What midshipto antelope,thw ship of Gulliver,onits voyage to High seas ?

The ship encounters violent storms, has bad food, and weakens the crew (twelve crew members die) when the ship hits a rock and is split. Six of the crew members, including Gulliver, get into a small boat and row until they are overturned by a "sudden Flurry." Gulliver swims until he is nearly exhausted, at which point he finds an island, comes across a patch of grass, and sleeps for what he estimates is more than nine hours.
