It was seen as "fast and well sailing", but required a large crew to handle its rigging.[10] While brigs could not sail into the wind as easily as fore-and-aft–rigged vessels such as schooners, a trait that is common to all square-rigged ships, a skilled brig captain could "manoeuvre it with ease and elegance; a brig could for instance turn around almost on the spot".[11] A brig's square-rig also had the advantage over a fore-and-aft–rigged vessel when travelling offshore, in the trade winds, where vessels sailed down wind for extended distances and where "the danger of a sudden jibe was the large schooner-captain's nightmare".[12] This trait later led to the evolution of the barquentine. The need for large crews in relation to their relatively small size led to the decline of the production of brigs. They were replaced in commercial traffic by gaffsail schooners (which needed fewer personnel) and steam boats (which did not have the windward performance problems of square rigged ships).[10]
