square-rigged

At the end of two hours they came upon a square-rigger with her decks just awash, and six men clinging to her rigging.

"Then keep your eye on the mizzen-royal," said the old man, as if he were forgetting that we weren't a square-rigger.

I thought perhaps you were trying to ring in a square-rigger on me, and I'm not familiar with them.

Hence a schooner is often called a "fore-and-after;" and a ship, a "square-rigger."
