Our Vision

This initiative is a response to the growing strong demand from yacht owners wishing to be able to calculate their environmental impact and support this industry in its transformation for a more eco-responsible future, as more and more yacht owners are adopting an approach of sustainability and environmental excellence. They are the ones who give the impetus, call on the shipyards and finance the research and development associated with their project.

Our Tool

The SEA index is a tailor-made tool for assessing and improving the environmental performance of yachts. It can be accessed online so that shipowners, captains or other Yachting professionals can carry out a « non-binding » self-assessment.
