Welcome to the Swim Across America - Nantucket Island Open Water Swim.
Swimmers of all ages and skill levels are invited to take part in our annual event at beautiful Jetties Beach and help us support cancer treatment and patient care on Nantucket Island.


Welcome to the Swim Across America - Nantucket Open Water Swim! SAA - Nantucket has raised over $3 million over the past eight years for our beneficiaries: Nantucket Cottage Hospital and Palliative and Supportive Care of Nantucket. Thank you for your support of cancer care on Natucket Island.

Each year we are proud to host over 400 swimmers and volunteers, spectators and supporters, as well as Olympians near and far at our charity swim. We are so excited to have you join us for our annual swim on July 24th on Nantucket Island!

Whether you are a veteran swimmer or you're looking to do your first open water swim, we welcome you to help us "Make Waves to Fight Cancer."

Swim Across America is dedicated to providing a safe return to events in 2021.

Nantucket Cottage Hospital Program Details

This program allows island cancer patients to receive oncology services at Nantucket Cottage Hospital rather than the mainland, saving them from burdensome and expensive travel while suffering from cancer. The program brings a team of cancer specialists to the island every week for patient consultations. In addition, a Board Certified Advanced Practice Oncology Registered Nurse is on-site to see cancer patients five days a week.

Palliative and Supportive Care of Nantucket Program Details

This program provides direct care and services to patients and families who are coping with cancer. Care is provided through a Nurse Practitioner, a part time APRN Oncology NP, Palliative Care Counselors, Social Workers, Program Assistant, Chaplain, Medical Director, and volunteers and is provided in any setting. Services are provided free of charge and are fully supported through donations and grants.

Swim as an Individual, or on a Team:

A person may elect to swim alone, or be part of a team. Many colleagues will form teams, or teams may be formed in honor or memory of a loved one. All teams are inspirational and rewarding for all of us involved with Swim Across America. Teams must have a minimum of 3 swimmers and each swimmer is still required to meet the individual fundraising minimum of $200. Each team has a fundraising minimum of $1,000.

WaveMaker Status: $1,000 minimum:

WaveMakers go above and beyond the call of duty by raising at least $1,000 regardless of your age. Anyone can achieve WaveMaker status - swimmers, volunteers or SAA My Way participants. WaveMakers get special recognition and an exclusive WM gift on event day. You can learn more about WaveMaker Status here.

Kids' Splash:

Swimmers ages 6-11 (exceptions made by the event director) are invited to join us for a Kids' Splash before the 1 milers start their swim. Kid swimmers will swim a short swim (about 50 yards) in the water to take part in the event. Kids must be able to swim 50 yards to enter the swim.

There is a $25 registration fee to take part in the Kids' Splash and we ask that you sign up ahead of time. The minimum fundraising requirement is $50 ($25 fee included). To register, click on the register on the home tab. Then you'll be able to select the Kids' Splash option.

Four-Mile Swim Experience:

We will host a four-mile swim along the North Shore of Nantucket. The swim will be limited to the first 12 registered four mile swimmers to raise $4,000 and to the first 12 registered 2x2 mile teams to raise $5,000 (each individual to raise $2,500). The swim will take place on Sunday July 25th. Swimmers will need to be on island a few days early to attend a pre-swim meeting. Each swimmer must provide his or her own kayaker and be able to complete the swim within three hours. Relay swimmers will share the same kayaker who will kayak the entire 4 mile course. Any swimmer in the water after three hours (or 1 1/2 hours for the 2 mile relay legs) may be pulled from the course at the discretion of the SAA Safety Director and/or Co-Event directors. The alternate dates in case of inclement weather are TBA.

Swimmers will verify their one mile swim time and past open water experience with Co-Event directors prior to the swim (email

Nantucket is easily reachable year round by ferry boat or plane service. During the busy summer season, the town encourages visitors to limit bringing their cars over by providing a seasonal shuttle system giving the community an essential transportation option around the island. There are miles of town maintained by bike paths, town owned beaches & beautiful harbors for moorings all enhancing the experience on the island. From the beautiful sunsets of Madaket to the charming small village of Siasconset, the public can view the beautiful landscapes, historic homes or wide spread beaches until reaching their special and personal Nantucket destination.
