All - I recently emailed the German Frers firm to see if they, as the vessel designer, could tell me what either the Limit of Positive Stability (LPS) or the Angle of Vanishing Stability (AVS) is for the H46. They quickly responded with the attached "Stability and Hydrostatics Datasheet" for the H46. Thought folks might want to see it.
