Earth 300 is an organization that aspires to both inspire and support oceanographic research and awareness of the climate crisis. It has released speculative designs for a scientific research vessel which, if built, would be the largest ever superyacht, 300 m (980 ft) long. It intends to host experts in diverse fields, enabling interdisciplinary research into climate change, oceanography, and sustainability issues. The vessel's distinctive appearance also aims to draw attention to the health of the climate and oceans. Earth 300 has assembled individuals from a variety of backgrounds and formed partnerships with companies to provide different aspects of the vessel's technology. The organization aims to launch the vessel in 2025.
