So 10K ton is the deadweight tonnage, not the capacity. According to[0] (a better source?) this little fella has a capacity of 700 TEU. The largest ships in the world (MSC Irina, MSC Loreto) have a TEU of 24,346, the largest COSCO ships are 21,413. New Panamax are 10,000-14,500 TEU.

"Container ships under 3,000 TEU are typically called feeders. In some areas of the world, they might be outfitted with cargo cranes."[1]
