Vessel Stability Loadplan Advisor

Advise on ship/boat stability and load planning: estimate displacement, draft, trim, KG/GM and the righting arm, check against stability criteria, and plan cargo/ballast distribution so the vessel floats and rights safely. Use when the user wants to "check vessel stability", "plan a load / stow cargo", "calculate GM / trim / draft", "will the ship be stable", "ballast plan", or "is this loading safe". Advisory only; the master and class-approved booklet govern.
