Chapter 2. This paper is about boats, but it is about boats as transportation, about the integration of boats into production on a daily basis, about boats being used to haul material 100 meters across a lake or 1000 kilometers over difficult seas. It is not about the evolution of boats or about evidence for the earliest boats, or about boats as the only way to get to Australia, or as a means to people the Americas. It is about boats as instruments of production and whether the use of boats is theoretically important.
