The MK III from the MK II is different in that it does not have the aft lazerette.  There are some additional storage spaces under the quarter births and the Keel winch is on the aft side of the mast compression post.  There is also a little shelf/ledge running around the sides.  There are no external differences between a MK II and a MK III.
