“Our entire maritime architecture is built on the naive hope that data is honest. It’s a costly delusion.” Erik Bethel and Ami Daniel (Fortune)
In 1965, Swedish seaman Benny Pettersson found himself riding out Typhoon Jane off the coast of Japan. The storm was severe enough that his ship had to leave the harbor and anchor offshore. Visibility was nearly nonexistent, and even radar couldn't reliably tell crews where neighboring ships were located.
When the storm finally passed, Pettersson realized that his vessel had drifted nearly a nautical mile. They had no reliable way of knowing where every other ship around them had drifted.
He started to think: what if ships could automatically tell one another exactly where they were? And who they are? The answer to those questions was the Automatic Identification System, better known as AIS.
Like so many innovations, the idea for AIS arrived years before the supporting technology was available.
Early satellite navigation was still developing. GPS was introduced to improve positioning accuracy, but there were technical setbacks, funding challenges, and even a period when development shifted in the direction of military applications.
Perhaps most importantly, Pettersson spent years investing in advocacy to keep his idea alive and build awareness around the world.
Ironically, private yacht owners embraced the idea more enthusiastically than commercial shipping companies. This new idea found its earliest champions among individuals willing to experiment (and invest) before large industries were convinced of the potential.
Following the September 11th attacks, governments around the world began paying much closer attention to maritime security.
Suddenly, knowing where ships were, and where they were from, and who was piloting them, became more than an operational convenience. It became an international priority.
In 2002, the International Maritime Organization required AIS under the International Convention for the Safety of Life at Sea, or SOLAS. The requirement applied to international voyages by ships of 300 gross tons or more and to all passenger vessels regardless of size.
Misaligned Maritime Incentives
AIS is deceptively simple. Ships equipped with onboard transponders automatically broadcast information about their identity, position, course, speed, and heading.
Originally intended for ship-to-ship awareness and communications with shore stations, satellite networks eventually expanded that visibility across much of the world's oceans.
According to The Nautical Institute, AIS stations are designed to operate autonomously, requiring little or no routine human interaction.
AIS caught on because everyone benefited from participating honestly. Ships avoided collisions, ports gained visibility, regulators had better situational awareness, and commercial operators coordinated traffic more efficiently.
Everyone’s incentives were aligned.
AIS was built on the spirit of cooperation. In fact, one of the clearest descriptions comes from the AIS documentation itself: "AIS offers essentially no security and relies on the cooperation of the participants and on the enforcement of its rules by law and on plausibility evaluation."
There is no encryption or authentication in AIS. While that benefit helped the standard to scale, it has now become a liability. AIS spoofing and rolling are rampant, especially in the riskiest parts of the world to navigate.
At the same time, we have to judge each technology against the world it was designed to operate in. AIS wasn't built as an intelligence platform, or to enforce sanctions, or to expose and monitor shadow fleets. It certainly wasn't expected to become a foundational data source for insurance markets, commodity traders, financial institutions, or global supply chain visibility platforms.
AIS was designed to help ships avoid colliding with one another. And it does that - as long as everyone plays along.
Given the challenges faced by maritime vessels today, AIS will likely become one input among many. Combining AIS with satellite imagery, radar, behavioral analysis, and cross-validation from independent sources will make navigation and vessel identification more complete. Unlike AIS, it isn’t going to be cheap, but that is the world we live in.
The future isn't about replacing AIS, it is about recognizing the role it fills within a broader intelligence ecosystem and bolstering it as needed.
