   A large goblet or drinking glass, -- used for lager beer or
   ale. [U.S.]

Schooner \Schoon"er\, n. [See the Note below. Cf. {Shun}.]
   (Naut.)
   Originally, a small, sharp-built vessel, with two masts and
   fore-and-aft rig. Sometimes it carried square topsails on one
   or both masts and was called a {topsail schooner}. About
   1840, longer vessels with three masts, fore-and-aft rigged,
   came into use, and since that time vessels with four masts
   and even with six masts, so rigged, are built. Schooners with
   more than two masts are designated three-masted schooners,
   four-masted schooners, etc. See Illustration in Appendix.
