By day, yes.. but by night, it's not relevant. Night VFR does not depend solely upon position fixing by ground or water - refer posts above.
Under NVFR you must assume the 8/8ths fog (and various other monsters) are waiting for you below your LSALT and be competent to navigate by other means. That's why NFVR is a Rating, not simply an endorsement.
