Angle of loll

Angle of loll is the steady heel taken up by a ship with negative initial $GM$ that rolls to one side until $GZ$ becomes positive again. Unlike a list, it is symmetric (the ship can flop to either side) and signals a stability defect, not a weight offset. The cause is usually a raised KG from consumed bottom fuel or free surface; correction means lowering G or removing free surface, never simply ballasting the low side, which can deepen the loll.
