Hello,
In calculating the cross curves of stability what happens when the deck edge goes under water? Is the righting arm calculated as if the vessel simply rotates about the center line at various angles? For example, a barge at 10 - 20 degrees will have the deck edge under water. Yet the cross curves of stability are calculated out to 90 degrees. Or is the new buoyancy equilibrium found then the righting arm? I have a few good naval architecture references as well as several from the internet but this point is not clear to me.
thanks, Jeff
