"Wear ship" is a term commonly used in nautical language, which refers to the manoeuvre of turning a ship in order to bring the wind onto the opposite side of the vessel. This can be accomplished either by tacking or by gybing, depending on the direction of the wind. A synonym for "wear ship" would be "tack ship," which means to turn the vessel into the wind, thus changing its direction. Another synonym could be "gibing," which is a sailing manoeuvre used to turn a boat when the wind is behind it. Other than these, "altering course" and "changing direction" can also refer to "wear ship" in a broader sense.
