We are a UK charity, managed by a small team of volunteers who love the UK’s seas, shores and wildlife.


Our oceans are in trouble from overfishing, pollution, lack of protection, and climate change. We need to act now to protect the oceans for the future.


Our vision is to create a world where the seas and shores are clean and healthy and marine species are protected.


  • To harness people’s love for the sea, inspiring them to contribute positively to its sustainability.

  • To enable businesses that care about the marine environment to make a difference.

  • To fund grassroots marine conservation projects through business partnerships.


  • To enable grassroots, community-led marine conservation to happen all around the UK’s shores and coasts.

  • To create communities of Sea-Changers – people who care about the seas, are willing to take practical actions to make a difference, and have the funds they need to put their plans in to action.  



Guy is known as a writer, journalist and television presenter, but these days you are more likely to find him with his crew, collecting hand-dived scallops around the coast of Mull.

He says, "I care passionately about the health of our seas and it is fantastic to find people who want to do something to support marine conservation in the UK. I hope many more will become involved through the great work of Sea-Changers.”


Maya Plass is a marine ecology and coastal expert, writer and TV presenter, who can be seen on BBC’s Springwatch and Autumnwatch. She has a BSc Marine Biology and Coastal Ecology, and an MSc Integrated Coastal Zone Management and she runs her own marine education business, Learn to Sea.


She says, “Sea-Changers is an incredibly exciting charity that helps allow sea-users and businesses to actively support marine conservation. I am delighted to join the Sea-Changers team to help make our mutual dream of better-conserved seas a reality!"


Theo Stocker,  sailor, writer and environmental enthusiast is editor of Yachting Monthly Magazine and was a founding trustee for Sea-Changers. 

Theo says: “It is a privilege to be a Patron for Sea-Changers. It is clear that we as humans have had a huge impact on the marine environment, and it is great to see Sea-Changers taking action by supporting charities, initiatives and grass-roots marine conservation projects. By supporting Sea-Changers, sailors can help protect the environment we all love so much and I hope I can encourage more sailors to do just that.”






Co-founder Helen Webb is responsible for developing fundraising relationships and managing the Sea-Changers’ grant programme. This is a voluntary role, which she does when she’s not working as a Learning and Development Specialist. Helen says, “I learned to scuba dive in 2002, but I didn’t realise what a life-changing hobby it would become. After a few years of diving, it became clear that the sea was experiencing some very serious problems. My concern resulted in action, and with the support of some fantastic people, Sea-Changers was born.”



Beth has volunteered on a range of marine conservation initiatives in the UK and overseas, and is passionate about the impact that grassroots action can have on the global marine conservation effort. Having spent her early career in marketing, she ditched the 9-to-5 in 2012 to work as a diving instructor in Bali, and went on to help set up a marine conservation programme in Raja Ampat. She returned to the UK to complete an MSc in Applied Marine Science, and then managed the Marine Recreational Impacts Project for the Plymouth Sound & Tamar Estuaries MPA. She is currently Senior Policy Advisor for Marine Sustainability at Defra.
