Dunnage

Pieces of wood placed against the sides and bottom of the hold of a vessel, to preserve the cargo from the effect of leakage, according to its nature and quality. Abb. Shipp. 227, There is considerable resemblance between dunnage and ballast. The latter is used tor trimming the ship, and bringing it down to a draft of water proper and safe for sailing. Dunnage is placed under the cargo to keep itfrom being wetted by water getting into the bold, or between the different parcels to keep them from bruising and injuring each other.
