Transcript of KN tables

KN tables / Cross curves (including an example)This will take the form of a diagram or table showing the righting levers for an assumed KG (the KN is the GZ of the vessel assuming the KG is zero). There should also be a worked example showing how a GZ curve can be obtained using the tables / cross curves.KN tables are used to obtain the value of GZ (as GZ = KN=-KGsinθ)Cross curves are used to find the GZ of the vessel for any angle of heel.KN tables / Cross curves (including an example)This will take the form of a diagram or table showing the righting levers for an assumed KG (the KN is the GZ of the vessel assuming the KG is zero).
