Now in its 10th year. Paddlers from around the world come for the challenge on the water, the beauty of Manhattan and the camaraderie in paddling for a cause. The SEA Paddle NYC serves as Surfers’ Environmental Alliance’s primary fundraiser. The Paddle and ancillary events raise money for environmental preservation and a number of non-profit autism organizations, bringing awareness to and supporting the causes closest to SEA’s core values. seapaddlenyc.org
