The Maui Channel Swim, a top 100 open water swim is held annually on Saturday of Labor Day weekend. It is the longest open water relay swim race in the world, dating back to 1972. Ian Emberson, a Kauai resident and founding Ironman swimmer, has been coordinating the race for nearly 40 years, along with his wife Coco.  The channel swim starts at "Club Lanai", on the island of Lanai, and crosses the Au Au Channel to Black Rock at the Kaanapali Beach Resort on the island of Maui. The distance between start and finish as "the bird flies" is approximately 9.6 miles. This channel is clear, warm, beautiful, open water notorious for its swift currents. Some years dolphins have graced the swimmers by encircling the race clear across the channel.

The relay race is timed and there are six swimmers per team (unless registered as a solo swimmer). At the start of the race, each swimmer swims a thirty minute leg until all team members have raced. Then each swimmer swims ten minute legs until they cross the finish line. Every team has a dedicated escort boat. The boat captain acts as the navigator for each team. Swimmers compete in categories based on the ages and sexes of the team members. The grand prize, a large, perpetual carved koa wood Duke Bowl goes to the first team to finish. Finishers receive impressive collector Hawaiian swim towels. Each swimmer also receives a custom-designed tee shirt.


Swimmers hail from around the world including mainland US, Australia, New Zealand, Japan, Taiwan and Canada. Experience ranges from former and prospective Olympians to recreational swimmers of all ages. The Kaanapali Beach Hotel is the site of the Maui Channel Swim headquarters where swimmers can check in to receive their packets, attend the safety/orientation meeting held the evening before the race, and is the site of the awards banquet. It is also a great spot to hang and watch the gorgeous sunsets! The Maui Channel Swim is family run and so much fun that many of the teams come back year after year and enlist friends and fellow swimmers. There is always a great rivalry between the Australian and American teams. What makes this race so interesting is that the navigation and currents can be a deciding factor. The fastest, strongest team does not always finish first!

The 2023 Lahaina Fires affected many, including beloved MCS escort boat captains, Maui swimmers, hotel and event staff and crews. While MCS 2023 was cancelled, many generous swimmers donated their registration fees to aid fire victims. We are thrilled to share the donations went to the Lahaina Swim Club enabling their young swimmers to compete over the past year. We are so excited to welcome the LSC team who will compete in MCS this year. Wonderful to give back to the community who has hosted the Maui Channel Swim for the past 50 years! Thank you for your generosity!
