This is because the rule has a one design mast which effectively limits the amount of righting moment one can have.
So, with twin rudders and a canting keel this leaves two appendages to be fitted to the boat--meaning the foils used in the IMOCA fleet had to provide side force for when the keel was canted and then try and develop lift as opposed to righting moment, with the exception of Hugo Boss who went narrower and therefore the hull was not producing as much stability and so there was room to develop foils which could create righting moment as well as lift.
