It saved Ham from the water, not from Hell.

Gen 9:24 When Noah awoke from his wine and knew what his youngest son had done to him,
Gen 9:25 he said, "Cursed be Canaan; a servant of servants shall he be to his brothers."
Gen 9:26 He also said, "Blessed be the LORD, the God of Shem; and let Canaan be his servant.
Gen 9:27 May God enlarge Japheth, and let him dwell in the tents of Shem, and let Canaan be his servant."
