FWIW a loose foot or shelf foot makes no difference as the point of maximum draft is 'set' by the amount of 'broadseaming' (tapered seams from midcord forward).
A 'racing cut' sail has a flattish 'entry' roundness (about the first 1/3 of the cord length) but requires *precise* steering/trimming; a 'cruising cut' has a 'rounded' luff shape and is 'forgiving' for the helmsman but is vulnerable to so-called 'backwinding' if the amount of draft, etc. is too great.
