My taste buds are going for it! It's extremely evocative! But my right lobe is fighting it.
I believe that on the sides,the flow will separate and everything will be embedded within turbulence at a base pressure commensurate with the point of separation.The foil would provide some cleanup as it 'forces' some of the wake architecture,but unless it was purely airtight all around I'm afraid that it would not perform as well.
And without a 'back wall' the base of the wake would be no smaller,which violates the tenets of boat tailing.
Beautiful Photo Shop work!
