HLM’s 35th annual Head of the Weir River Race is a celebration of the estuary at the height of its fall beauty and the fabulous array of the region’s open water rowers. As many as 60 boats jockey for position racing out of the narrow estuary and onto open water, traveling from West Corner (on the Hull/Hingham/Cohasset line), past Bumpkin Island, across Hull Bay, to the museum’s Windmill Point Boathouse at Hull Gut.
