Strictly construed, the Jones Act refers only to Section 27 of the Merchant Marine Act of 1920, (; 19 CFR 4.80 and 4.80(b)), which has come to bear the name of its original sponsor, Sen. Wesley L. Jones. Another law that was enacted in 1886 requires essentially the same standards for the transport of passengers between U.S. points, directly or indirectly transported through foreign ports or foreign points (46 App. U.S.C. 289; 19 CFR 4.80(a)). However, since the mid-1980s, as part of a joint effort between the cruise ship industry that serves Puerto Rico and Puerto Rican politicians such as then Resident Commissioner, U.S. non-voting Representative Baltasar Corrada del Río, obtained a limited-exception since no U.S. cruise ships that were Jones Act-eligible were participating in said market.
