Powerboats racing in large groups at high speeds through the Bay.  Typically start at Braga Bridge in Fall River, then head to East Providence YC to pickup 1st card, then go to Warwick for 2nd card.  Then they go to West Wind Marina in Newport for 3rd card, then to Thames St public dock in Bristol for 4th card, then back to Tipsy Seagull in Fall River for 5th and final card.
