Your vessel has run aground and is touching bottom for the first one-quarter of its length. What is the LEAST desirable method from the standpoint of stability to decrease the bottom pressure?

🔍 Key Concepts

• Longitudinal stability and trim when a vessel is aground forward • How removing weight forward versus adding/ shifting weight aft affects trim and ground reaction • Effect of pumping out vs flooding tanks on overall displacement and stability

💭 Think About

• If the vessel is aground at the forward quarter, what happens to trim when you remove weight from the bow compared to when you add weight aft? • Which actions will tend to pivot the ship more firmly on the grounded area, and which will tend to lift the bow or reduce ground reaction? • How does flooding a tank (adding weight) versus discharging cargo or pumping out a tank (removing weight) generally affect stability and draft?

✅ Before You Answer

• Identify which options remove weight forward and which add or shift weight aft • Consider which option most increases trim by the head or tends to press the bow down further • Check which method could reduce overall stability (GM) the most while also worsening the vessel’s grounding condition
