烏石港早期對外海運船隻，以戎克船與垵邊仔為主。船隻由烏石港進入宜蘭河時，因河道較淺，需將貨物自戎克船或垵邊仔卸下，改由舢舨類的河船（駁仔船與鴨母船）運輸至內陸。

Early maritime transport at Wushi Harbor primarily relied on Junks and An-pian-á. When vessels entered the Yilan River from Wushi Harbor, the shallower riverbed required cargo to be unloaded from Junks or An-pian-á vessels and transferred to sampan-style river boats for transport further inland.

烏石港航運鼎盛時期，「隨時入市，有船頭貨，動則星消」；進口貨物有來自江浙與福州的綢疋、羊皮、雜貨，漳州、泉州、惠安、廈門的乾果、麥、豆、瓷器、紙錢、藥材，廣東、澳門的雜色洋貨；回臺空船多載石材以壓重，即「壓艙石」。輸出貨品有稻米、麻苧、大菁、雜貨與樟腦。

During the heyday of Wushi Harbor’s shipping era, it was said that “goods entered the market at all hours; once the shipments arrived, they were sold instantly”. Imports included silk fabrics, sheepskins, and sundries from Jiangsu, Zhejiang, and Fuzhou; dried fruits, wheat, beans, ceramics, joss paper, and medicinal herbs from Zhangzhou, Quanzhou, Hu’an, and Xiamen; and miscellaneous Western goods from Guangdong and Macau. Returning empty vessels often carried stones as ballast, known as “ballast stones” (yachangshi). Exported goods consisted of rice, ramie, assam indigo, sundries, and camphor.
