- Lucas: So we've talked a lot about Srivijaya's trade networks—camphor, spices, beads—and about the Orang Laut as warriors. But there's something even more fundamental that made it all possible: the ships themselves. Luna: Right—you can't have a maritime empire without the boats. Lucas: Exactly. And Srivijaya's ships weren't just any boats. They were among the largest and most sophisticated ocean-going vessels of their time, built by skilled shipwrights in the riverine harbors of Palembang and along the Batang Hari. Lucas: These ships were known to Chinese writers as the K'un-lun Po—'K'un-lun' being a catch-all term for Southeast Asian peoples, and 'Po' meaning ship. Zhao Rugua, writing in the 13th century, described them as huge, seaworthy vessels that could carry several hundred men and vast cargoes. Luna: Was that the same as the 'jong' that we hear about later? Lucas: Great question. The term 'jong' appears later in Javanese and Malay sources, but it's likely that the K'un-lun Po were the predecessors—or early versions—of the jong. Both were large, sturdy, ocean-going ships built without iron nails, using a technique called lashed-lug construction. Lucas: Instead of nailing planks together, the shipwrights carved lugs—protrusions—into the planks, then lashed them tightly with vegetable fibers. The hull was built from the inside out, and the result was a flexible but incredibly strong vessel that could flex with the waves rather than crack. Luna: So it was like a wooden basket that moved with the sea. Lucas: Exactly. And they used tanja sails—those distinctive triangular sails that could be pivoted to catch wind from almost any direction. That gave them incredible maneuverability in the variable winds of the monsoon. Lucas: We have actual archaeological evidence for this. The Belitung wreck, discovered off the coast of Belitung island in 1998, was an Arab dhow that sank around 830 CE. It carried Chinese ceramics, but the ship itself was probably built in the Middle East. However, the Intan wreck—found in the Musi River estuary—was a Southeast Asian ship, dating to about 1000 CE, that used lashed-lug construction and carried a mix of local and Chinese goods. Luna: So the Intan wreck might actually be a Srivijayan ship? Lucas: Almost certainly. It was found in waters controlled by Srivijaya, and the construction techniques match what we know from Chinese descriptions. The cargo included iron, bronze, ceramics, and even resin—a typical Srivijayan trade mix. And the ship was about 20 meters long, which was large for the time. Lucas: But here's the thing: Srivijayan shipbuilding wasn't just about technology—it was about control. The Orang Laut, who were the maritime specialists, were also the shipbuilders. The maharajas controlled the forests that produced the teak and other hardwoods, and they controlled the shipyards. That meant they could build fleets that no rival could match. Luna: So the ships themselves were a tool of empire, like a navy but also the merchant fleet. Lucas: Exactly. The same ships that carried spices and camphor also carried envoys to China and pilgrims to India. And when the Chola king Rajendra Chola attacked in 1025, it was the Srivijayan fleet that fought back—though ultimately they lost. The Cholas probably captured or destroyed many of those ships. Lucas: After that, Srivijaya never fully recovered its maritime dominance. And by the time Melaka rose in the 15th century, the shipbuilding tradition had shifted to Java and the Malay Peninsula. The great K'un-lun Po were gone. Luna: It's strange to think that such advanced shipbuilding technology just disappeared. Lucas: Partly it's because the wood rots in the tropics. But also, the political structures that supported it—the Srivijayan mandala, the Orang Laut networks—collapsed. Later kingdoms built different kinds of ships. The jong tradition continued, but the specific Srivijayan design was lost. Lucas: You know, this kind of deep dive into the material side of history—what people actually built and sailed—is exactly what makes these episodes possible. And I'm always mindful that it's listener support that keeps us ad-free and able to spend time on these details. Luna: Yeah, it's a labor of love, but it does take resources to research and produce. Lucas: If you've gotten something out of these conversations—whether it's an hour of escape or a new way of seeing the past—a couple of dollars a month makes a real difference. Buy me a coffee dot com slash fexingo. No pressure, just if it's in your means. Luna: And it genuinely helps keep the research going. Now, back to the ships—what else do we know about how they were built? Lucas: There's a fascinating detail in the Undang-Undang Laut Melaka, the maritime code from the 15th century, which likely preserves earlier Srivijayan customs. It describes the roles of the nakhoda—the captain—and the kiwi, the navigator. The code specifies how to divide cargo space, how to handle disputes, and even how to deal with storms. Lucas: So we can reconstruct a lot about how these ships were run. For instance, the code says that if a ship is wrecked, the nakhoda is responsible for salvaging the cargo, but the crew shares in the loss. That suggests a kind of partnership model, not just a top-down hierarchy. Luna: So the crew had a stake in the voyage? Lucas: Exactly. They weren't just sailors—they were investors in a way. And that probably made them more motivated to protect the ship and cargo. It's a very different ethic from, say, European merchant ships of the same period. Lucas: One more thing: the ships were also cultural carriers. Yijing, the Chinese monk who studied in Srivijaya in the 7th century, traveled on a Srivijayan ship to India. He wrote about the comfort and safety of the voyage—the ships had multiple decks, cabins, and even spaces for worship. Luna: So there were Buddhist monks chanting on the decks as they sailed across the Indian Ocean. Lucas: Exactly. The ships were not just tools—they were floating monasteries, trading posts, and embassies all at once. And that's why Srivijaya's shipbuilding was so central to its identity. When the ships vanished, so did the empire. Luna: It's amazing how much we can piece together from wrecks and texts. Lucas: It is. And each new discovery—like the Belitung or Intan wrecks—gives us a little more. So next time you see a model of a jong or a tanja sail, you'll know it's part of a much bigger story.
