Too tender = unsafe. Too stiff = stressful for crew & cargo. Know your GM. Understand your behavior. Stay stable out there! #TrimAndStab

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
