Our trustees

Our trustees govern the charity. They're unpaid volunteers with a wide range of skills and experience who share our passion for the ocean.

Each year, our Board reviews its effectiveness and carries out a skills analysis. When there is a vacancy for a trustee, we advertise for people with the skills and experience needed. We then hold interviews before selecting a candidate. Each candidate is then proposed to our members for election at the Annual General Meeting.

Our trustees serve three-year terms. While they can offer themselves for re-election at the Annual General Meeting, each trustee’s total term is limited to make opportunities for new people to join the Board.

Be our new Chair

As of May 2026, we're looking for someone to take the helm of our Board of Trustees - an experienced leader who brings both the credibility to chair a dynamic charity and a genuine passion for what we're trying to achieve for our ocean. Please visit GatenbySanderson to learn more about the role.
