U.S. shipbuilding exports are tiny compared to exports of semis and trailers. Shipbuilding is subject to the protectionist Jones Act which hinders competition, while the semi industry is not.

Is the Jones Act truly the enemy in this situation? While it might limit some types of foreign competition, it enables, "seamen who have been injured at sea during the course of their employment to bring a personal injury action against their employers." See: www.law.cornell.edu/wex/jones…
