"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.
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.
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.
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.
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).
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
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.
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…
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.
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.
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"
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.
20 years ago I read this magazine article about putting kites on container ships for efficiency. This gadget seems to have durable appeal to entrepreneurs and/or suckers.
Incredibly efficient, but if they're burning hydrocarbons to move, at scale they are incredibly damaging to earth's atmosphere, and to animals disrupted by engine and propeller noise.
International trade is wonderful, all this new tech we're drowning in is amazing, and- understand that every one of us will eventually die, hopefully passing on some positive influence to others along the way, and that it turns out opting for the new car, the big climate-controlled house, the weekly/monthly/annual/still-too-frequent long-distance flights/drives, the new pocket computer every few years, the fancy unnecessarily-powerful laptop, the hours spent on all the man-child hobbies because we haven't outgrown our childhood insecurities, all this is an incredible waste compared to the meaning derived from healthy relationships with people within walking distance, tending the land we get our food from.

Or most research and technological development requires years or generations of experimentation and failure before success. And every time, the creators and innovators are told they are wasting their time, suckers, look how many failures came before you, ...
