When a semisubmersible rig under tow veers from side to side on its tow line, the best way of controlling the action is to __________.

Correct Answer: Option A — trim by the stern

Trimming a semisubmersible by the stern increases directional stability and hydrodynamic damping aft, reducing yaw and side-to-side veering on the tow line. This practice aligns with standard MODU towing seamanship to maintain a straight and stable wake.
