Oh and btw, Since the trade routes get so juicy near the later stages of the game and health becomes an issue in later stages, the placement one tile from the coast does not typically become an issue until the late stages. If you need the city for short term gain then one tile of the coast is fine, but a good tile alone - say gold of corn - will not compensate for the long term loss. Short term the gold or corn is better than coastal + missing that tile, long term it is worse imo.
