogy of TCP window size or UDP packet size in an underlying high latency medium and the receiver and sender have very high processing costs. So perhaps solving the unloading and loading logistics is also worth optimizing for like we did almost for free in computing space? But because we don't have ballpark numbers of each terribly well we're going to have some difficulties with a valid non abstract system design discussion.

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).
wongarsu 1 days ago [-]
It's DHL. If you want your package or pallet shipped to some island it might take a long while until a big container ship makes the next stop there. If it can stop there at all. For a package/freight company, the capability to run ships on your schedule to small harbors is valuable. And a catamaran could be a competitive alternative to other smaller container ships
What I don't understand is that they are talking about running it trans-Atlantic. Taking longer than a normal container ship, while taking less cargo. You save on fuel, but surely the crew costs must be eating up all those savings. And you're not really faster. Unless the plan is to go point-to-point between smaller harbors, making up any lost time by saving on cargo handling time

You might not need much crew for a vessel that small. Automation can take care of most of it, and with the right equipment the ship can basically sail itself. Then you just need a captain and maybe some maintenance crew to keep the automation running.

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

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.

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.

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.
marcosdumay 23 hours ago [-]
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.
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.
