Definition of lace piece in English:

lace piece

Pronunciation /ˈleɪs piːs/

noun

historical Shipbuilding
  • A piece of timber attached to the head of a ship in order to support the figurehead.

    The lace piece is a feature of changes in sailing ship design in the early 19th century, which meant that the figurehead could no longer be attached directly to the knee of the head as it had been formerly.

Origin

Early 19th century; earliest use found in William Burney (1762–1832). Apparently from lace + piece.
