The race that took place in the Corpus Christi Marina on Thursday involved radio-controlled versions of the full size J-22s they sail. These are 1/16th the size of a regular J-22, and there are only three in existence. Jack Lischer, 20, from Kansas City won the race. He says he spent his childhood playing video games and sailing which prepared him for this race.
