2013年5月30日，三沙市甘泉岛和永兴岛之间船舶交通完成了首次试航。目前，三沙市岛屿之间交通主要依靠渔船和小型交通船，这些船只航行速度慢，安全保障不足。将来的甘泉岛船舶交通将缓解这一问题。
A traffic vessel between Ganquan Island and Yongxing Island in Sansha city finishes its first trial sail on May 30, 2013. The trial sail, mainly around the waters of the Qilianyu subgroup of Yongxing Island, was prepared for future inter-island traffic. Currently, traffic between islands in Sansha city relies on fishing boats and small traffic boats, which are slow and not secure enough. The future Ganquan Islands traffic vessel will relieve this problem. As China's youngest city, Sansha was officially set up in July last year on Yongxing Island in the South China Sea. The city administers three island groups - Xisha, Zhongsha and Nansha - and their surrounding waters in the South China Sea.
