How were Viking ships waterproof?

Answered by Jeremy Urbaniak

Well, let me tell you about Viking ships and how they were made waterproof. It’s quite fascinating, really. The Vikings were skilled shipbuilders and they had a clever way of ensuring their ships didn’t leak.

First of all, the ships themselves were all built in the same long, narrow shape. This design allowed them to be both swift and maneuverable in the water. The shallow draught of the ships meant that they could navigate in shallow waters, which was essential for Viking raids and exploration.

To make the ships watertight, the Vikings used a combination of materials. The spaces between the wooden planks of the ship were filled with various substances such as wool, moss, or animal hair. These materials acted as a sort of caulking, filling in any gaps and preventing water from seeping through.

But that’s not all. To further ensure the ships were waterproof, the Vikings mixed these natural fibers with tar or tallow. Tar, which was derived from pine trees, was heated and applied to the seams of the ship. It acted as a sealant, making the ship even more resistant to water penetration.

The use of tallow, a fat derived from animals, also helped in waterproofing the ships. It was heated until it became a liquid and then applied to the seams. Similar to tar, tallow worked to seal any gaps and provide an additional layer of protection against water.

The combination of these materials and techniques made Viking ships remarkably watertight. This was crucial for their expeditions and raids, as they needed reliable vessels to carry their warriors across long distances and often treacherous waters.

Now, while I haven’t personally built a Viking ship or sailed in one, I’ve read extensively about their construction and have seen replicas in museums. It’s truly impressive how the Vikings were able to create such seaworthy vessels using the resources available to them.
