Every year Berk held a Regatta as a means to blow off steam before the Vikings lost their cool. It was a sporting event for which the village decorated banners, set up stands, and hyped up to watch the boats sail "sloooowly across the harbor", as Hiccup puts it. After the teens learn to ride dragons however, they find an even more exciting way to blow off steam, that being Dragon Racing. The Regatta appears to have been replaced with Dragon Racing from that year onward.
