All maritime and longshoreman occupations are prohibited for minors under eighteen years of age.
(A) "Maritime occupations" mean any employment on a ship, tug, barge, or other vessel; in the operation and repair of such vessels, and in the loading and unloading of such vessels. "Maritime occupations" are not necessarily a maritime service because it is rendered upon the high seas, a river, or other navigable water. To be a "maritime occupation", there must be a relation to commerce or navigation and a connection with a ship, tug, barge or other vessel employed in trade.
(B) "Longshoreman occupations" are those jobs where one works in the loading and unloading of ships, tugs, barges, or other vessels.
