有桅的

I am told this is the greatest seaport in the world, with 650 miles of waterfront, and ships calling here from many exotic lands, but the only boat I've happened to notice since my arrival was a small sloop tacking out of the East River night before last on the ebb tide when I was walking across the Brooklyn Bridge.

我被告知这是世界上最大的海港，有着650英里的近水码头，有很多来自世界各地异国情调的船只到访，但是自我到来后我只偶然注意到其中一艘，当时我正步行穿过布鲁克林大桥，那是一艘小单桅帆船，正抢风航行在夜色中的东河上，要在退潮之前继续它的航程。

Aint Croix was a sparse and bare island where was the central seat of triangle trade zone with an unnoticed harbor providing an awesome shelter for the going and coming pirates' goods-loaded vessels. In January 1717, British soldier defeated the buccaneers and the survivors of the war was near the margin of death and was saved by the two sloops fleeing to Virgin Gorda.

t、 Croix在海盗的黄金时期还只是一个荒无人烟的小岛，由于处于三角贸易区的中心位置，又有一个不为众人所知的隐蔽的港口，所以为过往的海盗提供了非常完美的隐蔽场所。1717年1月，英国的士兵在此击败了海盗约翰，战争的幸存者在这里几乎被饿死，恰巧另外两个海盗单桅船救了他们并一起逃往了Virgin Gorda。

St. Croix During the Golden Age of Piracy, St. Croix was an unclaimed, largely abandoned island with a protected harbor and a good position on the Triangular Trade—perfect for a passing pirate hideout.
