Meet our Crew

Holly Manvell 🇬🇧

Founder and Skipper

Like many, Holly's first taste of sailing was in the Optimist. Capsizing (repeatedly) in cold reservoir water however, wasn't something she relished, and so over the years switched to keelboat sailing.

Holly is a keen sailor with many nautical miles under her belt. Combining her passion for oceanography and geography, and love for sailing, she set up Clean Sailors to engage fellow sailors and water-lovers in safeguarding the future of their passion – the sea.  

Holly's interest in our world has seen her work with various international development organisations on climate, population, and air and water quality. Her core background is in business, from private-equity ownership to listed companies, and she's an Ocean Conservation Trust Advocate and Henri-Lloyd Pioneer.

Charlie Hayward 🇬🇧

Co-Skipper

Charlie took up sailing relatively late compared to most. Starting off with Wayfarers as a teenager he then transitioned heavily to keelboat sailing and racing. He's sailed much of the UK's south coast waters alongside regular trips to the western Irish coast and Europe.

Lately, he's competed in some of the classic yacht racing events including Round the Island and St. Malo and back in 2015, successfully completed a 51-day, east-west crossing of the Atlantic Ocean in a rowing boat. It was during this voyage in particular that Charlie frequently saw man-made debris in the vastness of the world's second-largest ocean and vowed to help reduce the impact we have on our seas. Charlie works in impact investing and joined our team aligning his two passions - sailing and cleaning up our seas, with ours.

Libby Allen 🇬🇧

Crew

Libby is scientist, specialising in microplastics. She helps us understand and communicate the impact we humans are having on our oceans; plastics in particular. She's a Master in Oceanography and is currently studying for her PhD, having done various studies on microplastics including nurdles and microfibres.

By 13 years old, Libby was competing in sailing across the UK and became the youngest person ever to win a National Championship race in the double-handed Enterprise dinghy class. Her favourite memory on the water is racing under the Sydney Harbour bridge.

Libby is also a sailing and SUP instructor, and loves inspiring her students to not only get out on the water, but to protect it, also.
