SEA Index®

The benchmark for measuring a yacht’s environmental impact

The SEA Index® tool measures a yacht’s environmental impact, enabling clear and meaningful comparisons across different vessels acquiring insights on how to improve.

The Superyacht Eco Association (SEA) Index, created by the Yacht Club de Monaco and Crédit Suisse (UBS Group), is the definitive tool for modern yachting, bridging the gap between maritime prestige and environmental responsibility.

Delivering long‑term performance, cost efficiency, and freedom at sea, the SEA Index stands as a true mark of excellence. It brings together yacht owners, ports, marinas, and key industry stakeholders around a shared commitment: building a sustainable, future‑focused vision for our oceans.

Let’s shape the future of responsible yachting together.
