Ship comparison
Compare ships across maritime history
Compare what different vessels were built to do, how they moved, and what kinds of waters and journeys they suited. The comparison avoids false precision where historical evidence does not support a single standard specification.
Why historical ship comparisons need context
A ship is a solution to a set of practical problems. A longship emphasizes speed, rowing and shallow-water access. A knarr gives up some of that shape in exchange for greater cargo capacity. A Polynesian voyaging canoe belongs to a different technological tradition and worked together with Pacific wayfinding knowledge. Treating those vessels as contestants in a single ranking removes the reasons they took the forms they did.
Historical evidence also differs by vessel. Some ship types survive as archaeological hulls or ship burials. Others are known through fragments, iconography, written descriptions, living traditions or later reconstructions. The comparison therefore focuses on strongly supported characteristics and identifies broad labels such as "dhow" and "junk" where a single fixed design would be misleading.
