Is the Jones Act a modern Navigation Act?

Are the Navigation Acts comparable to the modern United States Jones Act?

The comparison rests on a shared rationale: protecting domestic shipping and encouraging investment in maritime infrastructure.

The Jones Act comparison concerns a shared rationale for protecting domestic maritime capacity. In the seventeenth-century English system, guaranteed routes encouraged investment in merchant ships and shipyards. Armed merchant vessels generated demand for cannon, while commercial crews expanded the pool of seafarers available to man the navy. Those civilian capabilities could make naval mobilization and construction less costly. The analogy concerns that industrial and strategic rationale, without equating the detailed rules of the two systems.
