Now you are talking!!!
Like I have said many times, the only thing that stops you from reviving US Maritime industry and US Mariner jobs is the Jones Act as it stands today.
If it was modified to become only a Cabotage Law, i.e. regulate trade between US ports, but allowing any vessel under US flag MANNED BY US MARINERS ONLY to trade in US water, incl. the OCS, you could obtain what you have been advocating so strongly for fairly quickly.
This would entail removing the "US built" requirement, which is hollowed out anyhow.
It would also require the US Congress to ratify MLC 2006 and scrap the "offending" parts of the Jones Act that keep even US Owners from hiring US Mariners.
It would also enable US companies to renew and modernize their fleet at a very low cost, especially as top modern vessels are in the market at rock bottom prices at the moment. (It will not last much longer, however)
When that option dries up US Shipyard would be forced to compete for contracts at even terms with foreign yards, thus need to modernize, or go bust. (Cutting top management numbers and remuneration would be a first step)
As for US-flag vessels in foreign trade, they must be allowed to hire qualified foreign rating to stay competitive. US Officers doesn't cost any more than their European eqv.
Then maybe you could see VLCCs, VLNGCs, HLVs, Containers ships and even Cruise ships under US-flag, carrying at least their "fair share" of US export and import.
To try to "demand" that others pay more for the privilege of using US-flag ships and US mariners has not worked in the past, nor is it likely to work in the future, no matter how many Aircraft Carriers you put on the oceans.
