The Homer Marine Terminal barge basin is located on the northeast side of the Homer Spit approximately 0.5 miles (0.8 km) northwest of the Dudiak Fishing Lagoon, about 2 miles (3.2 km) southeast of Mariner Lagoon and 4 miles (6.5 km) southeast of Homer, Alaska.

The barge basin is a privately owned commercial facility for loading and offloading cargo. Barges and landing craft enter the basin and are allowed to go dry when the tide is out. The facility is also used for boat storage and large vessel moorage and haulout.

The barge basin is often used by Helenka B, formerly known as the Surfbird, a converted mine sweeper that was used by the U.S. Navy, receiving three Battle Stars for service in World War II, two during the Korean War, and eight during the Vietnam War. Following conversion to a landing craft, Helenka B is 176 feet (54 m) long with 3,248 square feet (302 sq m) of deck cargo space, and a reinforced dropdown bow gate for loading and unloading cargo which is 16 feet (4.8 m) wide by 16 feet (4.8 m) high. The vessel is used for delivering cargo to remote sites throughout Alaska where there are no or limited dock facilities. Read more here and here. Explore more of Homer Barge Basin here:
