拖缆太松。

A tow rope as thick as a man's arm extended from several scantily clothed tow-men, all the way to the bow.

一根粗如人臂的缆绳，从几个衣不蔽体的拉纤人一直连系到船头。

A rope from the second vessel was secured around the shark's tail, but repeated efforts to tow the fish into the water failed.

第二艘船上的一根绳子系在鲨鱼的尾巴上，但多次将鱼拖进水里的努力都失败了。
