Why didn't Odysseus drown in book 5 of the Odyssey?

Odysseus didn't drown in Book 5 of The Odyssey because the goddess Ino, also known as Leucothea, provided him with a magical veil that kept him afloat as he swam to the shore of the island of Scheria. Ino took pity on Odysseus and helped him survive the storm at sea.
