The Australian Maritime Safety Authority says it's amazing a Dutch adventurer is in such good health after his rowboat was swamped by a tanker in the Indian Ocean.
Ralph Tuijn, 41, left the coast of Western Australia in August on an attempt to be the first solo rower to reach Africa.
The ABC reports he activated an emergency beacon on Thursday morning after his boat was overturned by waves generated by an oil tanker west of the Cocos Islands.
The AMSA said he was rescued by the LNG Sokoto, a merchant vessel, about an hour later and was in good spirits.
The Dutchman previously rowed from Peru to Papua New Guinea.
