Nantucket Cottage Hospital, Palliative and Supportive Care of Nantucket, Mass General Cancer Center

Welcome to the Swim Across America - Nantucket Open Water Swim! Since 2013, SAA - Nantucket has raised nearly $5 million for our beneficiaries: Nantucket Cottage Hospital (NCH), Palliative and Supportive Care of Nantucket (PASCON), and Mass General Cancer Center (MGB). Thank you for your support of cancer care on Nantucket Island, and groundbreaking research at MGB.

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 27th 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 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 Saturday July 27th with an inclement weather date of Sunday July 28th. An in-person pre-race meeting will take place on Thursday July 25th. 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.

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

Nantucket Cottage Hospital Program Details

This program allows island cancer patients to receive oncology services at Nantucket Cottage Hospital (NCH) rather than the mainland, saving them from burdensome and expensive travel while suffering from cancer. With the collaboration between the Mass General Hospital (MGH) Cancer Center and NCH's oncology department, patients are able to receive an academic level of care in a rural community hospital. The MGH link also brings access to breakthrough and state of the art technologies, drug therapies and clinical trials that would not be available to a rural community hospital. 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. Services, including chemotherapy, are performed at the Swim Across America Infusion Center at NCH.

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 RN-Nurse Specialist, a Palliative Care Counselor, Social Workers, Program Assistant, Chaplain, Medical Director, and volunteers and is provided in any setting. Cancer support groups are also conducted twice/month. Services are provided free of charge and are fully supported through donations and grants. PASCON staff works directly with the NCH oncology staff to ensure the needs of all patients are being met.

MassGeneral Cancer Center Program Details

Proceeds from SAA-Nantucket will support the research of Dr. Bryan Choi, MD, PhD., who specializes in surgical care for patients with benign and malignant brain tumors. He also leads a research laboratory with the goal of developing the next generation of cell therapies and clinical trials in neuro-oncology. Learn about Dr. Choi's research on our blog.

"Our team at Nantucket Cottage Hospital wanted to give the opportunity for staff members who are not interested in swimming an option to participate in the Swim Across America mission. We decided that the best way to do this was a team walk! Nantucket, being the small island that it is has a few distinct villages that we decided to pick a road that is one of the longest on island. Starting in the sleepy village of Sconset we walked the seven miles to the main rotary on island. Team members had the option to walk the whole seven miles or meet the group along the way and walk for however long they wished. We had a total of around 20 participants and most walked the whole distance. We all wore Swim Across America gear to give the awareness to the community members we passed on the way either in their cars or on the bike path. It was a nice way to involve new team members who may feel intimidated by an open water swim!"



SAA-Nantucket has secured 10 bibs to participate in the Falmouth Road Race on August 18, 2024. The Falmouth Road Race was established in 1973 and has become one of the premier running events of the summer season. Each year the race draws an international field of Olympians, elite, and recreational runners out to enjoy the iconic 7-mile seaside course. The registration fee is $200 and each runner is required to raise an additional $1,000. Once receiving a bib number, runners are to register on the SAA-Nantucket website as a Runner. Runners will receive a unique runner jersey and will qualify for Wavemaker status after raising $1,000. For more information on the Falmouth Road Race please contact Erin Myers.
