He is raising money for his trip with a GoFundMe, "Solo across the Pacific Ocean: row for Ukraine." Funds raised will go to the organization founded by Mockus to help him complete his journey. "Everything is possible if you want," Mockus said. "The best news I can hope for is when the journey is over is to hear that the war in Ukraine is over."
