American Heritage® Dictionary of the English Language, Fourth Edition
- n. One of a pair of movable boards or plates attached to the hull of a sailing vessel to reduce downwind drift.
Century Dictionary and Cyclopedia
- n. One of two long flat pieces of wood attached one on each side of a flat-bottomed vessel (as a Dutch galiot) by a bolt on which it traverses. When the vessel is closehauled the board on the lee side is let down, reaching below the keel, and when the ship is listed over by the wind it resists the tendency to drift too fast to leeward.
GNU Webster's 1913
- n. A board, or frame of planks, lowered over the side of a vessel to lessen her leeway when closehauled, by giving her greater draught.
