The Hudson River Watertrail Association is a coalition of small boaters, primarily human and wind powered, who are actively interested in the Hudson River as a treasure of natural and human history. The HRWA was formed in 1992 as an all-volunteer, non-profit environmental and recreational action group, with the specific goal of building a river trail from the Atlantic Ocean to Canada and promoting a low impact approach to the river. The group was born of the realization that the Hudson River was difficult to access or actively use by small car-top boaters, including those interested in multi-day trips on the river.
