The two adventurers - Kārlis Bardelis and Gints Barkovskis, departed from Luderitz in Namibia. They plan on crossing the Atlantic in 90 days.
Their boat, 7 meters long and 2 meters wide, reportedly has enough supplies to last them throughout the ride. It's fitted with a system for producing drinking water.
In 2013 Bardelis crossed Europe on inline-skates in 60 days in what could be the longest ride on such skates ever.
