From ISBE: Plank, plank: Thick beams or pieces of wood, for which several Hebrew words are used. The Revised Version (British and American) changes "planks" (of fir) into "boards" in 1 Kings 6:15, and in a few instances substitutes "planks" where the King James Version has "boards" (Exodus 27:8; Exodus 38:7, the altar; Ezekiel 27:5). So in the New Testament in Acts 27:44, for sanis.
