The Cromwell Cup Regatta, named after Riverside Boat Club [RBC] member and 1964 Olympian Seymour Cromwell, is the largest summer regatta held on the Charles River. Attracting rowers of all ages and skill levels, this regatta is run entirely by RBC volunteers. In 2010, we hosted rowers from 39 clubs and representing eight states. Riverside's goal by hosting this regatta is to encourage friendly competition on the Charles River and build awareness of rowing in the Boston/Cambridge community.
