We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

I wonder if the joint stiffnesses near the bow are not realistic (too big)?  As I mentione previously, I do not have the experience on how to distribute the known percentage of the critical pitch damping due to viscous effect of the whole ship on all the sections of the ship.  Have you tried to do the calculation without these equivalent pitch damping?  If the damping has less effect on the heave RAOs, it could be the problem from the joint stiffness.
