Based on the rugged and beautiful north coast of Cornwall, we are pioneers in Regenerative Mariculture. We combine expertise and experience with cutting-edge processes to help create a sustainable future for Cornwall.

Sugar Kelp

Scientific name: Saccharina Latissima (Sugar Kelp, Sweet Kelp or Kombu Royale).

It is a native species that is found naturally in shallow, inshore waters at depths of up to 30m. Sugar Kelp grows particularly quickly in early spring and gets its name from the sweet white powder (mannitol) that comes to the surface as the seaweed dries. Growing kelp has enormous potential to benefit our local coastline and communities as well as the planet.




Fresh Water


Pesticides or Fertilisers


Why should we grow Seaweed?

  • Beneficial to regenerating ocean ecosystems
  • Removal of excess nutrients
  • Absorption of pollutants like heavy metals and phenolic compounds
  • Carbon sequestration
  • Restore water pH
  • Reduce local algal blooms and methane emissions
  • Positive bioenergy production
  • Highly nutritious

Where will the farm be?

We have carefully selected a low-traffic location for the farm three kilometres offshore in our home waters of Port Isaac:

  • Offshore
  • Minimal commercial and leisure traffic
  • Far enough offshore to ensure minimal visual impact
  • Far enough offshore to minimise potential impact on local surf conditions
  • Located in 25-30m of water over a historic trawling ground

What is seaweed used for?

Seaweed already has a range of uses, and there is likely more to come as our knowledge and technology matures. Current uses include:

  • Energy
  • Fertilisers
  • Biostimulants
  • Food and animal feed
  • Cosmetics, nutraceuticals, pharmaceuticals and chemicals (bioplastics)

How will local communities benefit?

It's not just the environment that will benefit from our farm:

  • Clean and renewable energy
  • Carbon sequestration
  • Whole life carbon and circular economy
  • Climate resilience and adaptation
  • Natural capital and regenerating ecosystems
  • Biodiversity and environmental net gain
  • Habitat creation and restoration
  • High-quality jobs, training, and apprenticeships

Blue Solutions

Seaweed is a remarkable environmental asset, acting as a natural carbon sink. There is a growing body of research suggesting seaweed absorbs and sequesters carbon dioxide, a crucial factor in mitigating climate change as well as regulating the local nitrogen levels.

Our Team



North Cornwall-based, Ross grew up fishing, surfing and sailing the North Cornish coast with his father and grandfather and was an RNLI lifeboat crewman. He trained in business and maritime law at Plymouth University.



After a decorated military career, Harry co-founded a successful maritime risk company. He has strong family ties to North Cornwall and his love of the sea is put to further service as an Ambassador for the Sailors' Society.

Local Social responsibility

We strongly believe in the importance of giving back to our community, as part of that, we pledge to:


Support the organisations closest to our hearts: The RNLI, Fishermen's Mission, the Sailors' Society and the Marine Society.


Develop an mariculture outreach and education programme to engage with local school children including farm visits and seaweed workshops. Collaborate with universities to enrich studies and share data.


As the business develops we will offer work experience and a limited number of apprenticeship places for eligible local school-leavers.


How will the seaweed farm impact local biodiversity?

Will the farm impact surf conditions at nearby beaches?

Who owns the site?

Can fish or marine mammals get tangled in the farm infrastructure?

Will the view of the sea from an AONB/CNL be affected?

Will equipment from the farm such as ropes and buoys wash up on the shore?

How did you select the site?

Have you taken into consideration local sea conditions?

Are you concerned about seawater quality in North Cornwall

Do you support the UN Sustainable Development Goals?

What do The experts say?

"World Wildlife Foundation is interested in seaweed farming and seeing it expand because of all the many benefits that it can provide both for our oceans as well as for coastal communities."

"Our extensive and under-utilised coastline makes the UK an ideal environment for seaweed production. There is potential to farm seaweed along extensive stretches of our coast. This would significantly increase production beyond our current levels."

"Seaweed provides an unlimited number of solutions to support food systems, to provide new medicines, to replaces plastics, restore biodiversity & clean the ocean and provide new source of revenues to communities where fishing is declining. Seaweed is also one of the most scalable nature-based solutions for both decarbonizing the economy and sequestering carbon from the surface of the ocean."
