Balancing the strictly enforced emissions regulations while meeting client demands to construct luxury sailing vessels poses an engineering challenge for even the most exacting superyacht builders. The International Maritime Organization (IMO) has placed strict limits on Nitrous Oxide Emissions (NOx), and laws have been in effect since 2016 to enforce restrictions on vessels that operate within Nitrous Emissions Control Areas (NECAs). Many superyacht builders within the industry have struggled to come up with an elegant solution to the IMO Tier III’s emissions requirements and have been forced to rely on systems like SCR - Selective Catalytic Reduction.
