Welcome to New England Marathon Swimming Association (NEMSA)

We have been swimming, recreating, and just plain enjoying the waters of New England for 30 years. From Booth Bay to Narragansett Bay we've immersed ourselves in the role of not only participant, but watch guard over the quality of New England's waters. We've seen cause to celebrate with a swim in a clean Gloucester Harbor. Our members have participated in some great open water swims, where only a decade or two ago few would dare to jump in because of poor water quality.

NEMSA was formed to ensure these opportunities will be here for the future as defined in our mission. If you love to swim in New England's open water, whether river, pond, lake, harbor, bay, sound, or ocean, then your membership will not only help you connect with like minded individuals, it will help promote awareness of the need for continued vigilance over the quality of our most precious natural resource.
