A marine vessel in-water stability test using a crane to roll the vessel 360 degrees, often referred to as a full-scale roll test, is typically conducted on specialized vessels, such as lifeboats or rescue vessels, to verify their self-righting capabilities. The process is significantly more rigorous than the typical inclining experiment and tests a vessel's ability to return to an upright position after being rolled over. Here's a detailed breakdown of the process: 1. Preparation: Securing the

⚓ Master Ship Stability Like a Pro! Understanding ship stability isn’t just theory—it’s life at sea. From small rolls to heavy waves, knowing your ship’s initial, dynamic, and longitudinal stability can keep you safe and efficient on deck. 🟦 Initial Stability (GM): Safety at small angles of heel 🟨 Dynamic Stability: Survival in heavy seas 🟥 Longitudinal Stability: Trim, propulsion, and manoeuvring efficiency ⚖️ Factors affecting stability: cargo distribution, free surface effect, ballast cond
