Note 1 to entry: The definitions of these design categories align with those used in the Recreational Craft Directive of the European Union, EU Directive 94/25/EC as amended.


3.12.1 design category B “offshore”


designed for offshore voyages where conditions up to and including wind force 8 and significant wave heights up to and including 4m can be experienced


3.12.2 design category C “inshore”


designed for voyages in coastal waters, large bays, estuaries, lakes and rivers where conditions up to and including wind force 6 and significant wave heights up to and including 2m can be experienced


3.12.3 design category D “sheltered waters”


designed for voyages in sheltered coastal waters, small bays, small lakes, rivers, and canals when conditions up to and including wind force 4 and significant wave heights up to and including 0,3m can be experienced, with occasional waves of 0,5m maximum height, for example from passing vessels
