Raparie, A sheet is a rope, not a sail.

One rule of thumb is, A ship can carry a boat, but a boat can not carry a ship.
In the days of sail, a ship was "ship rigged" that is, three masts, square rigged. If rigged any other way, it is not a ship. It would be a Barque, schooner, brig or variations on those.

The name "schooner" comes from old Scottish word to schoon. A verb referring to moving fast over the water. And, of course, the schooner could sail circles around ships and sail much closer to the wind.
Donald McKay, a Scot, designed some of the fastest schooners ever built.The Cutty Sark was one of his most famous.
