The Sea Index has expanded its certification and developed new reference models for a broad range of pleasure boats.
The certification was originally developed for yachts above 24 metres, with 120 vessels certified for their CO2 emissions so far.
The expansion encompasses both monohulls and catamarans, with Sea Index working in collaboration with Lloyd’s Register to develop new reference models.
The certification will now cover displacement, semi-displacement, and planing monohull boats and production catamarans up to 35 metres, which Sea Index says will enable shipyards and manufacturers to integrate environmental performance from early design stages across larger production volumes.
Hydrodynamic performance
The expanded methodology will take into account differences in hydrodynamic performance associated with varying hull forms and speed regimes to evaluate a vessel’s environmental performance.
In addition, owners and buyers will be able to access comparable information, irrespective of vessel size, with the environmental assessment not limited to a small segment of the fleet, but progressively available across the full spectrum of boating.
“This expansion marks an important evolution for the SEA Index and for the boating industry at large,” said Bernard d’Alessandri, president of SEA Index and secretary general of the Yacht Club de Monaco.
“By extending the methodology to pleasure boats from 10 metres, including production vessels and catamarans, we are moving towards a more inclusive and accessible framework for environmental transparency.”
The SEA Index was developed by the Yacht Club de Monaco and is an environmental performance assessment tool for boats, designed to measure and compare their impact using objective, transparent, and independently verified criteria.
