# The Jones Act was supposed to build shipyards. It closed 300 instead.

The protection written into the Jones Act did not grow American shipbuilding. It collapsed the domestic fleet and shipyard base.

This law was written to build American ships and shipyards. It did the exact opposite.

Between 1983 and 2013, 300 domestic shipyards closed. Just four remained open. [^2] The large oceangoing Jones Act fleet fell from 257 vessels in 1980 to 96 by mid 2021. [^5] The United States now ranks nineteenth in commercial shipbuilding. It builds fewer than five ships per year. China builds more than 1700. [^3]

Building a tanker in the United States costs double the foreign yard price. [^4] Operating a Jones Act compliant vessel costs at least twice as much as an equivalent foreign ship. [^1] High costs killed demand for domestic ships. That shrank yards. That shrank the fleet. That is the result this protected market produced.
