17. Which action reduces the yawing of a vessel in a following sea?

Shifting weights to the stern reduces yawing in a following sea by improving directional stability and rudder effectiveness; trimming by the stern keeps the rudder immersed and increases lateral area aft, while trimming by the bow increases yawing risk. Increasing GM affects rolling stiffness, not yawing, and shifting weights to the bow exacerbates yawing.
