The work of preparing International Standards is normally carried out through ISO technical committees. Each
26、 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 ISO, also take part in the work. ISO collaborates closely with the Internationa
27、l Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for
28、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 the subject of patent rights. ISO shall not be held responsible for identifyi
29、ng any or all such patent rights. International Standard ISO 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 information only. 5egaP ENISO11812:2001 ISO 11812:2001(E) vi Introduction The com
30、pliance 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 it may be required by ISO 12217. 6egaP ENISO11812:2001 INTENRATIONALS TANDA DR IS:21811 O1002(E)1Small craft Watertight cockpits and quick-draining
31、cockpits 1 Scope This International Standard specifies requirements for cockpits and recesses to be designated 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 shal
32、l be used. It only considers draining by gravity, and not by pumping or other methods. NOTE 1 The term “quick-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
33、draining speed, height of bottom or sill, etc. NOTE 2 Examples of single-plane cockpit bottoms are given in informative annex A. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. Fo
34、r dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. Fo
35、r undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

ENISO11812:20011ISO 11812:2001(E) 2 3 Terms and definitions For the purposes of this International Standard, the following terms and definitions apply. 3.1 design categories description of the sea and wind conditions for which a boat is assessed to be sui
39、table NOTE The following 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: D
40、esigned for offshore 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 si
41、gnificant wave heights 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 leng
42、th of hull L Hlength of the hull according to ISO 8666 NOTE Length of hull is expressed in metres. 3.3 maximum beam B max overall beam of monohull or multihull craft according to ISO 8666 NOTE Maximum beam is expressed in metres. 3.4 waterline WL waterline in the fully loaded ready-for-use condition
43、 3.5 freeboard amidships F M freeboard at mid-waterline in fully loaded ready-for-use condition according to ISO 8666 3.6 sailing boat boat designed to use sails as its primary means of propulsion, as defined in ISO 12217-2 3.7 non-sailing boat boat not designed to use sails as primary means of prop
44、ulsion, as defined in ISO 12217-1 3.8 cockpit and recess any area that may retain water, however briefly, due to rain, waves, boat heeling, etc. ENISO11812:20012ISO 11812:2001(E) 3NOTE Cockpits are normally designed for accommodation of people but, for the purpose of this International Standard, the
45、 term “cockpit” will be used either for a proper cockpit or for any recess. This means that bulwarks may create a large cockpit, open boats may effectively comprise a cockpit which includes nearly all the boat, cockpit(s) may be situated anywhere in the boat, and a cockpit may open aft to the sea. 3
46、.9 watertight cockpit or recess cockpit or recess which satisfies the requirements of this International Standard for watertightness and sill heights, but not those for drainage 3.10 quick-draining cockpit or recess cockpit with characteristics and draining capacity which fulfil all the requirements
47、 of this International Standard for one or several design categories NOTE According to its characteristics, a cockpit may be considered quick-draining for one design category, but maybe not for a higher category. 3.11 cockpit sole essentially horizontal surface(s) of the cockpit on which people norm
48、ally stand 3.12 cockpit bottom lowest surface of the cockpit sole where water collects before being drained NOTE 1 Devices raising the standing level(s) from the rigid part of the cockpit sole, e.g. grating, stands, bridge decks, are not considered as part of the cockpit bottom. NOTE 2 The cockpit bottom is considered to comprise only one plane. A cockpit bottom with several levels is considered according
