hull"body of a ship," 1571, perhaps from hull (1) on fancied resemblance of ship keels to open peapods (cf. L. carina "keel of a ship," originally "shell of a nut;" Gk. phaselus "light passenger ship, yacht," lit. "bean pod;" Fr. coque "hull of a ship, shell of a walnut or egg"). Alternative etymology is
from M.E. hoole "ship's keel" (c.1440), from the same source as hold (n.).
