Very easily 100% could and is be made in the USA. Higher quality and not using what amounts to slave like labor. However if I remember correctly only a total 70 to 80 percent of the vessels needs to be built and/or made in the USA. These rules and laws vary in requirements from type vessel to type of vessel and project to project The Pride of America project was a small special program which was a confusing debacle from the start and got more confusing and more of a debacle as time went on.
You will also find many of the leading maritime nations of the world also have laws similar to the Jones act that protect their own nations vessels. Canada and Britain comes to mind right off.
Right now there are very few if any US vessels in lay up should the nation require them and those that are there, are 50 + years old, making them generally useless. If there isa national emergency we will have big transportation/supply issues.
The Jones act and related laws are designed to protect the American Merchant Marine and keep US flag commercial vessel around and available in case of national emergency's and war. Without them you could easily find only crews from some 3rd world countries, with minimum training running tugs and barges, vessels not only port to port along the US coast or inland, up rivers and in harbors. Yes some vessel are now running along the coast, but at least they are not operating independently inland.
US commercial yards are among the finest in the world , however foreign countries spend one heck of a lot more to subsidize the labor, yards and underwrite the bank loans, which make it very hard for Us yards to complete.
As long as US industry is competing unfairly on a uneven field, is very hard to match subsidized industries, labor and products from foreign sources. So the next time you buy foreign products, think that the job that maybe lost maybe be your own, down the line.
