How was gulliver able to reach the strange island of Laputa?

After being at home for only ten days, Gulliver is visited by a ship captain who invites him on a voyage departing in two months. Gulliver convinces his wife that this is a good opportunity and sets off, again working as the surgeon.

After they sail for three days, a storm arises, driving the ship to the north-northeast, where they are attacked by pirates. They are unable to defend themselves. Gulliver insults the captain of the pirate ship and as punishment is set adrift in "a small Canoe, with Paddles and a Sail, and four Days Provisions." On the fifth day of sailing in his canoe, Gulliver reaches a small island ,Laputa, where he spends the night in restless sleep.
