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.


Swim Across America began as a relay swim from Nantucket to Hyannis and has evolved to 21 open water swims and dozens of pool swims around the country. We are continuing the tradition of SAA on Nantucket with another swim this July.

Join hundreds of swimmers (including Olympians) at a gorgeous venue for a day to remember this July. Choose from 1/4 mile, 1/2 mile, 1 mile or Kids' Splash options on July 25th or take part in the 4 mile distance on July 23rd. Be a part of this landmark event this summer!

If you have any questions about SAA - Nantucket, please contact Jill Roethke or Jim Pignato.


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 Swimmer: $1,000 minimum:

WaveMakers are elite SAA fundraisers and go above and beyond the call of duty by pledging to raise at least $1,000 regardless of your age. You can sign up for any of the distances. WaveMakers get an exclusive WM gift and access to the WM village on event day where they will have access to other perks and swag.

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. The swim will take place on Thursday July 23rd. Swimmers will need to be on island by the previous day 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. Any swimmer in the water after three hours 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 Four mile swimmers will be invited to participate in the one mile swim on Saturday July 25th and participate in all of the event day festivities.

Transportation and Lodging

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.
