I knew a ship owner with an old boat that was perfectly functional. After a USCG inspection, the owner was suddenly forced to do a completely new stability test for the vessel and create a whole host of new documentation. Why? The owner suffered from stability decay.
Stability decay: dreaded words. Did you know that a perfectly stable vessel can become unstable and useless? Its insidious. It slowly creeps up and destroys the vessel stability. In this video, I cover the three essential things you need to know for stability decay.
Stability decay comes from weight changes to the ship. These weight changes can be summarized as three basic rules to remember.
So how can you control these weight changes? The best prevention is recording the weight changes. You need to maintain a written records of any permanent weight changes to the vessel. Record the following items.
Why should you record these weight changes? They give you control and allow you to predict when you will need a new stability test.
