Our trustees govern the charity. They are 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.

Our Chair – Amanda Nobbs

Chairing the Thames Regional Flood and Coastal Committee for eight years, she transformed the way partners worked together and now champions a joined-up approach including politicians, businesses, communities and partners.
