In a metal lifeboat, which component is described as a heavy, rectangular metal bar?

The heavy, rectangular metal bar described is the keel. It runs along the bottom of the lifeboat and acts as the backbone of the hull, adding mass low in the boat to improve stability and help it track through waves. This fixed, structural element is built to resist bending and to anchor the rest of the boat’s frames, unlike the rudder (steering blade), the hull (the main body), or the deck (the top surface).
