Basics: Trim & Stability – Stiff vs. Tender Ships ⚓ Let’s make stability simple: It all comes down to your ship’s GM (Metacentric Height). ✅ Tender Ship – Low GM – Short righting lever – Rolls slowly but more dangerously – Less stable in rough seas ✅ Stiff Ship – High GM – Long righting lever – Quick, sharp rolls – Feels stable but uncomfortable Balance is key! Too tender = unsafe. Too stiff = stressful for crew & cargo. Know your GM. Understand your behavior. Stay stable out there! #TrimAndStab
