The Yachts for Science program seeks to use existing assets to improve ocean access and advance global knowledge to improve the state of the ocean. Often one of the greatest challenges for marine scientists is access to the sea to undertake their research. Private yachts, above 24 metres, often have spare berths or downtime between private use or charter that could be deployed to support marine scientists. We match yachts with marine scientists to enable access to the ocean to carry out their critical research work and inform decision and policy makers to enable the protection and recovery of our oceans.
