hog chains

A system of chains and rods meant to prevent wodden hulls from sagging, or "hogging," under heavy loads. The hull construction of the western steamboat tends to warp up in the middle and sag at the extremities; this hog chain system is the preventative. Hog chains extended from the forward hull, up over the hurricane deck, and back down to the stern. They could be tightened or loosened as needed by means of turnbuckles.
