ULTRAMARINE IS BACK! For the past 6 years, we’ve brought some of the world’s brightest minds to Sir Richard Branson’s Necker Island with a Mission to protect 30% of the ocean by 2030. We’re at it again.

Join Nautilus and partners on April 8-12, 2025, as we plot to build a global nature-based economy. During this summit, attendees will plan strategy and implementation to protect large areas of the ocean by bringing markets to nature.

The ULTRAMARINE Summit brings ocean advocates from around the world to focus on action. The event happens on Sir Richard Branson’s private island, and for 6 years it has proved to be the perfect environment for making global change. You’ll gather with a carefully selected group of 50 other Nautilus members and leaders. For the first time ever, we’re granting each attendee a Nautilus VIP Membership, which includes complimentary tickets to all Nautilus events, and more.

And, for a little added excitement, this year we have a special collaboration with composer Brian Eno’s Sounds Right Campaign to bring a live concert to the Island on the last day of our gathering. Performers to be announced soon.

If you want to be part of sweeping change towards a healthy ocean, YOU DO NOT WANT TO MISS THIS! Will you join us? Apply below.
