SEA Index Tools

Our tools

SEA Index offers a suite of tools to help inform and empower yacht owners, shipbuilders, captains and the wider yachting industry. We offer trusted, unbiased methods of assessing the energy intensity of superyachts (motor and sail), which are grounded in globally recognised methodologies and verified by a reputable third party.  

Through increased transparency, we aim to empower yacht owners with proactive measures to make informed decisions when buying, selling or chartering a vessel.

SEA Index
quick tool

Our online tool to quickly provide an initial indication of the energy intensity of yachts over 24m, based on entered data.

SEA Index certification

The flagship SEA Index CO2 certification calculates the carbon emissions of yachts over 24m. The energy intensity of your yacht is then compared to industry benchmarks to determine its relative environmental performance, and a rating of one to five stars is given.

RINA lifecycle
emissions performance

Developed in collaboration with RINA, an operational efficiency assessment method to evaluate the lifecycle emissions of yachts over 25m and 400 Gross Tons, based on the choice of fuel.
