Show HN: Is Hormuz open yet?

• ananandreas 6mo ago
  May be possible to improve the delay by reviewing ship geolocation data. Those are open to public and there is probably many apis for it

• fraywing 6mo ago
  Very cool, thanks for sharing! What's the threshold function? Do you have graduating `No --> Partially --> Mostly --> Open`? Also what's the update cadence?
  • anonfunction 6mo ago
    So if it's under 25% of the prior year's crossing it goes to NO, otherwise it's counted as open. The update cadence kinda sucks because I didn't spring for the $200 a month live ship tracking data, so I'm using https://portwatch.imf.org/pages/cb5856222a5b4105adc6ee7e880a1730 https://portwatch.imf.org/pages/cb5856222a5b4105adc6ee7e880a... which lags by 4 days which isn't great for a site like this, but was fine for me on a little side project. Open to other data sources or ideas, of if anyone wants to sponsor an API key (I did reach out to a few vendors already if they would give the project api key in exchange for a link to their site). The original idea was to track ships and see how many crossed the strait but as mentioned above I didn't find any free sources so I went with what I did.
• truelson 6mo ago
  Really liked this. Made me laugh even if not intentionally funny. Also, given how markets and news cycles are moved with words not actions these days, I really like this site. There are still so many misaligned interests; this is a much tougher situation that may get some local stability for a period, but will likely return to chaos again.

  You might want to rethink scraping marinetraffic before you get a call from their lawyers? https://www.marinetraffic.com/en/p/terms https://www.marinetraffic.com/en/p/terms
  • anonfunction 6mo ago
    Fair enough, I'm actually not scraping it on any automated cycle currently, I just manually copied the JSON from their site to get some ships on the map. There's a few live ship tracking APIs I considered but they are expensive or their free offering just straight up didn't work. I sent a few an email if they would consider sponsoring the project, no replies yet. - AISStream.io — https://aisstream.io — Down/not working - DataDocked — https://datadocked.com — Ran out of credits on a single failed request - VesselFinder — https://www.vesselfinder.com/realtime-ais-data — Enterprise contact form, asked if they wanted to sponsor in exchange for a link - MarineTraffic — https://www.marinetraffic.com, their API is like an enterprise contact form, same as above, waiting for response.

• bl4ckneon 6mo ago
  Very cool! I love one off intresting sites like this. Thanks for building it and talking a little bit about where the data comes from etc. On the note of Ai agent getting the data for you, could you not just build a chrome extention that intercepts/read the api response and then uploads it to whatever ingest endpoint you have? You could probably just call their api end points they use on the page as well but not sure what protections they have so might be a bit tricky. A custom chrome extention could do it though if they have protections.
  • anonfunction 6mo ago
    Their APIs are protected by cloudflare, I didn't want to circumvent that. Also I dont really want to make a chrome extension or have a browster tab open, if that's what you meant? I've already made a cron style agent framework[1] so that's what I'd probably reach for since they can actually open the browser and inspect the network traffic to grab the json. 1. https://botctl.dev/ https://botctl.dev/

        I think I was just spit-balling what would be possible, rather than what I intend to do. As mentioned elsewhere I'm hoping to get an API key from one the data providers, I even reached out to the api behind marinetraffic.com, https://www.kpler.com/product/maritime/data-services https://www.kpler.com/product/maritime/data-services to see if they would sponsor the project. This was just something I built on a whim, but I appreciate your comment and took it to heart!
• ggm 6mo ago
  Maps can be so misleading. It looks like a dredging operation in Omani waters could alleviate this, if we'd started decades ago. Moving to a topographic view, it becomes clear the neck of land at "two seas view" is narrow, but tall. It would literally be moving a mountain. Panamax and suezmax boats are smaller than ULCC supertankers. Ferdinand De Lesseps time has passed. This would be ruinously expensive. Better to negotiate with rational intent.
  • dylan604 6mo ago
    > This would be ruinously expensive. I bet it could have been done with the money spent on the "war"
    • ggm 6mo ago
      Yes, but in circumstances where no war is in the offing, digging a giant hole next to 50km of open water begs questions. It would be impossible to get "it's a hedge against the future" over the line. The same to a lesser extent applies to pipes. You could construct pipes for gas, for some of the heavier oils and crude (what I read suggests pumping crude long distance is painful, it has to be down-mixed with lighter stuff to make it sufficiently fluid) but the fertilizer? that would mean converting dry to wet and back again (nobody ships fluid weight if they can avoid it) -Or ship the inputs: ammonia, and sulphur in some liquid form, and produce the dry goods on the other side. But, I think pipes have a stronger case than a canal: move the things which are amenable to pipes, into pipes, and bury the pipes. In times past, this would have been done as a convoy. China and other nations would have stepped to the fore, conducting safe passage with their own ships on the outside edge. But we're not in a world where this kind of thing works for anyone involved. Even offering to cover insurance risk doesn't look to have motivated ship owners to pass. (in times past, the US wouldn't have put itself or it's allies in this position, hence the reference to China) Don't be fooled by mental images of what a convoy looks like: ships like these maintain massive separation. There's almost suction between hulls moving at this scale, if they were within 500m of each other there'd be chaos if one had to take any evasive action. In reality (I believe) even a convoy consists of a a lot of discrete, clearly demarked and targetable things, not a large mass you can "hide" in. https://en.wikipedia.org/wiki/List_of_traffic_separation_schemes https://en.wikipedia.org/wiki/List_of_traffic_separation_sch...

• LAC-Tech 6mo ago
  It doesn't matter - Israel was able to ethnically cleanse and occupy large parts of Southern Lebanon, without undue Iranian interference. Mission accomplished for MIGA. The "Israel First" administration of the US will happily trade Iran's permanent control of an international waterway for the expansion of Israel.
• stavros 6mo ago
  I'm not really very up to speed on this, can someone explain how the strait is actually closed? Are the Iranians threatening to sink any ships that pass by, or what? How come any ships don't turn their transponders off and try to make a run for it?
  • MattDamonSpace 6mo ago
    They’ll sink ships or cause damage with low cost drones or missles The strait isn’t wide enough, Iran can see any ships attempting
    • stavros 6mo ago
      I see, thanks. Looks like the strait is 77 km wide, which isn't one ship's width but probably not wide enough that binoculars wouldn't see everything.
      • cwillu 6mo ago
        The navigable width where it is deep enough is significantly narrower.
        • stavros 6mo ago
          Good point, thanks.
  • luxuryballs 6mo ago
    From what I was reading Iran likely wouldn’t sink a civilian vessel but because the risk is there due to the threat they don’t do it because it would violate the contact for their maritime insurance, meaning even if you had a brave crew and orders to go, you lose all your insurance coverage against the loss if something goes wrong.
  • croisillon 6mo ago
    [flagged]
  • 6mo ago
• luxuryballs 6mo ago
  So apparently the reason they don’t just go for it is due to insurance. Because Iran technically isn’t suppose to just sink a civilian vessel, but the risk is there so the ships are ordered by the owner/stakeholder not to go due to the insurance coverage. Kind of interesting, they could technically call Iran’s bluff but it would mean, they violate the insurance contract and lose coverage? I’m just reading about this so probably not the full picture.
  • roncesvalles 6mo ago
    The capability is very real. And they don't have to sink the ship, just one Shahed drone exploding on the deck and injuring/killing a sailor is deterrence enough.
    • HiroProtagonist 6mo ago
      The Shahed drone is a 'set it and forget it' device where you program a stationary target and launch it. It would not work well for moving targets, like ships.
      • worik 6mo ago
        > The Shahed drone is a 'set it and forget it' device where you program a stationary target and launch it. It would not work well for moving targets, like ships. The Iranians are quite handy at modifying their drones....

        Russia has been modifying Shahed drones for quite a while. May be they've shared back or Iran got creative on their own
  • tokai 6mo ago

  I work for a consultancy that does vessel tracking as one of its main products, and yeah it's expensive! afaik they have remote teams with sensors at key points and a bunch of people using AI/software to manage things like GPS spoofing.

  This will be inherently inaccurate because data was based on public AIS signal, but ships are turning off their AIS to avoid detection. > In an attempt to evade detection, many ships appear to be deliberately switching off their tracking system - known as AIS (Automatic Identification System). https://www.bbc.com/news/articles/c4geg0eeyjeo https://www.bbc.com/news/articles/c4geg0eeyjeo

  • krisoft 6mo ago
    Everyone talks about the AIS signal being turned off in the strait as if it is an insurmountable problem. Ships had their AIS on before the war, and will turn it on again once they left the area. So we can just filter for ships which previously reported a location in the Persian Gulf, and now are reporting outside of it. Similarly we can count ships which were outside of the Gulf and now are inside. We don’t need the AIS to be on while they are transiting.

      Last year (March 18) Israel killed 174 children and 412 people in total in a day when violating a Jan 19 ceasefire to restart the genocide. Then proceeded to starve hundreds to death and severely compromise health of tens of thousands during the following months, while killing 1000s of aid seekers, that they forced into killing fields under starvation, like this: https://t.me/hamza20300/375017 https://t.me/hamza20300/375017 After this, they'll certainly not stop at bombing a few cities, or leveling villages today, that they can get away with because of western support.

  Iran (and various news sources) have claimed that the straights are not now, and in fact never have been, closed - provided the relevant ship was not involved/linked to the attacks on Iran, and that it coordinated with Iranian authorities. So, it could be that: * Iran is lying and that has not actually been an option. * A lot of the ships which would otherwise have transitioned are involved with the war somehow. * The relevant parties have decided not to coordinate transitions with Iran, for various reasons * The data displayed at the link is partial for some reason.
  • sethops1 6mo ago
    No need for baseless speculation, it's well known that no insurance company is willing to insure transit through the straight while it's an active war zone.
• spaghetdefects 6mo ago
  It was mentioned in this thread and quickly flagged, but Israel broke the ceasefire today by attacking civilians in Lebanon so Iran closed the straight. It was open prior to the ceasefire violation. France's Macron actually just commented on this: https://x.com/EmmanuelMacron/status/2041990505760772551 https://x.com/EmmanuelMacron/status/2041990505760772551

  • xdennis 6mo ago
    > Israel broke the ceasefire Correct me if I'm wrong, but Israel didn't sign any ceasefire. The ceasefire was between Iran and US. Israel separately announced (not part of any deal) that it would stop attacking Iran. It honored that self-imposed limit. Israel attacked Lebanon (Iran's proxy).
    • LarsKrimi 6mo ago
      It's impossible to know right now. Some are saying Pakistan messed up by not specifying properly to both sides what would constitute a cease fire. And US (Israel's proxy) is probably a bit unreliable in how their military command and political leadership separately interpreted the agreements as well /S trying to highlight how stupid it sounds when you try to retrofit sense into this conflict

VIIRS is very low resolution but you can make out vessels with reasonable accuracy in the night-time images. VIIRS covers most locations at least once per day, but the other sensors capture a given location only once per 5-10 days (although when combined, Sentinel-1/Sentinel-2/Landsat should provide close-to-daily coverage).

  According to the Financial Times (1), the straight is "open" but Iran is extorting fees for passing ships. > "Iran will demand that shipping companies pay tolls in cryptocurrency for oil tankers passing through the Strait of Hormuz, as it seeks to retain control over passage through the key waterway during the two-week ceasefire." If they really will start doing so for all shipping, that would be odd since the straight itself is in Oman's territorial waters. Even so, the UNCLOS convention (2) requires free transit: > Article 44 > Duties of States bordering straits > > States bordering straits shall not hamper transit passage and shall give appropriate publicity to any danger to navigation or overflight within or over the strait of which they have knowledge. There shall be no suspension of transit passage. It would be unprecedented and unlawful, but I guess previous actions of Israel, the US and Iran have shown our world is beyond adhering to laws and agreements now.

        Trump and the US effectively control the commerce because they are the only source of insurance. Even with payments and promises from Iran, no ship is sailing without insurance coverage. There is no one insuring the ships other than the US program Trump created.

      Well, it would be if everyone betting wouldn't have an influence on the outcome. That's "wisdom of the crowds". But what if the people putting money on the Strait being closed are the same that close them? Surely, that's no longer the wisdom of the crowds at play. Just perverse incentives.
      • FrustratedMonky 6mo ago
        I agree. Maybe an un-expected outcome. Who could have foreseen that a government/person would actually blatantly start a war, and manipulate bombing raids in order to manipulate a market, without being charged with a crime himself. In sports betting, it seems obvious if a player throws a game. In a war? Surely nobody would do this, right? Who could imagine it.
        • tomtomtom777 6mo ago
          You don't have to imagine some giant conspiracy. Fact is, that everyone can make a bet, and there are a lot of people with knowledge and influence in the political decisions made.

  Hello OP, I think using an ai agent to fetch the JSON is a bit of an overkill Here is a node.js script for you which will fetch the data and save it to the file: import fs from 'fs' import puppeteer from 'puppeteer-extra' import StealthPlugin from 'puppeteer-extra-plugin-stealth' puppeteer.use(StealthPlugin()) const browser = await puppeteer.launch(); const page = await browser.newPage(); async function fetchCoords(x, y, z = 8, station = 0) { await page.goto(`https://www.marinetraffic.com/getData/get_data_json_4/z:${z}/X:${x}/Y:${y}/station:${station}`); const jsonRaw = await page.evaluate(() => document.body.innerText); const json = JSON.parse(jsonRaw) return json } const data8353 = await fetchCoords(83, 53) const data8453 = await fetchCoords(84, 53) const data8354 = await fetchCoords(83, 54) const data8454 = await fetchCoords(84, 54) const fullData = { ...data8353, ...data8453, ...data8354, ...data8454 } fs.writeFileSync('data.json', JSON.stringify(fullData, null, 2)) console.log('done!') process.exit(0) Just like this, no need to spend a cent on expensive APIs or tokens

    Take your upvote, love the old school hn spirit. Reminds me of when I was speaking at a conference back in the mid 2010's with a presentation titled "Join the dark side of APIs" or something akin to that, where I showed many of the newly popularized "single page apps (SPAs)" relied on undocumented and public APIs, often without any authorization. Immediately followed by a talk by a business type guy on API copyright or something or other.

    If I had to pick one thing I like about software devs as a group, it's this: you find a problem, you solve it, you share the solution.

    What is the AI agent doing in this interaction? This is a public API exposed to any browser...

  Obviously the situation has significantly improved since then, your website is given outdated information. https://www.vesselfinder.com/?p=OMKHS001 https://www.vesselfinder.com/?p=OMKHS001 (click on map, zoom out). At this moment ~18 ships transiting. Not sure what the normal capacity is, and I think it's probably a bit more than this ... but it's at least mostly open.

  4 day delay kinda kills the point of the map no?

  I don't understand why ships can't just run on Oman's side of the strait, isn't there a dash-line down the middle for territorial waters integrity?

    Because it's only a few extra kilometres, Iran could still hit them.

  That's really cool. I tried to blog about it in the early days of the war and tried to show it in realtime as well. As you discovered, it's really expensive to get ship tracking APIs. So I also did something similar, where I took the JSON from Marine Traffic and mapped it onto a Mapbox map. I did a very rudimentary-ish job — I think what you created is much more refined.

  Very cool! Thanks for sharing. There is also this one- https://hormuzstraitmonitor.com/ https://hormuzstraitmonitor.com/

    This is very cool, I just wonder where they get the crossing data!
    • gagzilla 6mo ago
      I'm guessing from the AIS Vessel Tracking (mentioned in their data sources)- https://www.vesselfinder.com/realtime-ais-data https://www.vesselfinder.com/realtime-ais-data

  I like how this already includes the Polymarket estimate. Maybe there should be another category "new accounts on Polymarket that bet some suspiciously high amounts on those specific dates"...

• insane_dreamer 6mo ago
  This site has a lot of detailed data -- not sure what their sources are: https://insights.windward.ai https://insights.windward.ai Number of ship crossings is definitely trending upward as of today.

  I speculated over a month ago that the only way to get the oil flowing again is to build a trucking road thru the desert. Ask China to help in exchange for cheap oil. If they start now, they could have a rough path by end of the month. Once the road is built, then you lay new pipeline. Say 3-4 years to do everything. Once Hormuz is bypassed, Iran has lost all leverage.

  preditction market section is a great touch, OP
