In this week’s newsletter, we talk to the head of the new USA Shipbuilding Coalition as the group launches an advertising campaign to take its message to the American people. We also explore a Pacific Carriers tanker movement that would have required the Jones Act before Trump’s waiver of the cabotage law, Washington’s position at the International Maritime Organization decarbonisation discussions and reports that two US-flag ships have been able to transit the Straight of Hormuz under Project Freedom.
