Our cargo ship lost three days after drifting into the doldrums near the equator.

我們的貨輪漂進赤道附近的無風帶，因此耽誤了三天。

The cruise brochure explains how early sailors survived weeks stuck in the doldrums.

這份郵輪手冊介紹了早期水手如何在無風帶受困數週後存活下來。

Please update the shipping schedule, since vessels crossing the doldrums often face delays.

請更新出貨時程，因為穿越赤道無風帶的船隻經常延誤。
