Sunday at 12:30 p.m., following the Antique & Classic Boat Rendezvous, the classic vessels will take part in a jubilant, three-mile parade down the historic Mystic River. Each boat will be announced on the shore at Mystic River Park as it passes through the iconic bascule bridge. The spectacular boats and their costumed crews will make their way down river to Fishers Island Sound in what has become a highlight of the Mystic summer season.
