It is a beautiful truth of maritime life that vessels, much like the tides themselves, are forever in motion. Today, we proudly celebrate the magnificent legacy and the dignified final chapter of our trusty support vessel—the MV Southern Star.

For many, her signature navy blue hull has been a familiar, comforting sight moored alongside the harbour wall—a symbol of our pioneering spirit and a physical anchor for our commitment to cultivating marine biodiversity. Yet, her story stretches far beyond the Yorkshire coast. She represents a remarkable example of maritime endurance, a testament to the adaptability of ships that have weathered the changing needs of the offshore world for decades.

Born in Newcastle, Australia, in 1973, this extraordinary vessel is a true veteran of the seas. Throughout her long and varied career, she has sailed under a fascinating lineage of names; originally built as the Melbider, she was renamed Lady Of The Isles in 1988, reverted to Melbider in 1995, before finally being christened the Southern Star in 2000. Her operational history is just as diverse. She began her life as a patrol vessel along the North East coast of Australia before serving as a supply vessel navigating the teeming waters of the Great Barrier Reef. Her formidable resilience was further proven when embarking on scientific survey work around the rugged shores of the Falkland Islands, operating for fourteen months in the Cape Verde Islands without shore support, and even transitioning into a maritime security vessel in the Red Sea. She has, without question, earned her legacy.

We had been searching for a vessel to bring to Scarborough to moor alongside and support our operations, primarily to house our seaweed hatchery and offices. The Southern Star caught the discerning eye of our Co-Founder, Cpt Wave Crookes. She had been lying dormant in a shipyard in Clydebank, Glasgow, and it certainly required profound vision to imagine the magnificent headquarters she could become on our coast.

What followed was a resurrection, interspersed by the challenges of a global pandemic and many an adventure across Scotland. Specialist engineers painstakingly restored her mechanical heart, including her two rare Kelvin T8 main propulsion engines—amazingly, brought back to life by the very same engineers who had originally worked on them as apprentices in Glasgow. After meticulous repairs to her hull and rigorous modernisations to her bridge, she was brought home to Scarborough by our crew.

It was an effort of immense determination, bringing together engineers, builders, electricians, designers, and even chefs. Between 2020 and 2024, she was expertly transformed into a scientific hub, offices, education rooms, a thriving café, a restaurant, and a welcoming public visitor centre.

Away from the lively hum of the visitor centre and café, the Southern Star was hard at work as our scientific headquarters. Her lower decks were transformed into our dedicated onboard science laboratories, while her aft deck proudly hosted our seaweed hatchery within a specialised, refrigerated unit. Across this steel facility, our scientific team carefully nurtured the delicate spores that would eventually form our offshore cultivation systems, driving our mission to create rich marine habitat, while our marine crew mobilised for the open sea. Above deck, visitors from across the country arrived to share in our vision.

In 2024 alone, the Southern Star welcomed over 10,000 visitors aboard. She hosted an array of dynamic events, from insightful talks and cooking demonstrations showcasing our seaweed and other local foods, to celebrating our coastal creatives through our 'Artist of the Month' exhibitions and our bustling 2023 Christmas Art Fayre. Overall, an estimated 80,000 people have engaged with our mission simply by passing our vessels on the pier and reading about the remarkable power of seaweed.

The Southern Star was far more than just a vessel; she was a brilliant ambassador for the ocean. She provided a magnificent space where the rigorous science of our North Sea habitat-building seamlessly met the joyful, sensory experiences of our local community.

Now, as we prepare to slip her moorings one final time, we look back not with mixed feelings, but with profound pride. She has been the steadfast flagship for our company—her impact on our crew, our community, and our united effort to foster a vibrant Blue Economy is immeasurable. Her departure marks a triumphant milestone, making way as we update our fleet and vigorously propel our mission forward to cultivate thriving marine biodiversity.

Farewell, Southern Star. Thank you for being our laboratory, our sanctuary on the water, and for welcoming so many into the SeaGrown story.
