Catamaran sailors from the U.S., Canada, Puerto Rico, Cuba and the U.S. Virgin Islands are in South Dakota this week competing for a championship.
The Hobie Class Association is holding its North American Championships at Lewis and Clark Lake this week.
Catamarans feature two parallel hulls connected by a single deck. Up to 75 boats will take to the lake for races Monday through Friday. The top team in each class will be named the North American champion.
