The CB location of the boat (also somewhere to the left of the hulls since the mast in the water contributes to it)
Disagree. What center of balance you mean? There is an axis of rotation that is on the hull, it changes somehow as the boat rotates but is always on the hull. The center of balance that you are probably referring is what you then call the combined CG of the boat plus the person which will never be to the right or to the left because it´s the same thing..
