Recreational craft and personal watercraft

Emissions regulations also exist for ‘recreational and personal watercraft’ – in other words boats and equipment such as jet-skis. The requirements cover boats for leisure use or sports (but not racing boats) with a hull length from 2.5m to 24m and personal watercraft up to 4m in length. Inboard, outboard and stern-drive engines and equipment using water jet pumps for propulsion are all covered. The first stage of European regulations was introduced in 2005 and a Stage II was introduced in January 2017. They do not generally require exhaust emissions aftertreatment, but this is the case in the USA for numerous applications.
