Viking ships were marine vessels of particular designs used and built by the Vikings during the Viking Age. The boat-types were quite varied, depending on what the ship was intended for, but they were generally characterized as being slender and flexible boats, with symmetrical ends with true keel. They were clinker built, which is the overlapping of planks riveted together. Some might have had a dragon’s head or other circular object protruding from the bow and stern, for design, although this is only inferred from historical sources.

The San Felipe Launched in 1690, was one of the most beautiful Spanish ships of its era. She was led the Spanish Armada. San Felipe’s role in the war against the British and French was to help protect Spanish settlements and harbors but also to transport gold from the new world. The San Felipe was armed with 96 cannons enough firepower to match the best ships the French and British navies had to offer. In 1705, the San Felipe fought a heroic battle against 35 British ships but was captured by an English ship and badly damaged and ended up at the bottom of the ocean with several tons of gold.
