Brought to you by Maui Nui Swim- The leader in Hawaiian Channel swimming
To learn more about reducing cookiecutter shark attacks check out the recent interview with Steven Minaglia on Hawaiʻi News Now. Read the 2024 publicly available research about cookiecutter sharks in Hawaiian waters made possible by data collected by HCSA and analyzed by Maui Nui Swim here. Listen to the March 2024 interview on Hawaiʻi Public Radio here.
Following the February 21, 2024 publication of its research Maui Nui Swim adopted what it considered to be the most effective risk-reducing strategy for avoiding cookiecutter shark attacks. Using compreshensive analysis of swimmer ability and environmental factors departure times were calculated to place swimmers in the deep part of the channel with the sun up and to reduce night swimming time on both the front and back ends.

The Maui Nui Swim Advantage
Expert consulting for your Molokaʻi Channel crossing
Why book any Hawaiian Channel crossing with Maui Nui Swim? We know the level of commitment and resources necessary to swim a channel, especially the Molokaʻi (Kaiwi) Channel and especially the pressures of completing Oceans 7. Help with logistics like where to train, where to stay, and how to get around are easy to find online and are featured below. At Maui Nui Swim we provide comprehensive consulting that includes information on ocean conditions, tides, currents, and marine life based on contemporary research. We plan departure times and locations around the individual swimmer, particularly the swimmer's safety, ability and goals. The captains we affiliate with are active partners and have final say when it comes to swimmer and crew safety on the water. Maui Nui Swim has access to a fleet of boats and crews for swimming the Molokaʻi (Kaiwi) Channel and remains highly selective on who it accepts. Serious applicants only may apply.
Where to swim:
Honolulu offers a variety of options to prepare for your upcoming channel crossing. We recommend getting familiar with the temperature and salinity of our ocean before your swim. Ala Moana Beach Park and Kaimana Beach are excellent venues to log in some swims and acclimate to the local conditions while on Oʻahu. Looking for someone to swim with contact us.
Hawaiʻi is also home to a large number of outdoor, long course meter format pools that are free of charge to the public. For a complete listing visit the Department of Parks and Recreation. There is also Cooke Memorial Pool on Molokaʻi.
Where to stay:
We recommend lodging in and around Waikiki while on Oʻahu. For your Molokaʻi stay we recommend Hotel Molokaʻi as the restaurant is open for breakfast, lunch and dinner and offers a wide variety of healthy foods. Kaluakoi Villas near Kepuhi Beach are also an option on Molokaʻi. As of 2025 Maui Nui Swim offers a premium package with lodging that is walking distance to your departure beach off the western shore of Molokaʻi during select windows.
How to get around on Oʻahu:
Maui Nui Swim can hook you up with a private vehicle on both Oʻahu and Molokaʻi. In general it is best to have your own vehicle. Honolulu offers access to most rental companies and Uber is ubiquitous on Oʻahu.
How to get to Molokaʻi:
You can take a boat but this is not advised if you plan to start your swim once you arrive in Molokaʻi. Mokulele Airlines is the carrier that offers flights between Oʻahu and Molokaʻi.
How to get around on Molokaʻi:
Maui Nui Swim can hook you up with a private vehicle on both Oʻahu and Molokaʻi. On Molokaʻi it is best to have your own vehicle unless it works out that you only need to get from the airport (MKK) to your starting point. In that case the local taxi service takes reservations here. There is no Uber or Lyft on Molokaʻi.
Swim Ratification:
Maui Nui Swim works closely with the Hawaiian Channel Swimming Association (HCSA). Book your swim with Maui Nui Swim, successfully complete it according to HCSA's rules, and receive your official HCSA cap and certificate for free. Outside of Maui Nui Swim fees will apply.
Does my swim count for Oceans 7?:
Yes- just ask anyone that booked with Maui Nui Swim like the Zemaitis Brothers, Legendary Oʻahu Swimmers Colby Dimsdale and Tim Lorge and Olympians Petar Stoychev and Andreas Waschburger.
Membership:
You do not have to become a member of any association to ratify your successful swim. The good news is that if you complete any channel crossing in Hawaiʻi then you automatically become a member of HCSA. Effective 2025 HCSA now offers unique privleges to members.

"Dr. Steve's Picks"
2025 Season Molokaʻi (Kaiwi) Channel Swim Windows
Created by Maui Nui Swim
Each summer Steven Minaglia creator of the Maui Nui Swim suggests optimal Molokaʻi (Kaiwi) Channel swim windows based on experience and current science including an analysis of over 900 channel crosses in Hawaiʻi. These windows are individually created with the swimmer and the swimmer's safety in mind.
Urgent update: since the peer reviewed publication of the research on cookiecutter sharks (see below) there have been 21 successful Molokaʻi Channel swim crosses and 2 individuals attacked by cookiecutter sharks. Further analysis using the methods described in this research demonstrates an even stronger association between cookiecutter shark attacks on live humans and moonless nights (p=0.002 RR 15.3 (1.9-123.2). This means there is a minimum 90% increased risk of a cookiecutter shark bite when swimmers transit the deep part of the channel at night and without the moon in the sky. The warning to swimmers issued February 2024 is therefore again repeated: do not start your swim at a time that places you in the deep portion of the channel at night without the moon. Furthermore these data do not support a protective effect of shark deterrent devices. While there are no guarantees that a swimmer will not encounter a shark with the moon in the sky it is highly advised to use all available knowledge to promote the safety of the swimmer.
