If a ship makes long, slow rolls and takes time resuming a vertical position, it is referred to as crank, cranky, crank-sided, tender, or tender-sided.
If the ship snaps back to its vertical position when heeled, it is called ʻstiff.ʼ Stiffness refers to a ship's power to stand up to her canvas, and will offer great resistance to inclination from the upright, when under sail.
These weights will exert a downward force on the vertical centreline (imagining a line drawn through the centre of the ship and the metacentre is the point in the middle).
By looking at the various weights, distributions and contributing factors that may effect its buoyancy, remedies can be attempted to solve what has affected the ship's stability.
In the case of the Gresham Ship (1574), furring was the chosen method to solve its crankness.
