Harbor-assist tugboats have a simple job: to “make fast,” or tie up to a ship, and guide it through the harbor without causing catastrophic damage to bridges, sailboats, or drunken party yachts (which are everywhere in Charleston). Although rare, accidents do happen. In 2019, the Golden Ray car carrier capsized off the coast of Georgia, resulting in more than $200 million in damage. The ship was carrying approximately 4,100 brand-new Kia and Hyundai vehicles. Still, maritime operations are usually a matter of accident-free ritual.
