23、33 Bibliograph y 36 iv COPYRIGHT European Committee for StandardizationLicensed by Information Handling ServicesEN IS0 11812:2001 Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing Intern
24、ational Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with
25、 ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISOAEC Directives, Part 3 Draft International Standard
26、s adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be
27、 the subject of patent rights. IS0 shall not be held responsible for identifying any or all such patent rights. International Standard IS0 11812 was prepared by Technical Committee ISO/TC 188, Small craft. Annexes B, C, D and E form a normative part of this International Standard. Annex A is for inf

V COPYRIGHT European Committee for StandardizationLicensed by Information Handling ServicesEN IS0 11812:2001 I nt rod uction The compliance to this International Standard may not be required to show that a boat fulfils the essential safety requirements of the Directive 94/25/EC, but i
29、t may be required by IS0 12217. vi COPYRIGHT European Committee for StandardizationLicensed by Information Handling ServicesEN IS0 11812:2001 Small craft - Watertight cockpits and quick-draining cockpits 1 Scope This International Standard specifies requirements for cockpits and recesses to be desig
30、nated either as “watertight” or as “quick-draining” on small craft of hull length up to 24 m. It does not set requirements for the size and shape of a cockpit or recess, nor when or where it shall be used. It only considers draining by gravity, and not by pumping or other methods. NOTE 1 The term “q
31、uick-draining cockpit” has been chosen to differentiate from the common understanding of “self-draining cockpit” where water may be drained overboard in certain conditions, but without specified draining speed, height of bottom or sill. etc. NOTE 2 Examples of single-plane cockpit bottoms are given

38、ollowing design categories apply: A: Ocean: Designed for extended voyages where conditions may exceed wind force 8 (Beaufort scale) and significant wave heights of 4 m and above, and vessels largely self-sufficient; but excluding abnormal conditions such as hurricanes. B: Offshore: Designed for offs
39、hore voyages where conditions up to and including wind force 8 and significant wave heights up to and including 4 m may be experienced; 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 h
40、eights up to and including 2 m may be experienced; D: Sheltered waters: Designed for voyages in close coastal waters, small bays, lakes, rivers and canals where conditions up to and including wind force 4 and maximum wave heights up to and including 0,3 m may be experienced. 3.2 length of hull lengt
