Your vessel is damaged, listing to port and on occasion flopping to the same angle to starboard. It has a long, slow, sluggish roll around the angle of list. There is excessive trim by the stern with little freeboard aft. What action should you take FIRST to correct this situation?
• Free surface effect in slack tanks and its impact on stability (GM and roll behavior) • Difference between correcting list (heel due to off-center weight) and trim (bow-stern balance) • How after trim and low freeboard aft affect safety and what change in tank condition would improve this
• Based on the description of the roll (long, slow, sluggish) and behavior around the angle of list, what does that tell you about the vessel’s GM and presence of slack tanks? • Which action directly reduces free surface where it is most dangerous in this scenario, and also improves the low freeboard condition aft? • Which options might actually make the list or stability worse by increasing free surface or moving weight in the wrong direction?
• Identify which choice directly reduces free surface in AFTER slack tanks rather than creating more slack tanks. • Check which option will improve freeboard aft instead of reducing it further. • Eliminate any choices that focus mainly on changing trim only without addressing the clear signs of poor stability and free surface.
