Recognizing insufficient stability in a ship, particularly related to a small GM (metacentric height), involves observing various symptoms and indicators. Here are key signs to watch for:
Excessive Rolling: If the ship exhibits excessive rolling or a slow return to an upright position after a roll, it may indicate insufficient stability. A small GM results in a less effective restoring force.
Difficulty in Handling: The ship may become difficult to handle or maneuver, especially in rough seas, because of poor stability.
Shifting Cargo: If cargo or equipment shifts noticeably while underway, it might suggest inadequate stability. Properly balanced cargo is essential for maintaining stability.
Increased Draft Changes: Significant changes in draft or trim while the ship is operating can indicate stability issues.
Poor Performance in Weather: The ship may struggle more than usual in adverse weather conditions, exhibiting excessive rolling or pitching.
Deck Wetness: Excessive water on deck, particularly on one side, can indicate poor stability.
Difficulty with Stability Calculations: If stability calculations frequently show marginal or insufficient stability, it suggests a small GM or other stability issues.
Crew Feedback: Crew members might report unusual behavior of the vessel or difficulties in normal operations, which can be a sign of stability issues.
If any of these symptoms are observed, it’s essential to take corrective actions immediately, such as redistributing weight, adjusting ballast, or seeking advice from a marine surveyor or stability expert to ensure the safety and stability of the ship.
