Petty Officer 2nd Class Austin Heath, a marine science technician from Coast Guard Sector Honolulu and a native of Chesterfield, Virginia, checks a firebox aboard the Galaxy Leader, a 620-foot roll-on/roll-off ship, during a vessel inspection in Honolulu, Sept. 23, 2019. Roll-on/roll-off ships - also commonly known as “ro-ros”- are designed to carry wheeled cargo that is driven on and off the boat, such as cars, trucks, semi-trailer trucks. The Sector Honolulu prevention team ensures that these vessels can operate safely in U.S. ports and waterways for the protection of mariners and the environment.
